Hepacivirus is a genus of viruses in the family Flaviviridae. The most well-known and studied species of this genus is the Hepatitis C virus (HCV), which is a major cause of hepatitis worldwide. Other species in this genus are known to infect horses, rodents, and bats.

Taxonomy[edit | edit source]

The Hepacivirus genus includes several species, the most well-known of which is the Hepatitis C virus. Other species include Hepacivirus A, Hepacivirus B, and Hepacivirus C, among others.

Structure and Genome[edit | edit source]

Hepaciviruses are enveloped, positive-sense single-stranded RNA viruses. The genome of hepaciviruses is approximately 9.6 kilobases in length and encodes a single polyprotein that is processed into individual viral proteins.

Pathogenesis[edit | edit source]

The most well-known and studied hepacivirus, the Hepatitis C virus, is a major cause of hepatitis, cirrhosis, and liver cancer worldwide. Other hepaciviruses are known to cause disease in animals. For example, Hepacivirus A is known to cause respiratory disease in horses.

Treatment and Prevention[edit | edit source]

Treatment for Hepatitis C virus infection has improved significantly in recent years with the development of direct-acting antiviral drugs. However, there is currently no vaccine available for Hepatitis C or any other hepacivirus. Prevention strategies primarily involve reducing the risk of exposure to the virus.
