China Travel Health Advice
A yellow fever vaccination certificate is required from travellers coming into China from infected areas. There is a risk of malaria throughout the low-lying areas of the country, and it is recommended that travellers to China seek medical advice about malaria before departure. Vaccinations are recommended against hepatitis A and hepatitis B, typhoid (not necessary if eating and drinking in major restaurants and hotels), Japanese encephalitis (usually only recommended for rural areas), and rabies (only recommended for travellers at risk of animal bites). Tap water shouldn't be drunk unless it has first been boiled, filtered or chemically disinfected. Street food should be treated with caution.
There is generally a high standard of health care in major Chinese cities, but it is not provided free of charge; travellers are advised to have comprehensive travel health insurance.
