Entry & Exit Requirements
U.S. citizens must have a valid passport to enter Mexico. Passports must be valid for at least the duration of your stay. As this requirement is subject to change at any time without notice, we recommend at least 6 months’ validity. A passport card is not acceptable for entry to the U.S. by air.
If you are not traveling with a U.S. passport, please check with the Mexican Embassy for the requirements based on your nationality.
Health Information
IMMUNIZATIONS
The Centers for Disease Control recommends that all travelers be up to date on routine vaccinations such as measles-mumps-rubella (MMR) vaccine, diphtheria-pertussis-tetanus vaccine, varicella (chicken pox) vaccine, and your yearly flu shot before every trip.
There are no vaccinations required for entry into Mexico.
Though not required, the CDC does recommend vaccination against hepatitis A, hepatitis B, and typhoid for most unvaccinated travelers to Mexico.
Please consult your physician for additional information and recommendations based on your individual circumstances.
Malaria & other Insect-borne Illnesses
The CDC warns that travelers to certain regions of Mexico, including the Yucatán Peninsula, may be at risk for exposure to malaria. Malaria is caused by a parasite found in Anopheles mosquitos, which are active from dusk until dawn. The CDC recommends that travelers take precautions to avoid mosquito bites. To protect against mosquitos and other biting insects, cover exposed skin with lightweight, long-sleeved shirts and pants, consider treating clothes with permethrin, and use an insect repellent containing an active ingredient like DEET or picaridin. Apply sunscreen first, followed by the repellent (preferably 20 minutes later). If you choose to use an anti-malarial drug, please consult your physician.
The CDC also warns that dengue fever is a potential risk in Mexico. In addition, locally transmitted cases of Zika virus and chikungunya have previously been reported. As there are currently no vaccines available for these illnesses, follow the mosquito avoidance guidelines listed above. As a precaution, the CDC advises women who are pregnant to consider postponing travel to any area where Zika virus transmission is ongoing.
Cases of Rocky Mountain spotted fever, a tick-borne illness, have been reported in the Yucatán Peninsula. To protect against tick bites, follow the measures above. After spending time outdoors in grassy or wooded areas, the CDC recommends showering and conducting a full-body check for ticks. If you find a tick attached to your skin, safely remove it as soon as possible.
Travelers’ diarrhea
The CDC warns that travelers’ diarrhea is the most common travel-related illness. Consumption of contaminated food and water may cause diarrhea. To avoid this, do not drink tap water, and use bottled water to brush your teeth. Avoid ice and uncooked vegetables or fruit without a peel. When in doubt, ask your guide. Restrict yourself to cooked food at restaurants, and avoid food sold on the streets. If you contract diarrhea, it is very important to drink large quantities of purified water. Consult your doctor for appropriate medication should you contract diarrhea.
Some people are extremely sensitive and may get diarrhea simply because of dietary changes. If you are prone to gastrointestinal issues, consult your physician or nutritionist for preventative measures.
SUN EXPOSURE
The effects of the sun can be damaging to the eyes and skin. Spending time outdoors exposes you to the sun’s harmful ultraviolet (UV) rays, even on cloudy days. To protect yourself from the sun, use a broad spectrum sunscreen of at least SPF 15, protect skin with clothing, wear a wide-brimmed hat and sunglasses, and drink plenty of fluids.
