Measles cases are increasing globally, including in the United States. The majority of measles cases imported into the United States occur in unvaccinated U.S. residents who become infected during international travel. A list of countries with confirmed measles outbreaks can be found on the Global Measles Travel Health Notice (THN) . Measles spreads rapidly in communities that are not fully vaccinated and may pose a risk to international travelers in places not included in the THN. CDC recommends all travelers get fully vaccinated against measles before traveling to any international destination.

What Vaccinations Are Recommended for Mexico?

T he most popular international destination for American travelers, Mexico is known for its white-sand beaches, awe-inspiring Mayan and Aztec ruins, culinary delights, colonial towns, and diverse landscapes. 

If you’re planning a trip south of the border, it’s important to know what vaccinations are recommended by the U.S. Centers for Disease Control and Prevention (CDC) for travel to this destination. (Be sure to visit your doctor at least a month prior to your trip to get any vaccines or medicines you may need.)

Recommended vaccines for travel to Mexico

As of October 2023, here are the current CDC guidelines:

Routine vaccinations

Vaccines the CDC recommends prior to every trip include those for chickenpox (varicella), diphtheria-tetanus-pertussis (DTaP), flu (influenza), measles-mumps-rubella (MMR), polio, and shingles.

COVID-19 is a highly contagious viral respiratory infection. It spreads when an infected person breathes out droplets or small particles containing the virus, which can then enter through the eyes, nose, or mouth of an uninfected person (or contaminate surfaces, in some cases). 

For everyone who is eligible, the CDC recommends being up to date on COVID-19 vaccinations.

Hepatitis A

Hepatitis A is a highly contagious liver infection that is caused by the hepatitis A virus. It is primarily spread when an uninfected person consumes food or water that has been contaminated by the feces of an infected person, or when an infected person uses dirty hands to prepare food.

This vaccine is recommended for unvaccinated travelers 1 year old or older who will be going to Mexico. Infants who are 6 months to 11 months old should also be vaccinated for hepatitis A. (According to the CDC, “the dose does not count toward the routine 2-dose series.”)

Those who are allergic to a component of the vaccine or who are under 6 months old should receive a single dose of immune globulin, which can provide protection for up to 2 months (depending on the dosage given).

Unvaccinated travelers who are over 40 years old, immunocompromised, or who have chronic health conditions who are departing to a “risk area” in less than 2 weeks are advised to get the initial dose of vaccine and at the same appointment receive immune globulin.

Hepatitis B

Hepatitis B is a serious liver infection caused by the hepatitis B virus. It is spread when blood, semen, or another bodily fluid from someone who is infected enters the body of someone who is not infected, as can happen during sexual contact, sharing drug-injection equipment, or during birth from mother to baby. 

The CDC recommends this vaccine for unvaccinated travelers younger than 60 going to Mexico, and notes that those 60 years old and up may get vaccinated prior to traveling to Mexico.

Malaria is a serious, sometimes fatal condition that is spread by a certain type of mosquito that feeds on humans.

For travelers going to certain parts of Mexico, the CDC recommends taking prescription medicine to prevent malaria. Depending on the medicine used, it will need to be taken multiple days prior to the trip, as well as during and after the travels. The CDC advises speaking with your doctor to determine which malaria medicine you should take.

Measles is a serious, highly contagious airborne disease that can lead to a variety of complications, including death. It is spread when an uninfected person comes into contact with infected nasal or throat secretions (for example, from coughing or sneezing) or breathes the air that was breathed by someone with the condition. 

The CDC recommends that infants 6 to 11 months old who are traveling internationally get one dose of the measles-mumps-rubella (MMR) vaccine before their trip. (The dose does not count as part of the routine childhood vaccination series.)

(Note that measles is also listed among the CDC’s “routine vaccinations” above.)

Rabies is a viral disease most often spread through the bite of an infected, or “rabid,” animal. It infects the central nervous system in mammals, causing disease in the brain and, ultimately, death.

The CDC notes that rabid dogs are commonly found in Mexico and adds that rabies treatment is often available locally if you are bitten or scratched by a dog or other mammal in Mexico. The organization suggests that those who will be around dogs or wildlife on their travels, such as campers, cave explorers, veterinarians and other animal handlers, and visitors to rural areas should consider rabies vaccination prior to their trip. (A more complete list of those who should consider rabies vaccine is available on the CDC’s website .) Because children are more likely to be bitten or scratched by a dog or other animal, rabies vaccine should also be considered for this group prior to travel to Mexico.

Typhoid is a bacterial condition caused by salmonella bacteria. It is spread when an uninfected person consumes food or beverages that have been prepared by a person shedding the bacteria or when sewage contaminated with the bacteria gets into the water a person uses for drinking or washing food.

The CDC recommends the typhoid vaccine for most travelers, and particularly for those who will be staying with friends or relatives or visiting smaller cities or rural areas.

Last-minute reminders

Prior to any travel to Mexico, be sure to check the official CDC Traveler’s Health page , as vaccination recommendations may have been updated since the publication of this article.

Organized crime activity – including gun battles, murder, armed robbery, carjacking, kidnapping, forced disappearances, extortion, and sexual assault – is common along the northern border and in Ciudad Victoria. Criminal groups target public and private passenger buses, as well as private automobiles traveling through Tamaulipas, often taking passengers and demanding ransom payments.

Heavily armed members of criminal groups often patrol areas of the state and operate with impunity particularly along the border region from Reynosa to Nuevo Laredo.  In these areas, local law enforcement has limited capacity to respond to incidents of crime. Law enforcement capacity is greater in the tri-city area of Tampico, Ciudad Madero, and Altamira, which has a lower rate of violent criminal activity compared to the rest of the state.

U.S. citizens and LPRs have been victims of kidnapping.

Destination Description

See the  State Department’s Fact Sheet on Mexico  for more information on U.S.-Mexico relations.

Entry, Exit and Visa Requirements

A valid passport book is required to enter Mexico by air, and those attempting to enter at an airport with a U.S. passport card only may be denied admission.

Review the Mexican government’s most current  entry, exit, and visa requirements  ( Spanish only ) or visit the  Embassy of Mexico  in Washington, D.C., for more information.

For travelers entering Mexico by air only, Mexican immigration authorities implemented a process to replace the previous paper Forma Migratoria Multiple or FMM with a Forma Migratoria Multiple Digital or FMMD.  The FMMD process is in place at all 66 international airports in Mexico.  Upon arrival at an airport, Mexican immigration authorities will determine a traveler’s authorized length of stay and either place a date stamp in the traveler’s passport or direct the traveler through a self-service electronic gate (E-Gate) that will generate a printed receipt with QR code. Air travelers who wish to download a record of their FMMD or find more information on the FMMD process may visit the National Migration Institute’s (INM) website .

Travelers entering Mexico by land should have a valid passport book or card.  If you enter Mexico by land and plan to travel beyond the immediate border area (approximately 12 miles or 20 kilometers into Mexico), you must stop at an INM office to obtain an entry permit (Forma Migratoria Multiple or FMM), even if not explicitly directed to do so by Mexican officials.  INM may opt to allow tourists entry of up to 180 days without a visa or may limit authorized stays to shorter periods at their discretion; visitors should confirm the specific length of authorized stay written on the entry permit (FMM) or by the stamp in their passport. Mexican immigration authorities could ask you to present both your passport and entry permit if applicable at any point and may detain you while they review your immigration status if you are not carrying your passport and proof of legal status in Mexico, or if you have overstayed your authorized stay. Immigration check points are common in the interior of Mexico, including in popular tourist areas far from the border.  

You will also need a temporary vehicle import permit to bring a U.S.-registered vehicle beyond the border zone. These permits are processed through Banjercito and require a deposit that will be refunded once the vehicle leaves Mexico.  For more information, visit the  Banjercito  website ( Spanish only ).

Baja California, Baja California Sur, and Sonora have a “hassle-free” zone that allows cars traveling without an entry permit or car registration within the zone. 

Mexican authorities can impound a vehicle that enters the country without a valid U.S. registration, a vehicle driven by a Mexican national who is not resident in the United States, or a vehicle found beyond the border zone without the temporary import permit.

Mexican law permits Mexican immigration authorities to deny foreigners entry into Mexico if they have been charged with or convicted of a serious crime in Mexico or elsewhere.

Travelers bringing in goods beyond their personal effects worth $300.00 or more must declare those goods with Mexican customs (SAT) Mexican customs  ( Spanish only ) or risk having them confiscated. This also applies to used goods or clothing, including items for donation. U.S. citizens driving such items into Mexico without declaring them or without sufficient funds to pay duty fees are subject to having their vehicle seized by Mexican customs authorities. For further information about customs regulations, please read our  customs information page .

The U.S. Department of State is unaware of any HIV/AIDS entry restrictions for visitors to or foreign residents in Mexico.

A parent or legal guardian departing Mexico with minor children should carry a notarized consent letter from the other parent if traveling separately. INM requires at least one parent to complete a  SAM  ( Formato de Salida de Menores, Spanish only ) for all Mexican or foreign minors with Temporary Resident, Temporary Student Resident, or Permanent Resident status departing Mexico alone or with a third party.  Further information about the  prevention of international parental child abduction  is available on our website.

Find information on dual nationality , and customs regulations on our websites. Both Mexico and the United States allow dual nationality.

Safety and Security

Travelers are urged to review the  Mexico Travel Advisory  for information about safety and security concerns affecting the country on a state-by-state basis.

U.S. citizens traveling to and residing in Mexico should not expect public health and safety standards like those in the United States. Even where such standards exist, enforcement varies by location. Travelers should mitigate the risk of illness or injury by taking standard health and safety precautions.

The phone number to report emergencies in Mexico is “911.”  Although there may be English-speaking operators available, it is best to seek the assistance of a Spanish speaker to place the call.

Crime:  Crime in Mexico occurs at a high rate and can be violent, from random street crime to cartel-related attacks. Over the past year, Mission Mexico has assisted U.S. citizens who were victims of armed robbery, carjacking, extortion, homicide, kidnapping, pick-pocketing, and sexual assault. Increased levels of cartel-related violence have resulted in territorial disputes and targeted killings, injuring or killing innocent bystanders. Travelers who find themselves in an active shooter scenario should flee in the opposite direction, if possible, or drop to the ground, preferably behind a hard barrier.

Drivers on roads and highways may encounter government checkpoints, which often include National Guard or military personnel. State and local police also set up checkpoints in and around cities and along the highways to deter criminal activity and enforce traffic laws. In some parts of Mexico, criminal organizations and other non-governmental actors have been known to erect unauthorized checkpoints and have abducted or threatened violence against those who fail to stop and/or pay a “toll.” When approaching a checkpoint, regardless of whether it is official, cooperate and avoid any actions that may appear suspicious or aggressive.

While Mexican authorities endeavor to safeguard the country’s major resort areas and tourist destinations, those areas have not been immune to the types of violence and crime experienced elsewhere in Mexico. In some areas of Mexico, response time of local police is often slow. In addition, filing police reports can be time consuming. See our  Mexico Travel Advisory  for more information.

Demonstrations  occur frequently.  They may take place in response to political or economic issues, on politically significant holidays, and during international events.  Protesters in Mexico may block traffic on roads, including major thoroughfares, or take control of toll booths on highways.  Travelers who encounter protesters who demand unofficial tolls are generally allowed to pass upon payment.  U.S. citizens should avoid participating in demonstrations or other activities that might be deemed political by authorities, as Mexican law prohibits political activities by foreign citizens and such actions may result in detention or deportation.

• Demonstrations can be unpredictable, avoid areas around protests and demonstrations.  
• Past demonstrations have turned violent.
• Check local media for updates and traffic advisories.  

International Financial Scams:  See the  Department of State  and the  FBI  pages for information.  

Internet romance and financial scams are prevalent in Mexico. Scams are often initiated through Internet postings/profiles or by unsolicited emails and letters. Scammers almost always pose as U.S. citizens who have no one else to turn to for help. Common scams include:   

• Romance/Online dating 
• Money transfers 
• Lucrative sales 
• Grandparent/Relative targeting 
• Free Trip/Luggage 
• Inheritance notices 
• Bank overpayments 

Mexico’s consumer protection agency,  PROFECO  (Procuraduría Federal del Consumidor, Spanish only), can sometimes  provide assistance  (Spanish only) to victims of such scams. In addition, there have been allegations of banking fraud perpetrated by private bankers against U.S. citizens. U.S. citizens who believe they have been victims of fraud can file a police report  file a complaint  (Spanish only) with the Mexican banking regulatory agency, CONDUSEF  (Comision Nacional para la Proteccion y Defensa de los Usuarios de Servicios Financieros, Spanish only), or consult with an attorney.

Victims of Crime:  U.S. victims of sexual assault are encouraged to contact the U.S. Embassy or nearest Consulate for assistance.  Report emergencies to the local police at 911, report crimes already committed to the Ministerio Publico, and contact the Embassy or Consulate at +52-55-85262561.  Remember that local authorities are responsible for investigating and prosecuting crimes.

U.S. citizen victims of crime should contact the local authorities to file a Mexican police report before departing Mexico. In most instances, victims of crime will file reports with the Ministerio Publico (equivalent to the office of public prosecutor or district attorney in the United States) and not with police first responders. U.S. citizens should also inform the  U.S. Embassy or nearest consulat e . 

See our webpage on  help for U.S. victims of crime overseas .    We can:

• help you find appropriate medical care,
• assist you in reporting a crime to the police,
• contact relatives or friends with your written consent,
• provide general information regarding the victim’s role during the local investigation and following its conclusion, 
• provide a list of local attorneys,
• provide information on  victim’s compensation programs in the United States ,
• provide an emergency loan for repatriation to the United States and/or limited medical support in cases of destitution,
• help you find accommodation and arrange flights home,
• replace a stolen or lost passport.

Domestic Violence:  U.S. citizen victims of domestic violence are encouraged to contact the  U.S. Embassy or nearest consulate  for assistance.

Kidnapping:  Mexico experiences very high rates of kidnapping.  If you believe you or your U.S. citizen or Lawful Permanent Resident (LPR) relative has been kidnapped, please contact the U.S. Embassy or nearest consulate immediately.

Robbery:  Mexico experiences robberies, typically in cities, in which abductors force victims to use their debit or credit card to withdraw money from ATMs in exchange for their release. Perpetrators commonly work in cooperation with, or pose as, taxi drivers. To minimize the risk of such robberies:

• Only use a reputable taxi company or a trusted ride-sharing app.
• Book taxis through your hotel or an authorized taxi stand.

Extortion:  Extortion schemes are common in Mexico.  In a typical scheme known as a virtual kidnapping, criminals convince family members that a relative has been abducted, when, in fact, the person is safe but unreachable.  The purported abductors will often use threats to persuade victims to isolate themselves, making communication with family members less likely.  Unable to reach their loved ones, family members often consent to paying the “ransom” demand.  Criminals use various means to gather information about potential victims, including monitoring social media sites, eavesdropping on conversations, or using information taken from a stolen cell phone.  Some of these extortions have been conducted from Mexican prisons.  You can reduce the risk of falling victim to this type of extortion through the following:

• Do not discuss travel plans, your room number, or any other personal information within earshot of strangers.
• Do not divulge personal business details to strangers in person or over the phone, especially when using hotel phones.
• If you are threatened on the phone, hang up immediately.

Sexual Assault:  Rape and sexual assault are serious problems in some resort areas. Many of these incidents occur at night or during the early morning hours, in hotel rooms, on hotel grounds, or on deserted beaches. In some cases, assailants drug the drinks of victims before assaulting them. Pay attention to your surroundings and to who might have handled your drink.

Credit/Debit Card “Skimming:”  There have been instances of fraudulent charges or withdrawals from accounts due to “skimmed” cards. If you choose to use credit or debit cards, you should regularly check your account to ensure there are no unauthorized transactions. Travelers should limit the amount of cash they carry in public, exercise caution when withdrawing cash from ATMs, and avoid ATMs located in isolated or unlit areas.

Alcohol:  If you choose to drink alcohol, it is important to do so in moderation and to stop and seek medical attention if you begin to feel ill. There have been reports of individuals falling ill or blacking out after consuming unregulated alcohol. The Mexican Federal Commission for the Protection against Sanitary Risk,  COFEPRIS  ( Comision Federal para la Proteccion contra Riesgos Sanitarios, Spanish only ), is responsible for inspecting hotels, restaurants, and other establishments for health violations, including reports of unregulated alcohol. Please email COFEPRIS at  [email protected]  for more information or if you wish to file a report. You can file a report online (Spanish only) via the COFEPRIS website, by calling the COFEPRIS call center at 800 033 50 50 (from Mexico) or +52 (55) 5080-5425 (from the United States), or by scheduling an appointment  (Spanish only)  to visit a COFEPRIS office.

There have also been instances of criminals drugging drinks to rob or sexually assault victims. Additionally, if you feel you have been the victim of unregulated alcohol or another serious health violation, you should notify the U.S. Embassy or nearest consulate . You may also contact the U.S. Department of State – Bureau of Consular Affairs in Washington, D.C. at 1-888-407-4747 (toll-free in the United States and Canada) or 1-202-501-4444 (from all other countries).

Drug Smuggling:  Mexican criminal organizations are engaged in a violent struggle to control trafficking routes. Criminal organizations smuggling drugs into the United States have targeted unsuspecting individuals who regularly cross the border. Frequent border crossers are advised to vary their routes and travel times and to closely monitor their vehicles to avoid being targeted.

Tourism:  In major cities and resort areas, the tourism industry is generally well-regulated.  Best practices and safety inspections are regularly enforced.  Hazardous areas and activities are identified with appropriate signage, and professional staff is typically on hand in support of organized activities.  In the event of an injury, appropriate medical treatment is widely available throughout the country.  Outside of a major metropolitan center, it may take more time for first responders and medical professionals to stabilize a patient and/or provide life-saving assistance.  In smaller towns and areas less commonly frequented by foreign tourists, the tourism industry is unevenly regulated, and safety inspections for equipment and facilities do not commonly occur.  Hazardous areas/activities are not always identified with appropriate signage, and staff may not be trained or certified either by the host government or by recognized authorities in the field.  In the event of an injury, appropriate medical treatment is typically available only in or near major cities.  First responders are generally unable to access areas outside of major cities to provide urgent medical treatment.  U.S. citizens are encouraged to purchase medical evacuation insurance . 

Since 2016, Mexico has opened seven multilingual Centers for the Care and Protection of Tourists (CAPTA) and Tourist Assistance Centers (CATTAC) in Los Cabos, La Paz, Acapulco, Playa del Carmen, Mazatlan, Ciudad Madero, and Queretaro. These offices have proven helpful assisting U.S. citizen visitors in resolving disputes with merchants and government entities, filing criminal reports, securing needed services, and locating special needs accommodations. 

Local Laws & Special Circumstances

Criminal Penalties:  You are subject to local laws. If you violate local laws, even unknowingly, you may be expelled, arrested, or imprisoned. Individuals establishing a business or practicing a profession that requires additional permits or licensing should seek information from the competent local authorities prior to practicing or operating a business.

Furthermore, some laws are also prosecutable in the United States, regardless of local law. For examples, see our website on  crimes against minors abroad  and the  Department of Justice  website.

Arrest Notification:  If you are arrested or detained, ask police or prison officials to notify the U.S. Embassy or nearest consulate immediately. See our  webpage  for further information.

The Mexican government is required by international law to contact the U.S. Embassy or consulate promptly when a U.S. citizen is arrested if the arrestee so requests.  This requirement does not apply to dual nationals.  

Firearms and Other Weapons:  Weapons laws in Mexico vary by state, but it is generally illegal for travelers to carry weapons of any kind including firearms, knives, daggers, brass knuckles, as well as ammunition (even used shells). Illegal firearms trafficking from the United States to Mexico is a major concern, and the Department of State warns all U.S. citizens against taking any firearm or ammunition into Mexico. If you are caught entering Mexico with any type of weapon, including firearms or ammunitions, you likely will face severe penalties, including prison time. U.S.-issued permits allowing an individual to carry weapons are not valid in Mexico.  Visit the Department’s  Traveling Abroad with Firearms webpage .

Vessels entering Mexican waters with firearms or ammunition on board must have a permit previously issued by a Mexican embassy or consulate.

Drugs:  Drug possession and use, including medical marijuana, is illegal in Mexico and may result in a lengthy jail sentence or fines.  

Electronic Cigarettes (Vaping Devices):  It is illegal for travelers to bring electronic cigarettes (vaping devices) and all vaping solutions to Mexico. Customs will confiscate vaping devices and solutions and travelers could be fined or arrested. Avoid delays and possible sanctions by not taking these items to Mexico. 

Real Estate and Time Shares:  U.S. citizens should exercise caution when considering time-share investments or purchasing real estate and be aware of the aggressive tactics used by some sales representatives. Before initiating a real estate purchase or time-share investment, U.S. citizens should consult with a Mexican attorney to learn about important regulations and laws that govern real estate property.

Mountain Climbing and Hiking:  The Mexican government has declared the area around the Popocatepetl and the Colima volcanoes off limits. In remote rural areas, there can be limited cell phone coverage and internet connectivity, and it may be difficult for rescue teams and local authorities to reach climbers and hikers in distress.

Potential for Natural Disasters:  Mexico is in an active earthquake zone. Tsunamis may occur following significant earthquakes. Please visit our  disaster and crisis preparedness  webpage for more information. For additional information concerning disasters, see:

• U.S. Embassy Mexico City website
• Civil Protection  ( Proteccion Civil, Spanish only ) provides information from the Mexican Government about natural disaster preparedness
• U.S. Federal Emergency Management Agency (FEMA)  provides general information about natural disaster preparedness
• U.S. Geological Survey  provides updates on recent seismic and volcanic activity

Storm Season:  Tropical storms in the Gulf of Mexico or along the Caribbean and Pacific Coast between May and November can produce heavy winds and rain. Please visit our disaster and crisis preparedness  webpage for more information.

Spring Break:  Millions of U.S. citizens visit Mexican beach resorts each year, especially during “ spring break ” season. The legal drinking age in Mexico is 18. See the “Alcohol” section above to learn more about the risks associated with drinking, as well as reports of illnesses associated with the possible consumption of unregulated alcohol.

Resort Areas and Water Activities:  Beaches in Mexico may be dangerous due to strong currents, rip tides, and rogue waves. Warning notices and flags on beaches should be taken seriously. Not all hazardous beaches are clearly marked. If black or red warning flags are up, do not enter the water. Strong currents can lead to dangerous conditions for even the most experienced swimmers. U.S. citizens simply walking along the shore or wading have been swept out to sea by rogue waves, and some citizens have drowned or disappeared at Mexican beaches. Avoid the consumption of alcohol while engaging in water activities and do not swim alone. 

Boats used for excursions may not be covered by accident insurance and sometimes lack adequate life jackets, radios, and tools to make repairs.  Participation in adventure sports may not be covered by accident insurance and safety protections and regulations for these activities may differ from U.S. standards.  Visit  our website  and the U.S. Centers for Disease Control and Prevention website for more information about adventure travel.

Counterfeit and Pirated Goods:  Although counterfeit and pirated goods are prevalent in many countries, they may still be illegal according to local laws. You may also be subject to fines or forced to relinquish the goods if you bring them back to the United States. See the  U.S. Department of Justice website  for more information.

Faith-Based Travelers:  See the following webpages for details:

• Faith-Based Travel Information
• International Religious Freedom Report  – see country reports
• Human Rights Report  – see country reports
• Hajj Fact Sheet for Travelers
• Best Practices for Volunteering Abroad

LGBTQI+ Travelers:  There are no legal restrictions on same-sex sexual relations or on the organization of Lesbian, Gay, Bisexual, Transgender, or Intersex (LGBTQI+) events in Mexico. However, due to sporadic reports of violence targeting LGBTQI+ individuals, U.S. citizens should exercise discretion in identifying themselves publicly as LGBTQI+. See our LGBTQI+ Travel Information page and Section 6 of the  Department of State’s Human Rights Report for Mexico  for further details.

Travelers with Disabilities:   Mexican law prohibits discrimination against persons with physical, sensory, intellectual, or mental disabilities.  Social acceptance of persons with disabilities in public is not as prevalent as in the United States.  The most common types of accessibility may include accessible facilities, information, and communication/access to services/ease of movement or access.  Expect accessibility to be limited in public transportation, lodging, communication/information, and general infrastructure in more rural and remote parts of the country, and more common in public transportation, lodging, communication/information, and general infrastructure in major cities.  U.S. citizens with disabilities should consult individual hotels and service providers in advance of travel to ensure they are accessible.

Students:  See our  Students Abroad  page and  FBI travel tips .

Women Travelers:  There were several reports of sexual assault or domestic violence involving U.S. citizen women over the past year. See our travel tips for  Women Travelers .

Excellent health facilities are available in Mexico City and other major cities. Ambulance services are widely available, but training and availability of emergency responders may be below U.S. standards. Injured or seriously ill travelers may prefer to take a taxi to a health provider. Mexican facilities often require payment “up front” before providing medical care, and most hospitals in Mexico do not accept U.S. health insurance. A list of doctors and hospitals is available on the U.S. Embassy or consulate website.

U.S. citizens have lodged complaints against some private hospitals in Cancun, the Riviera Maya, and Los Cabos to include exorbitant prices and inflexible collection measures.  Travelers should obtain complete information on billing, pricing, and proposed medical procedures before agreeing to any medical care in these locations.  Be aware that some resorts have exclusive agreements with medical providers and ambulance services, which may limit your choices in seeking emergency medical attention.  Some hospitals in tourist centers utilize sliding scales, deciding on rates for services based on negotiation and on the patient’s perceived ability to pay.  In some instances, providers have been known to determine the limits of a patient’s credit card or insurance, quickly reach that amount in services rendered, and subsequently discharge the patient or transfer them to a public hospital.

Visit the  U.S. Centers for Disease Control and Prevention  website for information on Medical Tourism.

For emergency services in Mexico, dial  911 .  Although there may be English-speaking operators available, it is best to seek the assistance of a Spanish speaker to place the call.

Ambulance services are: 

• widely available in major cities but training and availability of emergency responders may be below U.S. standards,
• not present in many remote and rural areas of the country,   
• not equipped with state-of-the-art medical equipment.  
• Injured or seriously ill travelers may prefer to take a taxi or private vehicle to the nearest major hospital rather than wait for an ambulance.  

We do not pay medical bills:  Be aware that U.S. Medicare/Medicaid does not apply overseas.  Most hospitals and doctors overseas do not accept U.S. health insurance.  

Medical Insurance:  Make sure your health insurance plan provides coverage overseas.  Most care providers overseas only accept cash payments. See  our webpage  for more information on insurance coverage overseas. Visit the U.S. Centers for Disease Control and Prevention for more information on type of insurance you should consider before you travel overseas. 

We strongly recommend  supplemental insurance  to cover medical evacuation as well.

Always carry your prescription medication in original packaging, along with your doctor’s prescription.  Check the Mexican government’s Drug Schedule to ensure the medication is legal in Mexico. 

Vaccinations:  Be up-to-date on all  vaccinations  recommended by the U.S. Centers for Disease Control and Prevention.

Further health information :

• World Health Organization
• U.S. Centers for Disease Control and Prevention ( CDC)

Air Quality: Visit AirNow Department of State for information on air quality at U.S. Embassies and Consulates.

The U.S. Embassy maintains a list of doctors and hospitals .  We do not endorse or recommend any specific medical provider or clinic. 

Medical Tourism and Elective Surgery: 

• U.S. citizens have suffered serious complications or died during or after having cosmetic or other elective surgery.   
• Medical tourism is a rapidly growing industry. People seeking health care overseas should understand that medical systems operate differently from those in the United States and are not subject to the same rules and regulations.  Anyone interested in traveling for medical purposes should consult with their local physician before traveling and visit the U.S. Centers for Disease Control and Prevention website for more information on Medical Tourism.  
• We strongly recommend supplemental insurance  to cover medical evacuation in the event of unforeseen medical complications.  
• Your legal options in case of malpractice are very limited in Mexico.  Several foreigners have successfully enlisted the support of  PROFECO  (Spanish only) in order to resolve disputes over medical services.
• Although Mexico has many elective/cosmetic surgery facilities that are on par with those found in the United States, the quality of care varies widely.  If you plan to undergo surgery in Mexico, make sure that emergency medical facilities are available and professionals are accredited and qualified.  

Pharmaceuticals

• Exercise caution when purchasing medication overseas.  Pharmaceuticals, both over the counter and requiring prescription in the United States, are often readily available for purchase with little controls.  Counterfeit medication is common and may prove to be ineffective, the wrong strength, or contain dangerous ingredients.  Medication should be purchased in consultation with a medical professional and from reputable establishments.  
• The Drug Enforcement Agency reports counterfeit prescription pills are sold by criminals on both sides of the border. These pills are sometimes represented as OxyContin, Percocet, Xanax, and others, and may contain deadly doses of fentanyl. Counterfeit pills are readily advertised on social media and can be purchased at small, non-chain pharmacies in Mexico along the border and in tourist areas.  U.S. citizens have become seriously ill or died in Mexico after using synthetic drugs or adulterated prescription pills.
• U.S. Customs and Border Protection and the Food and Drug Administration are responsible for rules governing the transport of medication back to the United States.  Medication purchased abroad must meet their requirements to be legally brought back into the United States.  Medication should be for personal use and must be approved for usage in the United States.  Please visit the U.S. Customs and Border Protection and the Food and Drug Administration websites for more information.   
• Visit the  Mexican Health Department  website (Spanish only) or contact the  Embassy of Mexico  in Washington, D.C., for more information about obtaining a permit to import medicine into Mexico.
• For a list of controlled substances in Mexico, visit the  COFEPRIS  website (Spanish only) and the  Mexican Drug Schedule  (Spanish only). U.S. citizens should carry a copy of their prescription or doctor’s letter, but it is still possible that they may be subject to arrest for arriving in Mexico with substances on these lists. Note that a medicine considered “over the counter” in some U.S. states may be a controlled substance in Mexico. For example, pseudoephedrine, the active ingredient in Sudafed, is considered a controlled substance in Mexico. For more information, contact the  Embassy of Mexico  in Washington, D.C.

Assisted Reproductive Technology and Surrogacy  

• If you are considering traveling to Mexico to have a child using assisted reproductive technology (ART) including surrogacy, visit the State Department’s ART and Surrogacy Abroad page for general information regarding U.S. citizenship for the child. 
• Surrogacy in Mexico presents serious risks that must be considered before U.S. citizens begin the surrogacy process.
• If you decide to pursue parenthood in Mexico via ART with a gestational mother, be prepared for possible long delays to document your child’s birth in Mexico and their U.S. citizenship by obtaining a U.S. passport. 
• Ensure you understand Mexican law, which varies by state. The only four states with a legal framework for surrogacy do not permit foreigners and/or same-sex couples to use the procedure. In the other 28 states, surrogacy is largely unregulated.
• In most states, Mexican courts may not enforce surrogacy agreements between non-Mexican or same-sex intending parents and a gestational mother should disputes arise, due to a lack of legal framework for surrogacy. The U.S. Embassy is aware of several cases where surrogacy agencies presented a partial, or false, interpretation of Mexican surrogacy laws.
• In most Mexican states, the gestational mother is the child’s legal parent with full parental rights, and the gestational mother’s name is typically listed on the Mexican state-issued birth certificate. In certain states, a court may amend the birth certificate to remove the name of the gestational mother.
• The U.S. Embassy is aware of cases of foreign nationals, including U.S. citizens, being arrested for attempting to circumvent local law related to surrogacy.

Carbon Monoxide

• Many hotels and other lodgings are not equipped with carbon monoxide detectors, even if they contain sources of this potentially lethal gas. U.S. citizens have died as a result of carbon monoxide poisoning throughout Mexico. If your lodging is not equipped with a carbon monoxide detector, consider traveling with a portable one.

Water Quality: 

• In many areas in Mexico, tap water is not potable. Bottled water and beverages are safe, although you should be aware that many restaurants and hotels serve tap water unless bottled water is specifically requested. Be aware that ice for drinks might be made using tap water.

Altitude: 

• Many cities in Mexico, such as Mexico City, are at high altitude, which can lead to altitude illness. Visit the U.S. Centers for Disease Control and Prevention website for more information about  Travel to High Altitudes .

Adventure Travel

• Participation in adventure sports and activities may not be covered by accident insurance and safety protections and regulations for these activities may differ from U.S. standards.  Visit  our website  and the U.S. Centers for Disease Control and Prevention website  for more information about adventure travel.

General Health

The following diseases are prevalent:

• Typhoid Fever
• Travelers’ Diarrhea
• Chikungunya
• Rocky Mountain Spotted Fever
• Parasitic Infections
• Chronic Respiratory Disease
• Visit the U.S. Centers for Disease Control and Prevention website for more information about Resources for Travelers regarding specific issues in Mexico.   

Air Quality

• Air pollution is a significant problem in several major cities in Mexico. Consider the impact seasonal smog and heavy particulate pollution may have on you and consult your doctor before traveling if necessary.

For further health information, go to:

• U.S. Centers for Disease Control and Prevention  (CDC)

  Private Residential Treatment Facilities: 

• These facilities provide care to U.S. citizens throughout Mexico and include child behavior modification facilities, rehabilitation facilities, and assisted living centers. 
• There is a wide range in standards for education, safety, health, sanitation, immigration, and residency.  Staff licensing may not be strictly enforced or meet the standards of similar facilities in the United States.  
• The State Department has received reports of abuse, negligence, or mismanagement at some of these facilities. U.S. citizens should exercise due diligence and do extensive research before selecting a residential treatment facility.

Travel and Transportation

Road Conditions and Safety:  Motor vehicle accidents are a leading cause of U.S. citizen deaths in Mexico. If you have an emergency while driving, dial “911.” If you are driving on a toll highway (“ cuota ”) or any other major highway, you may contact the Green Angels ( Spanish only ), a fleet of trucks with bilingual crews, by dialing 078 from any phone in Mexico.  Generally, individuals involved in an accident who do not require immediate medical care should contact their insurance providers, who may come to the site to provide an immediate assessment.

Avoid driving on Mexican highways at night. Travel with a charged and functional cell phone capable of making calls in Mexico. Travelers should exercise caution at all times and should use toll (“ cuota ”) roads rather than the less secure free (“ libre ”) roads whenever possible. Do not hitchhike or accept rides from or offer rides to strangers anywhere in Mexico. Travelers encountering police or security checkpoints should comply with instructions.

Road conditions and maintenance across Mexico vary with many road surfaces needing repair. Travel in rural areas poses additional risks to include spotty cell phone coverage and delays in receiving roadside or medical assistance.

Vehicular traffic in Mexico City is subject to restriction Monday through Saturday, according to the license plate number, in order to reduce air pollution. For additional information, refer to the  Hoy No Circula website  ( Spanish only ) maintained by the Mexico City government. See our  Road Safety Page  for more information.  Also, visit  Mexico’s national tourist office website , MexOnline, and Mexico’s customs website  Importacion Temporal de Vehiculos  ( Spanish only ) for more information regarding travel and transportation.

Traffic Laws:   U.S. driver’s licenses are valid in Mexico. Mexican law requires that only owners drive their vehicles or that the owner be inside the vehicle. Failing to abide by this law may lead to impoundment and a fine equal to the value of the vehicle.

Mexican citizens who are not also U.S. citizens or LPRs may not operate U.S.-registered vehicles in Mexico. Mexican insurance is required for all vehicles, including rental vehicles. Drivers involved in accidents, even minor incidents, may be subject to arrest if they are found to be driving without proper insurance, regardless of whether they were at fault. Driving under the influence of alcohol, using a mobile device while driving, and driving through a yellow light are all illegal in Mexico.

If you drive your vehicle into Mexico beyond the immediate border area (approximately 12 miles into Mexico), you must apply for a temporary vehicle import permit with Mexican customs, Banjercito , or at some Mexican consulates in the United States. The permit requires the presentation of a valid passport and a monetary deposit that will be returned to you upon leaving Mexico before the expiration of the permit. Failing to apply for a temporary vehicle import permit may lead to impoundment and a fine equal to the value of the vehicle. 

Vehicles crossing into Mexico must have a valid license plate and registration sticker. Mexican authorities will often refuse to admit vehicles with temporary or paper license plates. Vehicles with expired registration or unauthorized plates will likely be confiscated and the operator could be charged with a fine equal to the value of the vehicle.

The Mission Mexico Vehicle Recovery Unit  assists with the return of stolen U.S. vehicles recovered by Mexican authorities.

If you have an emergency while driving, dial “911.” If you are driving on a toll highway (“cuota”) or any other major highway, you may contact the Green Angels (Spanish only), a fleet of trucks with bilingual crews, by dialing 078 from any phone in Mexico.  Generally, individuals involved in an accident who do not require immediate medical care should contact their insurance providers, who may come to the site to provide an immediate assessment.

Public Transportation/Taxis:  Security on public buses varies throughout the country but is considered a relatively safe transportation option in Mexico City and other major tourist centers. Passengers should protect their personal possessions at all times as theft is common. Intercity bus travel should be conducted during daylight hours in preferably first-class buses using toll roads.

Robberies and assaults on passengers in taxis not affiliated with a taxi stand (known as “libre” taxis) are common. Avoid taking any taxi not summoned by telephone or contacted in advance, including “libre” taxis. When in need of a taxi, telephone a radio taxi or “sitio” (regulated taxi stand) and ask the dispatcher for the driver’s name and the taxi’s license plate number. Application-based car services such as Uber and Cabify are available in many Mexican cities, and generally offer another safe alternative to taxis. Official complaints against Uber and other drivers do occur, however, and past disputes between these services and local taxi unions have occasionally turned violent, resulting in injuries to U.S. citizens in some instances.

See our Road Safety page for more information. 

Aviation Safety Oversight:  The U.S. Federal Aviation Administration (FAA) has assessed the Government of Mexico’s Civil Aviation Authority as not being in compliance with International Civil Aviation Organization (ICAO) aviation safety standards for oversight of Mexico’s air carrier operations. Further information may be found on the  FAA safety assessment page .

Maritime Travel:  Mariners planning travel to Mexico should also check for U.S. maritime advisories and alerts .  Information may also be posted to the  U.S. Coast Guard homeport website , and the NGA broadcast warnings .

If you enter by sea, review the Mexican boating permit requirements  prior to travel or contact the  Embassy of Mexico  in Washington, D.C., for more information.

Maritime Safety Oversight:  The Mexican maritime industry, including charter fishing and recreational vessels, is subject solely to Mexican safety regulations.  Travelers should be aware that Mexican equipment and vessels may not meet U.S. safety standards or be covered by any accident insurance.

Vaccines for Travelers

Vaccines protect travelers from serious diseases. Depending on where you travel, you may come into contact with diseases that are rare in the United States, like yellow fever. Some vaccines may also be required for you to travel to certain places.

Getting vaccinated will help keep you safe and healthy while you’re traveling. It will also help make sure that you don’t bring any serious diseases home to your family, friends, and community.

On this page, you'll find answers to common questions about vaccines for travelers.

Which vaccines do I need before traveling?

The vaccines you need to get before traveling will depend on few things, including:

• Where you plan to travel . Some countries require proof of vaccination for certain diseases, like yellow fever or polio. And traveling in developing countries and rural areas may bring you into contact with more diseases, which means you might need more vaccines before you visit.
• Your health . If you’re pregnant or have an ongoing illness or weakened immune system, you may need additional vaccines.
• The vaccinations you’ve already had . It’s important to be up to date on your routine vaccinations. While diseases like measles are rare in the United States, they are more common in other countries. Learn more about routine vaccines for specific age groups .

How far in advance should I get vaccinated before traveling?

It’s important to get vaccinated at least 4 to 6 weeks before you travel. This will give the vaccines time to start working, so you’re protected while you’re traveling. It will also usually make sure there’s enough time for you to get vaccines that require more than 1 dose.

Where can I go to get travel vaccines?

Start by finding a:

• Travel clinic
• Health department
• Yellow fever vaccination clinic

Learn more about where you can get vaccines .

What resources can I use to prepare for my trip?

Here are some resources that may come in handy as you’re planning your trip:

• Visit CDC’s travel website to find out which vaccines you may need based on where you plan to travel, what you’ll be doing, and any health conditions you have.
• Download CDC's TravWell app to get recommended vaccines, a checklist to help prepare for travel, and a personalized packing list. You can also use it to store travel documents and keep a record of your medicines and vaccinations.
• Read the current travel notices to learn about any new disease outbreaks in or vaccine recommendations for the areas where you plan to travel.
• Visit the State Department’s website to learn about vaccinations, insurance, and medical emergencies while traveling.

Traveling with a child? Make sure they get the measles vaccine.

Measles is still common in some countries. Getting your child vaccinated will protect them from getting measles — and from bringing it back to the United States where it can spread to others. Learn more about the measles vaccine.

Should travelers avoid Mexico as delta surges? For locals who need them, it’s complicated.

‘You need to be conscious. You need to be responsible’

With many of the world’s borders closed or heavily restricted, Mexico has remained one of the most popular destinations for Americans throughout the pandemic thanks to its low barrier of entry. Flights are often affordable, and coronavirus protocols have been manageable.

Destinations such as Cancún, San Jose del Cabo and Mexico City are routinely the most booked international trips for U.S. travelers, and Cancún International Airport reported it exceeded pre-pandemic aerial traffic this summer.

Whether that’s a good thing depends on who you ask.

While vaccinations are becoming more available in Mexico, around 26 percent of the population is fully vaccinated, according to University of Oxford’s Our World in Data . As in the United States, Mexico is experiencing a rise in cases , reporting more than half a million new infections in August. The Centers for Disease Control and Prevention has issued a “Level 3” warning for Mexico, stating only fully vaccinated people should consider travel there. The CDC has the same warning for popular tourist destinations such as Italy, Croatia and Jamaica.

So should Americans avoid travel to Mexico — to protect both themselves and locals? The answer from many locals is more nuanced than a simple yes or no.

You asked: Should I cancel my kids’ end-of-summer trip?

Samantha Martinez, a marketing and commercial director for Hospital Multimédica Norte, located just north of Mexico City, has felt frustrated by Mexico’s loose entry requirements for international visitors compared to those of other countries. Americans do not need to show proof of vaccination or a negative coronavirus test upon arrival — just a health declaration form.

A local's guide to Mexico City

She said she thinks that is part of why Mexico has become such a popular tourist destination during the pandemic, not only for Americans but also visitors from other parts of the world. However, Martinez doesn’t believe those tourists are aware of the reality of the country’s coronavirus battle.

“A couple of weeks ago, we registered the highest peak in the pandemic with more than 24,000 cases per day,” she said. “So the situation in Mexico is not getting any better regarding covid.”

Martinez recognizes the impact of the pandemic on tourism, and tourism’s impact on Mexico. She also understands the need for people to travel. When people ask her if it’s okay to visit Mexico, “my answer depends 100 percent on the responsibility of the tourist,” she said. “You need to be conscious. You need to be responsible. … If you are willing to travel, I think it’s a great idea only if you agree to respect and follow local requirements.”

Fabiola Santiago , who runs mezcal tastings in Santiago Matatlán in Oaxaca, agrees. As someone who splits her time between California and Mexico, she doesn’t want to be hypocritical and tell tourists to stay away, but she also knows that tourism can put local populations at risk.

Santiago recommends any visitors follow masking requirements strictly, particularly if they’re visiting remote communities with limited access to health care.

6 trip ideas from health experts for safer travel this fall

For Vicente Reyes, an Oaxaca native and president of social impact collective Hermano Maguey , which works on promoting an equitable agave ecosystem in the region, if visitors fully vaccinated and get a coronavirus test before their trip, “I would be happy for people to come to Mexico,” he said. “It’s for their own health; they need to know if they have it or not.”

He added: “I think that’s the most responsible for yourself and other people.”

From a travel industry perspective, Americans are welcome to visit Mexico at this time.

“We live and breathe tourism,” said Rodrigo Esponda, the head of the tourism board of Los Cabos, Mexico, where Americans make up 80 percent of visitors. “It’s the only economic engine in the destination.”

Esponda said the delta variant surge hasn’t impacted the region’s tourism outlook yet, and so far this year, visitor numbers have been strong. In July, the Los Cabos region received 25 percent more visitors than in July 2019. The September bookings project the region will outpace 2019 numbers by 20 percent.

Carmen Joaquin, president of the Cozumel Business Owners Union, said because the island relies on cruise visitors, businesses are suffering from reduced tourism numbers, despite having more flights to the island than ever before. Instead of five or six ships a day, the island is getting five or six a week.

“There’s still less income … we used to have 20,000 people coming over in a day,” Joaquin said. “We haven’t been like this for 30 years when cruise ships started booming here.”

Do I need a covid booster shot to travel? 5 things to consider.

In Los Cabos and Cozumel, as well as in many other tourist destinations, there is a push to get the hospitality workforce vaccinated, a move that not only protects employees, but also serves as a selling point for coronavirus-concerned guests. Esponda said 80 percent of adults in Los Cabos are fully vaccinated, and ongoing campaigns are working to increase that number.

Hotels in Mexico have been invested in getting staff immunized, as well.

At the UNICO 20˚87˚ Hotel Riviera Maya, the majority of employees are vaccinated, as well as the employees of the hotel’s subcontractors, such a tour operators and wedding vendors. Frank Maduro, a spokesman for AIC Hotel Group, which represents UNICO 20˚87˚, said the property is very selective about the vaccination status of the companies they work with.

The hotel also offers travel insurance to guests. Should a guest test positive for covid-19 in Mexico, that insurance covers their medical care and extended stay to self-isolate, which has happened.

Maduro recommended that travelers to Mexico look into the health protocols at any accommodation before booking.

“There’s a lot of reputable hotels that take this seriously because this is their life,” Maduro said.

Smaller tourism-driven businesses have also had to take precautions seriously. Graciela Montaño, a chef who teaches cooking classes in Mexico City — and since the pandemic, virtually as well — said she believes travel can be done safely when following common sense protocols. But she doesn’t think travelers should consider Mexico in a vacuum.

“This new virus is all over the world, so thinking about [travel] per country makes no sense because it’s something we are in together,” she said. “It’s not about Mexico or Washington or New York; it’s what you do to feel safe.”

How do I get a coronavirus test abroad?

Since Montaño has resumed her classes during the pandemic, she has adjusted them to have fewer guests at a time, has changed where she takes people for local tastings so they can remain outdoors, and has a masking policy that follows local city protocol.

Sonia Gil, founder of Fluenz , a Spanish-language learning program with immersive experiences in Mexico and Barcelona, has done similar adjustments to her business since reopening after its coronavirus hiatus.

“We were closed for 16 months completely,” Gil said. “The first few months were brutal.”

Gil said that with the delta variant surge, she hopes Fluenz doesn’t have to close again, but she is watching the situation closely. For now, she encourages potential travelers to assess their risk tolerance before deciding to take a trip to Mexico. For those feeling anxious about traveling now, she said, “Wait it out. You don’t have to come now.”

Ultimately, Gil encouraged tourists who are willing to follow local coronavirus regulations and be considerate to locals to visit Mexico.

“I think that we are ready to welcome people as long as they can be respectful and mindful of what’s happening,” she said.

What to Know About Testing and Vaccine Requirements for Travel

Do you need to be vaccinated or have a negative Covid-19 test for your next trip? Check this guide before traveling domestically or abroad.

• Share full article

By Concepción de León

As vaccinations ramp up and regulations loosen for people in the United States, many are planning travel for summer and beyond, with experts predicting that July 4 will be the biggest travel weekend since the beginning of the pandemic.

But with regulations shifting, people might have questions about testing or vaccination requirements for their trips. The Centers for Disease Control and Prevention recently eased travel recommendations to more than 100 countries. On June 18, the European Union added the United States to its “safe list” of countries , meaning that both vaccinated and unvaccinated American travelers should now be able to visit the 27 member countries, but these member states are allowed to set their own requirements and restrictions for travelers.

In the United States, the C.D.C. has advised that vaccinated people no longer need to wear masks in most places and released new travel guidelines that said domestic travel is safe for them. But travelers must take note of local advice and regulations, as these can vary state by state.

Here’s everything you need to consider about testing and vaccinations before you travel within the U.S. or internationally.

Are there testing and vaccination requirements for domestic travel?

For most places, no. You do not need to be vaccinated for any domestic travel. Hawaii is the only state that requires a negative test for travel.

In Hawaii, the test must be administered within 72 hours of arrival and the results uploaded to its Safe Travel platform to avoid a mandatory quarantine when entering the state.

Alternatively in Hawaii, you can also provide proof that you’ve recovered from Covid-19 in the past 90 days, including both a positive test result and a letter from a doctor clearing you to travel.

The state’s governor, David Ige, said this month that people who received their vaccination in the state of Hawaii may bypass testing and quarantine requirements starting on June 15, and that anyone vaccinated in the U.S. will be able to enter Hawaii without testing once the state has reached a 60 percent vaccination rate.

If you are unvaccinated, you should continue to adhere to social distancing and mask-wearing protocols while traveling domestically, the C.D.C. said . You can use the C.D.C.’s Travel Planner to check guidelines by state.

What are the testing and vaccination rules for international travel?

While testing and vaccination requirements vary by destination country, everyone arriving in the U.S. — even vaccinated Americans — must present a negative test result upon entry .

Many nations are still closed to American travelers. Those that are open may require a negative test, proof of vaccination or evidence of recovery (or a combination of these) to enter.

The United Kingdom , for instance, requires that American travelers, regardless of vaccination status, provide proof of a negative test taken within 72 hours of departure, quarantine upon arrival and take two additional tests during their stay. Children under 11 are exempt from these requirements, as are some other people depending on their reason for travel.

Some European countries have been allowing in Americans who are vaccinated or who can show a negative test. Americans are on the European Union’s “safe list” of countries, but while the bloc aims to take a coordinated approach to travel this summer, member states will be allowed to set their own requirements for travelers from individual countries, which could include testing and vaccination.

The E.U. “safe list” also applies to Europe’s border-free Schengen Zone, which includes non-E.U. countries such as Norway, Switzerland, Iceland and Lichtenstein.

Canada is still closed to Americans , with few exceptions, and will remain so until at least early July, said Patty Hajdu, the country’s minister of health, in a news conference in June.

The U.S.-Mexico land border is closed for nonessential travel until at least June 21, but air travel is allowed and the country does not require a negative test for entry. Because of its high risk level, the C.D.C. recommends that travelers be fully vaccinated before traveling to Mexico.

Consult the C.D.C.’s inventory of international travel health notices for more information on regulations by country.

“Travelers should always check with their airline and the embassy of the country they are visiting to ensure they have the proper documentation required to enter the country,” said Perry Flint, a spokesman for The International Air Transport Association, a global airline industry group.

What test should I take, and where and when?

To enter the U.S., travelers must show a negative result to a nucleic acid amplification test (NAAT) — PCR is a type of NAAT test — or an antigen test, also known as a rapid test, taken in the three days before departure, according to the C.D.C .

Some airports offer on-site testing, such as Heathrow Airport in England, or Rome’s Fiumicino International Airport in Italy.

Josh Alexander, a New York-based luxury travel agent for Protravel International, said that many international hotels, including most Four Seasons hotels and resorts , are offering on-site rapid tests for free or at a nominal cost.

Testing at local clinics is also available in many places, though you should check availability at your destination ahead of time and book if you can. It may also come at a high cost. Mr. Alexander said that PCR tests abroad can range from $50 to $150.

The C.D.C. said that it allows for a three-day time frame rather than 72 hours to allow flexibility in the time of day the test can be taken. For instance, if you are flying out on a Friday, the test may be taken at any time on Tuesday.

But, when it comes to international destinations, Mr. Alexander recommends erring on the side of caution when timing your test by calculating it based on time of arrival at your destination.

“Rules are constantly changing,” he said, “so we’re just trying to always tell people they should always be as conservative as possible to eliminate any gray area.”

What are the requirements for minors?

The C.D.C. testing recommendations apply to all children 2 years and older, which means your toddler also needs to deliver a negative Covid-19 test to enter the U.S. from abroad. When traveling, children should wear masks, practice social distancing and wash hands often, the C.D.C. said .

“If the kids are age 12 and older, get ’em vaccinated,” said William Schaffner, an infectious disease expert at Vanderbilt University, in an email.

If you’re traveling to a country within the European Union that is open to travelers from the U.S., children who cannot be vaccinated should have a negative PCR test taken no more than 72 hours before arrival at your destination, and additional testing may be required upon arrival.

Travelers should check with their airline or destination country website for relevant requirements.

What if I want to go on a cruise?

Rules vary from one cruise line to another, with some planning to require that all passengers and crew be vaccinated, and others adopting a hybrid model.

But recent laws passed in Florida and Texas banning businesses from requiring proof of vaccination to use their services may complicate this plan.

Celebrity Cruises, set to be the first U.S. cruise ship to restart operations on June 26 from Fort Lauderdale, Fla., said it’s optimistic that a resolution would be reached in time . It is requiring that guests 16 years and older be vaccinated, while children will be tested at the terminal.

Carnival Cruises said on Monday that its first ship would set sail from the Port of Galveston, in Texas, on July 3 and would be available only for vaccinated passengers. Norwegian, which will begin to operate cruises from Miami in August, said it will require the same through October 31 and has threatened to skip Florida ports if the state does not allow cruise lines an exemption from the law banning vaccine requirements.

Christine Duffy, the president of Carnival Cruise Line, said in a statement on June 7 that “the current CDC requirements for cruising with a guest base that is unvaccinated will make it very difficult to deliver the experience our guests expect, especially given the large number of families with younger children who sail with us.”

“As a result, our alternative is to operate our ships from the U.S. during the month of July with vaccinated guests,” she said.

But even if you are vaccinated, you must also consider the requirements of the country where the cruise is disembarking. The Caribbean island of St. Maarten, for instance, where Celebrity Cruises started sailing on June 5, requires a negative test in addition to proof of vaccination.

What documents should I bring with me if I travel?

This will also depend on where you’re going, but a good rule of thumb is to carry your physical vaccine card, if you have it, and proof of a negative test, if it is required.

Mr. Alexander, the travel agent, recommends people bring the original documents. While a number of digital health certificates — which show vaccine status and test results — are in the works, he said, they are not yet widely accepted. You should check, also, that your document is in the correct language. The United Kingdom , for instance, requires that test results be in English, Spanish or French.

CommonPass , from the Geneva-based nonprofit the Commons Project Foundation, and the I.A.T.A. Travel Pass are two apps providing digital access to vaccine and testing records for travel. The European Union will be releasing its own digital Covid certificate for E.U. citizens by July 1, though it is unclear whether Americans will be able to use it.

You should check with your airline to see if the app you want to use will be accepted at your destination. Both the CommonPass and I.A.T.A. websites list destinations and airline partners accepting the digital health certificates.

Mr. Alexander added that some countries, such as Croatia, may also require proof of a return flight or confirmation of your hotel booking or other accommodation, though this is rare. In South Africa, which has implemented a curfew, travelers may need to show their flight ticket to law enforcement officers to show they are allowed to be in transit.

But these shifting regulations should not dissuade people from traveling, Mr. Alexander said.

“If you’re vaccinated and you’re following safe precautions, you can still have a great experience,” he said.
