How many types of viral hepatitis are there, and can all be spread via sexual contact?
At least five different viruses specifically attack the liver leading to viral hepatitis. They are known by alphabetical names: hepatitis A through hepatitis E. When infection with one of these viruses causes inflammation of the liver, the resulting condition is known as viral hepatitis. Four other viruses, hepatitis F ( probably nonexistent) , hepatitis G, the transfusion-transmitted virus (TTV), and S.E.N.-V (S.E.N. are the initials of the person in whom the virus was first isolated; “v” stands for virus) may also specifically attack the liver, but are not associated with significant acute or chronic hepatitis. Other viruses, such as herpes simplex virus and Epstein-Barr virus, can also attack the liver. However, since the liver is not the principal organ damaged by these viruses, they are not considered hepatitis viruses. HAV and HEV are transmitted by the enteric or fecal-oral route. Enteric transmission consists of introduction of a virus into the body by way of the digestive trac
