Most diseases in China are treatable. SARS has recently shown that the health care system might need some readjustment. However, the foreigner is treated well if they become ill. The foreign needs to be aware that HIV/AIDS has become a greater issue and care should be taken in personal hygiene and sexual conduct. SARS is also an issue if it again reoccurs and the foreign teacher should always follow the instructions of the host institution as they try to combat the virus. This may mean that the foreigner at times feels restricted in movement and ability to perform duties. However, precautions are with good reason and the foreign teacher should try not to question the procedures, but simply follow instructions.
As mentioned, malaria is not a true danger. Tuberculosis is found in the rural areas and among migrant workers.
The foreign teacher should practice good hygiene, be aware that there are diseases that exist in China that perhaps no longer openly exist elsewhere, and pay attention to where they are and what they are experiencing.
