Contact your GP around 8 weeks before your trip to check whether you need any vaccinations or other preventive measures. Country specific information and advice is published by the National Travel Health Network and Centre, and useful information about healthcare abroad, including a country-by-country guide of reciprocal health care agreements with the UK, is available from NHS Choices.
Medical care is generally good in major cities, though some hospitals can be very crowded. Outside major cities, the standard of healthcare is variable. Healthcare is not provided free of charge in China and medical bills can be high. Medical evacuation from China is very expensive. Make sure you have comprehensive travel insurance covering healthcare for the duration of your stay.
The high levels of air pollution in major urban and industrialised areas in China may aggravate bronchial, sinus or asthma conditions. Children, the elderly and those with pre-existing medical conditions may be especially affected. You can check the pollution index levels for many cities on the aqicn.info website.
It is not unusual for guests to consume large quantities of strong alcohol served at business dinners in China. On rare occasions this has led to severe illness or even death. Fake alcohol is also sometimes sold in bars; this can be more damaging to the health than genuine products.
Tap water in China is generally not safe to drink. You should drink only bottled water.
The extreme altitude (over 3,000m) in some mountainous areas of China, including Tibet, parts of Xinjiang-Uighur Autonomous Region and Qinghai Province, may cause altitude sickness.
The Chinese authorities react quickly to any outbreaks of any infectious disease, including enforcing quarantine for those showing symptoms. There are occasional incidents of influenza transmitted to humans from animals, notably birds and pigs. Outbreaks are usually confined to rural areas and infection is believed to arise from close contact with infected birds or animals. For more information see the NaTHNaC website.
If you need emergency medical assistance during your trip, dial 120 and ask for an ambulance. Ambulances can be slow to arrive and may not have trained responders. You should contact your insurance/medical assistance company promptly if you are referred to a medical facility for treatment.
