Travel smart to Mexico with health and immunisation in mind

Why health planning matters for travel

Travelling to Mexico can be an enriching experience for holidays, work, study, or visiting family. Thoughtful health planning supports a smoother journey and reduces avoidable disruption. Most travel health considerations relate to common infections, routine immunisation gaps, food and water hygiene, insect exposure, altitude, and access to medical care rather than rare or extreme risks. A calm, evidence-based approach allows you to prepare confidently and enjoy your trip.

Common illnesses travellers may encounter

Across Mexico’s cities, coastal regions, and rural areas, common respiratory and gastrointestinal infections occur year-round. Colds, influenza, COVID-19, and viral gastroenteritis account for most travel-related illness. Exposure risk increases in airports, buses, markets, festivals, accommodation, and crowded tourist settings. Most illnesses are mild, but prevention remains worthwhile, particularly when travel involves frequent movement between regions.

Immunisation and routine protection

Before departure, it is important to ensure routine vaccinations are current. This usually includes measles, mumps, rubella, diphtheria, tetanus, pertussis, polio, varicella, influenza, and COVID-19.
For many travellers to Mexico, additional vaccines such as hepatitis A and typhoid are strongly recommended due to food and water exposure risks. Hepatitis B may be discussed depending on length of stay and planned activities. Rabies vaccination is sometimes considered for travellers spending time in rural areas, working with animals, or undertaking adventure travel where access to urgent medical care may be limited. Immunisation advice should always be individualised through discussion with your GP.

Food, water, and everyday hygiene

Food and water hygiene is one of the most important contributors to travel wellbeing in Mexico. Drinking bottled, boiled, or properly treated water and avoiding ice of uncertain origin reduces illness risk. Choosing food that is freshly cooked and served hot, peeling fruit yourself, and practising regular hand hygiene help prevent gastrointestinal infection. Allowing time for meals, hydration, and rest supports energy and comfort during travel.

Insect exposure and environmental factors

Mosquito-borne illnesses such as dengue, Zika, and chikungunya are present in parts of Mexico. Using insect repellent, wearing protective clothing, and choosing screened or air-conditioned accommodation reduce exposure.
Some regions, including Mexico City, are at higher altitude. Travellers may notice shortness of breath, fatigue, or headaches on arrival. Gradual adjustment, hydration, and pacing activities help most people adapt comfortably.

Managing existing health conditions

If you live with a chronic medical condition, advance planning is essential. Carry enough medication for your entire trip in original packaging, along with copies of prescriptions and a brief medical summary if needed. Changes in routine, heat, altitude, and long travel days can affect sleep, blood glucose control, pain levels, and fatigue. Planning ahead supports continuity of care and reduces stress if illness occurs while overseas.

Medical care, insurance, and preparation

Medical facilities are generally good in major cities but may be limited in rural areas. Comprehensive travel insurance, including cover for emergency evacuation, is strongly recommended. Carrying a basic medical kit with essentials such as oral rehydration salts, pain relief, and anti-diarrhoeal medication can help manage minor illness promptly.

When to speak with your GP before travel

A GP appointment six to eight weeks before departure allows your immunisation status, health history, medications, and itinerary to be reviewed together. This discussion focuses on preparation rather than restriction and supports safe, informed travel planning.
