Hepatitis E is known as viral hepatitis E. Viral hepatitis E is an acute infectious disease caused by hepatitis E virus infection, which is contracted through viral infection, food contamination and blood contact. 1. Viral infection: Hepatitis E virus is mainly transmitted through fecal-oral transmission, and infection with the virus can cause acute liver injury. 2. Food contamination: Eating food contaminated by hepatitis E virus is easy to get viral hepatitis E. Food contamination can lead to widespread infection, and the speed of infection is very fast. 3. Blood contact: Injection of blood and plasma containing hepatitis E virus can also lead to hepatitis E virus infection. The incubation period of hepatitis E virus is from ten days to sixty days, and the onset is rapid. After infection, jaundice, fever, generalized weakness, nausea and other symptoms may appear. Viral hepatitis E is self-limiting and will not turn into chronic hepatitis, and secondary infection is rare. If infection occurs, one should consult a doctor in time for a clear diagnosis and active treatment.
