Despite active efforts to eradicate the disease, malaria remains a threat in some parts of Thailand — especially for travelers heading into jungles or border zones. Below are the latest updates on risk areas and protection advice for summer 2025.
Where Infection Risk Still Exists
The highest number of cases is reported in nine provinces along Thailand’s borders with Myanmar, Cambodia and Malaysia: Tak, Mae Hong Son, Kanchanaburi, Phetchaburi, Ubon Ratchathani and Chiang Rai. The main transmission zones are rural and forested areas near international borders.
Government Measures and Prevention Programs
Thailand continues its national malaria elimination strategy. Early detection systems, preventive medication and medical support in remote villages help reduce spread. New-generation drugs are now widely used against all strains of the parasite.
Some provinces have already been declared malaria-free, but the situation remains delicate in border and jungle areas. Tourist hubs like Bangkok, Pattaya, Phuket and Koh Samui carry minimal to no risk.
Traveler's Guide to Malaria Prevention
- Consult your doctor before travel — you may need preventive medication.
- Avoid high-risk areas if you have a weak immune system or chronic health issues.
- Use insect repellents and wear full-body clothing, especially at night.
- Sleep under mosquito nets and avoid stagnant water during jungle stays.
- If symptoms appear — fever, chills, headache, muscle pain — seek medical help immediately.
Conclusion
Thailand has made major progress toward malaria elimination, but in 2025 it still poses a risk in certain border and forested provinces. Travelers planning deep trips or jungle tours should be informed and cautious. Taking preventive measures is key to a safe and comfortable trip.
