There are no special requirements of short-term travelers with the exception of those coming from or via an infected area. All visitors may be asked to complete a health form to indicate if they have symptoms of yellow fever, cholera, typhoid, or other communicable diseases. Those planning on staying in China for a period of over six months may be required to present medical records.
Although the government has made every effort to improve people's health, China still has some basic health problems and in many cases primitive sanitation. Don't drink tap water, nor eat raw vegetables and fruit unless they've been washed in a chlorine solution. Diarrhea is common for travelers who are unaccustomed to the new diet and water.
In winter, the dry air may cause sinus problems, skin dryness, and problems for contact lens wearers. Bring along a well-stocked medical kit and any prescription drugs you will require.
In China, urban and rural medical services differ a lot from each other. If traveling in the countryside, there may be no appropriate medical services beyond primary health care. Some hospitals in cities have special sections for foreigners and English is spoken there. Doctors may be found in many of the large hotels in China. Payment must be made on the spot for treatment, medicine and transport. If planning to visit areas outside of Beijing, Shanghai, Guangzhou and Hong Kong, emergency evacuation insurance is advised.
