Hepatitis C virus
A single-stranded RNA virus in the Flaviviridae family that causes hepatitis C. Abbreviated HCV. The HCV genome contains some 10,000 nucleotides and encodes a single polyprotein of 3,000 amino acids. HCV was discovered in 1989. Before that time, hepatitis C was referred to as non-A, non-B hepatitis.
- Hepatitis D
Liver inflammation due to the hepatitis D virus (HDV), which causes disease only in patients who additionally have the hepatitis B virus. Transmission occurs via infected blood, needles, or sexual contact with an infected person. Symptoms are identical to those of hepatitis B. HDV infection can be prevented with the hepatitis B vaccine and through […]
- Hepatitis D, E, F, and G
Lesser known (than hepatitis A, B, and C), the most significant of these seems to be type D, or the delta agent, which only causes disease in the presence of the hepatitis B virus.
- Hepatitis E
A rare form of liver inflammation caused by infection with the hepatitis E virus (HEV). It is transmitted via food or drink handled by an infected person or through infected water supplies in areas where fecal matter may get into the water. Hepatitis E does not cause chronic liver disease. There is no vaccine or […]
- Hepatitis F
It was formerly believed that a virus isolated from rare blood samples was able to cause hepatitis, and this virus was designated hepatitis F virus. Further investigation has failed to confirm the existence of this virus. There is no known hepatitis F virus.
- Hepatitis G
A virus isolated from the blood of some patients with posttransfusion hepatitis that is hypothesized to be a cause of hepatitis by some investigators, but the virus has not yet been confirmed as a cause of acute or chronic hepatitis.
