Overview
Taxonomy
Viruses; ssRNA viruses; ssRNA positive-strand viruses; Hepeviridae; Hepevirus; Hepatitis E virus[1]
Biology
The viral particles are 27 to 34 nanometers in diameter, are non-enveloped and contain a single-strand of positive-sense RNA that is approximately 7300 bases in length. The virus particle was first visualised in 1983[3] but was only molecularly cloned in 1990.[4]
It was previously classified family Caliciviridae. However, its genome more closely resembles the rubella virus. It is now classified in a new virus family, named as Hepeviridae.
- Caused by the Hepatitis E virus (HEV)
- HEV is found in the stool (feces) of persons and animals with hepatitis E.
- HEV is spread by eating or drinking contaminated food or water.
- Transmission from person to person occurs less commonly than with hepatitis A virus
- Most outbreaks in developing countries have been associated with contaminated drinking water. [3]
