Those who carry such special articles as microorganisms, human body tissues, biological products, and blood and its products, should declare to a quarantine department, and subject these articles to quarantine inspections. Passengers from yellow fever-infested areas should, when entering China, display to the quarantine department effective certificates showing that they have been inoculated against yellow fever. He who does not have such a valid certificate shall be retained for observation for six days beginning from the day he left the infested area, or he shall be inoculated and retained until the certificate comes into effect. It is the task of the Chinese quarantine authorities to prevent foreigners suffering AIDS, venereal diseases, leprosy, mental diseases and open tuberculosis from entering China.  

There are no particular immunizations required for entry into China, unless the traveler is coming from a yellow fever infected area. The Canadian and US disease control and prevention authorities recommend the all travelers have current polio and tetanus immunizations. For traveling into the countryside and remote areas, immune globulin is also recommended to combat hepatitis A, as is typhoid immunization. It is very important that you consult your own doctor or local clinic for more information.  We advise you to bring along a supply of antibiotics, an anti-diarrhea agent, and any other prescription drugs required by your current medical conditions.
