Hepatitis E: guidance, data and analysis

Hepatitis E virus (HEV) usually produces mild disease but in rare cases it can prove fatal, particularly in pregnant women.

Hepatitis E is an illness of the liver caused by hepatitis E virus (HEV), a virus which can infect both animals and humans.

HEV infection usually produces a mild disease, hepatitis E. However, disease symptoms can vary from no apparent symptoms to liver failure, and in rare cases, it can prove fatal, particularly in pregnant women.

In individuals with suppressed immune systems, the virus can cause persistent infection which can lead to chronic inflammation of the liver.
