The rate of mortality from preventable and treatable diseases (such as Dengue fever, malaria, TB) among the migrant population is substantially higher than that for the rest of the Thai population. The FED health team is also often called to assist migrants who have been injured at work. Chemical burns, lacerations, and broken bones caused by accidents on construction sites are all common. Recently, there has been a spate of attacks on Burmese people, including knife attacks, beatings and rape. In addition, HIV infections are increasing among the migrant population in Thailand. People living with HIV/AIDS are often unaware of their status until they become very ill.
