Health
Use normal traveler hygiene: drink sealed or treated water if unsure, be selective with street food, and wash hands. Mosquito-borne dengue, Zika and chikungunya occur; use repellent and screened/air-conditioned rooms, especially in warm/coastal areas. Malaria risk is limited to certain areas. Mexico City and some colonial/highland destinations are high altitude, so pace early days. Heat, sun, beach currents and seasonal storms can be practical risks.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. CDC advises being up to date on routine vaccines, including MMR, polio, flu, varicella, Tdap, shingles where applicable, plus COVID-19. Hepatitis A is recommended for unvaccinated travelers; hepatitis B and typhoid are commonly considered. Rabies pre-exposure vaccine depends on animal-exposure risk and access to care. Chikungunya vaccine may be considered for extended stays. Malaria medication is only for certain areas and should be discussed with a clinician. Yellow-fever vaccine is not recommended and no certificate is required for Mexico.
eSIM / connectivity
eSIM is widely usable in major cities and tourist corridors if your phone is unlocked and eSIM-compatible. Mexico’s main mobile networks are Telcel, AT&T Mexico and Movistar; AT&T Mexico and Movistar publish consumer eSIM activation options, including prepaid/app or online/store flows. Many international travel eSIMs are data-only and roam on Mexican networks; confirm coverage for rural areas before relying on one.
