MOEI participants must take full responsibility for health cover and health insurance throughout the duration of the programme.

In Thailand, the MOEI programme takes place in a malarial zone during the rainy season when the risk of infection is generally high. Dengue fever is also a real possibility, and MOEI Thailand registered cases in both 2008 and 2009. Although both Mae Sot and the refugee camps that MOEI works in are relatively clean, all participants must consult a doctor well in advance of joining the MOEI programme and must follow the medical advice they are given.

In the centre of Mae Sot there is a good hospital that can be accessed on a self-paying basis. There are also clinics in Mae Sot and in the refugee camps where some participants will teach.
