This page contains the main health risks for travellers and general recommendations. Travel conditions are different for everyone and each patient's health condition varies. Discuss your trip during a travel consultation with your doctor or in a travel clinic, preferably six to eight weeks before departure.

Important health risks

There is a high risk of malaria along the border with Myanmar in the west. We recommend the use of mosquito-repellent measures from dusk till morning, in combination with the use of malaria tablets.

There is a moderate malaria risk in the area around Tak and on the island of Little Ko Chang on the border with Myanmar. We recommend the use of mosquito-repellent measures from dusk till morning. For people with an increased risk, we sometimes recommend preventive malaria tablets, or taking an emergency treatment with you.

There is a low malaria risk in the rest of the country. We recommend the use of mosquito-repellent measures from dusk till morning.

There is no malaria risk in Bangkok, Chiang Mai, Chiang Rai and Pattaya.

In case of fever during or after your journey, get tested for malaria as soon as possible.

Insects can transmit diseases such as dengue, chikungunya, zika and leishmaniasis.

Protect yourself against insects.

Japanese encephalitis occurs all over the country year-round. The peak season is between May and October and especially in the north.
