Thailand – Health Risks, Inoculations, Vaccinations, and Health Certificates

Thailand is one of the most popular travel destinations in Southeast Asia, welcoming millions of visitors every year. While the country has much to offer, it is important to be aware of potential health risks before travelling. In this article, we will explore the common health risks in Thailand, vaccination and inoculation requirements, and where to get reliable advice on health risks.

Common Health Risks in Thailand

Mosquito-borne diseases

Mosquito-borne diseases are prevalent in Thailand and can be a serious health risk. The most common mosquito-borne diseases in Thailand are dengue fever, chikungunya, and Zika virus. Symptoms of these diseases include fever, headache, joint pain, and rash.

To minimize the risk of mosquito-borne diseases, travellers should take measures to avoid mosquito bites, such as wearing long-sleeved shirts and pants, using mosquito repellent, and staying in accommodations with screens on doors and windows. Travellers should also be aware of the symptoms of these diseases and seek medical attention if they experience any of them.

Food and water-borne illnesses

Travellers to Thailand should also be aware of the risk of food and water-borne illnesses, such as diarrhoea, hepatitis A, and typhoid fever. These illnesses can be contracted through contaminated food or water.
