Hepatitis A virus is a nonenveloped, icosahedral capsid (spherical shape) with single-stranded RNA genome. It belongs to the Picornaviridae family.

Orally transmitted, the virus may cause local infections of the intestinal epithelium, and then, after a short viraemic episode, attacks the liver, where it replicates and finally triggers hepatitis.

The main transmission paths is direct or indirect contact with contaminated persons or objects.
