Positive IgG antibody to hepatitis E virus indicates infection with hepatitis E virus, and follow-up of IgG antibody titer in the outpatient clinic of the Department of Infectious Diseases is recommended. If there are no symptoms such as fatigue, loss of appetite, nausea, vomiting, abdominal distension, jaundice and so on do not need to be hospitalized. 1. Viral hepatitis E is mostly caused by eating contaminated food or water. It is a self-limiting infection and usually resolves spontaneously in 4 to 6 weeks. Only a few will develop into fulminant hepatitis and acute liver failure, which is life-threatening. 2. There is no specific treatment for hepatitis E. Prevention is the most effective control method. Clinical isolation, general treatment (avoiding cross-infection, light diet, rest), symptomatic treatment (reduced glutathione to protect the liver, bicyclic alcohol to reduce enzymes, ursodeoxycholic acid to reduce bilirubin) are the mainstays, avoiding the use of drugs that cause liver damage. 3. For prevention, recombinant hepatitis E vaccine can be given. The use of drugs should be under the guidance of the doctor, patients with any discomfort to the hospital in time to improve the examination.
