Hepatitis is one of the prominent health problems. Many illnesses and conditions can cause inflammation of the liver, for example, autoimmune Hepatitis. Hepatitis is most often viral, due to infection with one of the hepatitis viruses (A, B, C, D, and E) or another virus (such as those that cause infectious mononucleosis, cytomegalovirus disease, or yellow fever). The main non viral causes of hepatitis are alcohol and drugs.

It can cause a wide number of symptoms ranging from general malaise to lifelong infection, cirrhosis of the liver, liver cancer, liver failure, and death. HBV spreads by contaminated body fluids, such as blood, saliva, semen, vaginal fluids, tears, and urine, an infected blood transfusion, shared infected needles or syringes for injecting drugs, sexual activity with an HBV-infected individual, and transmission from HBV-infected mothers to their newborn infants.

Hepatitis C virus
