Risk is present in forested and hilly areas mainly towards the international borders, all year round. There is low to no risk in the cities of Bangkok, Chiang Mai, Chiang Rai, Pattay and Phuket, the islands of Ko Samui and Ko Chang and the River Quai bridge area.

Malaria precautions are essential. Avoid mosquito bites by covering up with clothing such as long sleeves and long trousers especially after sunset, using insect repellents on exposed skin and, when necessary, sleeping under a mosquito net.

Prophylaxis: Since mefloquine resistance is now common, Atovaquone/proguanil OR doxycycline is usually advised for those visiting the borders with Cambodia and Myanmar. For all other border areas, Atovaquone/proguanil OR doxycycline OR mefloquine is advised throughout the year.

If you have been travelling in a malarious area and develop a fever seek medical attention promptly. Remember malaria can develop even up to one year after exposure. If travelling to high risk malarious areas, remote from medical facilities, carrying emergency malaria standby treatment may be considered.
