There are no mandatory vaccines to enter El Salvador, but there are recommendations depending on your origin and type of trip. This guide sums up the usual advice and health tips so you can enjoy your trip safely. If this is your first trip to El Salvador, take note of these recommendations.

Recommended Vaccines

• Routine vaccines up to date: MMR, tetanus, etc., as per your country schedule.
• Hepatitis A: recommended due to food and water; very common in travel guides.
• Typhoid: sometimes recommended if you will be in rural areas or eating a lot of street food.
• Dengue: there is no vaccine universally recommended for everyone; in tropical areas there are mosquitoes. Use repellent, long sleeves and trousers at dusk and in green areas. If you have high fever and joint pain, see a doctor.

Always check with a travel health clinic or your doctor before the trip; they will tell you what you need based on your history and itinerary.

Water and Food

• Water: drink bottled or boiled water; avoid tap water where you are not sure.
• Food: typical food is safe in places with good hygiene. Avoid ice of uncertain origin and raw vegetables you cannot wash yourself. In established restaurants and comedores the risk is low.

Dengue and Mosquitoes

In El Salvador dengue exists and, in some seasons, zika or chikungunya. Reduce bites with repellent (DEET or icaridin), clothing that covers at dusk and a mosquito net if you sleep with the window open in mosquito-heavy areas. No vaccine is required to enter; prevention is key.

Basic First Aid Kit

Bring what you normally use: painkillers, anti-diarrhoea, antihistamine, repellent, sunscreen. Check our packing guide for more details. If you take regular medication, bring enough and in hand luggage. Good travel insurance covers emergencies and prescribed medicines.

Summary

No mandatory vaccines; it is wise to have hepatitis A and routine vaccines up to date, and to protect yourself from dengue with repellent and clothing. Bottled water and food in clean places reduce risk. When in doubt, see a travel medicine specialist.
