Hepatitis B is a viral disease transmitted by exposure to infected blood or blood products (such as blood transfusions), saliva, or through unprotected sex with someone who is infected.[1]
As with AIDS, Hepatitis B is not contagious from casual contact, however Hepatitis B is a resilient virus which can live outside the body for up to seven days under certain conditions[2] as opposed to HIV which can only survive outside the body for a few hours[3].
