  Precautions Certificate Needed
Yellow Fever No 1
Cholera 2 No
Typhoid and Polio 3 No
Malaria 4 No
1) Travellers over 1 year of age who come from infected areas need a yellow fever vaccination certificate. Countries and areas included in endemic zones are considered to be infected areas.

2) According to World Health Organisation guidelines issued in 1973, a cholera vaccination certificate is not a condition of entry to Thailand. However, cholera is a risk and precautions are extremely necessary. Seek the most current advice before deciding whether these precautions should include vaccination, as medical opinion is divided over its effectiveness; see the Health appendix.

3) Vaccination against typhoid is recommended.

4) Malaria risk occurs throughout the year in remote parts of all over Thailand, particularly in forested and hilly regions and around the border areas. There is little risk in cities including the major tourist areas, e.g. Bangkok, Chiang Mai, Pattaya, Phuket and Samui. The malignant falciparum form still exists and is said to be very resistant to chloroquine and to sulfadoxine-pyrimethamine. Resistance to mefloquine and to quinine has been reported from the parts of areas around the borders with Myanmar (Burma) and Cambodia.

Food & drink

Food and water-borne diseases are a common occurrence. Boiled water or water in bottle is recommended for drinking, brushing teeth or making ice. Milk that is not pasteurised should be boiled; however, there is pasteurised or homogenised milk available at most supermarkets. Tinned or powdered milk is safe when it is reconstituted with sterile water. Avoid dairy products that may have been made with unboiled milk. Fish and meat should have been cooked, especially served hot, but not reheated. Avoid unpeeled fruit and raw vegetables.

Other risks

Amoebic and bacillary dysentery
and hepatitis A and E occurs. Hepatitis B is common while trachoma is also present.

Japanese encephalitis
occurs, especially in remote regions. There is a vaccine available, and visitors are strongly advised to consult their doctor before their departure. Visitors should take the precaution to prevent mosquito bites because of the risk of this disease and dengue fever. Always use repellant.

HIV infection is common, particularly among hookers in Bangkok and Chiang Mai.

Bengal Cholera has rarely been reported.

Rabies still exists and for those at high risk, a vaccination prior to arrival must be considered. Seek immediate medical advice if you are bitten.


Visitors who are suspected or confirmed of having AIDS will not be allowed to enter Thailand.

Health Care

Health insurance is recommended. Medical facilities are good in main cities. All major hotels have doctors on call
