As with any international relocation, the medical dangers in Thailand differ from those in the UK. The primary risk factor is contracting an illness from a mosquito bite. Some of the precautions you can take include: • Taking malaria tablets before you travel. • Sleeping under a malaria net. • Wearing long sleeves and trousers. • Drinking bottled water. The other significant risk is with air pollution in the cities, which can be particularly harmful to people with respiratory conditions. You should wear a suitable pollution-filtering mask during commutes if living in bigger cities, especially in Bangkok.
