Hepatitis E is inflammation of the liver caused by infection with the hepatitis E virus (HEV); [4] [5] it is a type of viral hepatitis. [6] Hepatitis E has mainly a fecal-oral transmission route that is similar to hepatitis A , although the viruses are unrelated.
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]
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]
Notable human diseases caused by RNA viruses include influenza, SARS, MERS, COVID-19, Dengue virus, hepatitis C, hepatitis E, West Nile fever, Ebola virus disease, rabies, polio, mumps, and measles. All known RNA viruses, that is viruses that use a homologous RNA-dependent polymerase for replication, are categorized by the International ...
Hepatitis D is a defective virus that requires hepatitis B to replicate and is only found with hepatitis B co-infection. [17] In adults, hepatitis B infection is most commonly self-limiting, with less than 5% progressing to chronic state, and 20 to 30% of those chronically infected developing cirrhosis or liver cancer. [ 31 ]
Hepatitis E is caused by the Hepatitis E virus (HEV), from the family Hepeviridae. It produces symptoms similar to hepatitis A , although it can take a fulminant course in some patients, particularly pregnant women (mortality rate about 20%); chronic infections may occur in immune-compromised patients.
HBeAg is a hepatitis B viral protein, produced by the HBcAg reading frame. It is an indicator of active viral replication ; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
