Viral hepatitis is one of five infectional factors cause early death in all over the world. Every day at least one million people die because of viral hepatitis. Six hepatitis viruses have been known until now. They are A, B, C, D, E, G, and it is probable that at least two other kinds i.e. F, and H, will be known soon. Only hepatitis B is a DNA virus, and the others are RNA viruses. All viruses (B, C, D, G) are coated and distributed by eating and drinking, except A, and E, which are uncoated and are distributed by blood and its derivations. The most common cause of acute viral hepatitis in Iranian adults is HBV. Infection due to hepatitis B virus is a global issue and it is estimated that more than two billion people in the world have some witnesses of being involved by this virus, through serological tests.
