The term “hepatitis” is conventionally reserved for “viral hepatitis” as most cases of hepatitis are caused by one of the five liver-specific (hepatotropic) viral agents: hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV), and hepatitis E virus (HEV). All these human hepatitis viruses are RNA viruses except for HBV, which is a DNA virus. Other rare causes of hepatitis include infections with cytomegalovirus, Epstein-Barr virus, and herpes simplex virus, toxic chemicals, medication overdose, and autoimmune hepatitis.
