Abstract
Hepatitis A and B viruses were identified a long time ago, but cases of hepatitis without markers of infection by these viruses have been described around the world. Molecular biology methods have been used to study other viruses involved in non-A, non-B hepatitis cases. Two agents have been associated with these cases, one parenterally transmitted (Hepatitis C Virus) and other enterically transmitted (Hepatitis E Virus). The hepatitis E virus (HEV) is a single strand RNA virus, shaped spherical and was primarily defined as a Caliciviridae member, but because of some phylogenetic diversity between these agents, HEV has not been classified yet. Hepatitis epidemic and outbreak transmitted by fecal-oral route had been described since 1950, but the identification was possible only in 1991. In this paper, we show an update about Hepatitis E Virus infection around the world, with a special focus on Brazil.
