Properly handle epidemic areas, isolate patients, adopt effective treatment methods for known hepatitis viruses, strengthen the management of catering and child care industries, strictly test blood donors, and strictly control any possible sources of infection. In daily life, we should strengthen food hygiene, prevent feces from polluting domestic water, strengthen the management of production, supply and sale of blood and blood products, and the catering industry should disinfect public tea sets, tableware, towels, haircuts, pedicures and dental instruments. We advocate the use of disposable syringes, one needle and one tube per person. All blood collection needles, surgical instruments, scraping needles, probes, endoscopes and acupuncture needles in the laboratory should be disinfected by one person to prevent iatrogenic infection. Block mother-to-child transmission. Educate the whole people to improve their physical fitness, improve their ability to resist diseases, and form the habit of stressing hygiene. Wash your hands with running water before and after meals, do not drink raw water, do not eat raw aquatic products, and do not eat unclean and expired food. Do a good job in self-protection of susceptible people.
