Hepatitis E is not contagious after cure. First of all, the source of infection and transmission of hepatitis E is similar to that of hepatitis A. The source of infection is mainly patients in the acute stage and hidden infected people, and the number of the latter is often far more than that of the former. The source of infection can be transmitted by fecal-oral route, when the patient’s feces contaminate drinking water, food, vegetables, toys and so on, it can cause outbreaks and epidemics of the disease. Therefore, when hepatitis E is cured, the patient is unable to excrete the virus and contaminate the environment, and it is even more unlikely that the possible virus will be transmitted to susceptible people. As the source of hepatitis E infection in daily life is mostly hidden infection, we need to pay attention to the problem of personal hygiene in daily life and avoid eating in food establishments with unqualified hygiene quality, so as to avoid the infection triggered by incomplete disinfection. In addition, we can also choose hepatitis E vaccine for preventive vaccination to reduce the risk of hepatitis E infection in the future. However, before receiving the vaccine, you need to be clear about the contraindications related to the vaccine, those who are allergic to the components of the vaccine need to be prohibited from receiving the vaccine, and patients with acute active diseases need to be suspended from receiving the vaccine.
