Do I need immunizations to enter China
Travelers are advised to check with their doctors before visiting China. A Health Declaration form must completed upon arrival. No immunizations are required for short-term travelers, unless you are coming from or through a yellow fever infected area. The Centers for Disease Control and Prevention (CDC) in Atlanta, USA, recommends those who have traveled from an infected area to have vaccination records available. Anyone not having the above mentioned certificate will be detained for observation for as long as six days. You should also bring any special health remedies or medications you require, as well as over-the-counter items. For traveling into the countryside, immune globulin is also recommended to combat hepatitis A, as is typhoid immunization. Travel to high-altitude areas such as Tibet is not recommended for those with pulmonary or heart problems.
The health quarantine service has the right to prevent any foreigner suffering from AIDS, venereal disease, leprosy, mental illness, or active tuberculosis from entering China.
