The hepatitis E virus (HEV) is the causative agent of hepatitis E. It is of the species Orthohepevirus A. [a] [2] [1] Globally, approximately 939 million corresponding to 1 in 8 individuals have ever experienced HEV infection. About 15–110 million individuals have recent or ongoing HEV infection. [3]
Human, pig, wild boar, sheep, cow, camel, monkey, some rodents, bats and chickens serve as natural hosts. There are two genera in the family. Diseases associated with this family include: hepatitis; high mortality rate during pregnancy; and avian hepatitis E virus is the cause of hepatitis-splenomegaly (HS) syndrome among chickens. [1] [2]
Viral hepatitis is either transmitted through contaminated food or water (A, E) or via blood and body fluids (B, C). The viruses transmitted through water and food are mostly self-limited, resulting in acute illness with full resolution.
A Hepatitis E-like virus has been isolated from a Swedish moose. [7] This virus is quite distinct from the other known Hepatitis E viruses. [3] In total, the genus has four recognized species: Orthohepevirus A, Orthohepevirus B, which was previously known as the avian hepatitis E virus, Orthohepevirus C, and Orthohepevirus D. [3]

All known RNA viruses, that is viruses that use a homologous RNA-dependent polymerase for replication, are categorized by the International ...
