Mexico Travel Health

Reviewed by Alexander Webber, Chief Epidemiologist · Updated 2026-08

Mexico presents a moderate to high health risk for travelers depending on destination. Dengue, Zika, and chikungunya are endemic throughout coastal and tropical lowland regions, while highland cities like Mexico City carry minimal mosquito-borne disease risk. Food and waterborne illnesses including hepatitis A, typhoid, and traveler's diarrhea are common risks nationwide. Geographic variation is significant: resort corridors in Cancun and Los Cabos carry lower risk than rural southern states like Chiapas and Oaxaca.

Malaria Risk

Present in rural areas of Chiapas, Oaxaca, Guerrero, Sinaloa, and Nayarit states. Primarily chloroquine-sensitive P. vivax. Urban areas, tourist resorts, and the Yucatan Peninsula are considered low risk.

Food and Water Safety

Moderate Risk Tap water: not safe to drink

Avoid raw vegetables washed in tap water, unpasteurized dairy, and street food from vendors without access to running water. Stick to bottled or treated water including for brushing teeth.

Key Health Tips for Mexico

  • Drink bottled or purified water throughout Mexico, including resort areas.
  • Use DEET-based repellent in coastal and jungle regions where dengue mosquitoes are active.
  • Seek care immediately for fever within 2 weeks of return — dengue and malaria require specific testing.
  • Altitude sickness is a risk above 2,400 meters — allow 2 to 3 days to acclimatize in Mexico City.
