What Causes Hepatitis? continued...

Other viruses. Other viruses may also cause hepatitis. These include the Epstein-Barr virus (often associated with mononucleosis), the varicella virus (which causes chickenpox), the herpes simplex virus (HSV), and cytomegalovirus ( CMV).

Although viruses are the most common cause of hepatitis, other causes include autoimmune liver disease, obesity, alcohol, toxins, or misuse of certain prescription drugs and over-the-counter drugs such as Tylenol. These forms of hepatitis can cause the same symptoms and liver inflammation that result from viral hepatitis, but are not contagious.
