The Hepatitis E virus is the causative agent of Hepatitis E. Its taxonomic name is Orthohepevirus A.
Virology
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[1] but was only molecularly cloned in 1990.[2]
Taxonomy
It was previously classified in the Caliciviridae family. However, its genome more closely resembles the rubella virus. It is now classified as a member of the genus Orthohepevirus in the Hepeviridae family.[3]
