Summary

Infections with viral hepatitis A through E have a variable clinical presentation ranging from asymptomatic or mild flulike symptoms to jaundice and fulminant liver failure. Hepatitis A and E are fecal-orally transmitted, resulting in acute infection that is mostly self-limited.

Testing for hepatitis A through E is based on serological and molecular tests.
