Hepatitis is inflammation of the liver.
Other viruses may also cause hepatitis, but they have yet to be discovered and they are obviously rare causes of the disease.
Symptoms of Viral Hepatitis
- jaundice (yellowing of the skin and eyes)
- abdominal pain
- loss of appetite
- low grade fever
However, some people do not have symptoms.
Primarily through food or water contaminated by feces from an infected person. Rarely, it spreads through contact with infected blood.
People at Risk
International travelers; people living in areas where hepatitis A outbreaks are common; people who live with or have sex with an infected person; and, during outbreaks, day care children and employees, men who have sex with men, and injection drug users.
The hepatitis A vaccine; also, avoiding tap water when traveling internationally and practicing good hygiene and sanitation.
Hepatitis A usually resolves on its own over several weeks.
Through contact with infected blood, through sex with an infected person, and from mother to child during childbirth.
People at Risk
People who have sex with an infected person, men who have sex with men, injection drug users, children of immigrants from disease-endemic areas, infants born to infected mothers, people who live with an infected person, health care workers, hemodialysis patients, people who received a transfusion of blood or blood products before July 1992 or clotting factors made before 1987, and international travelers.
The hepatitis B vaccine.
Acute hepatitis B usually resolves on its own. Very severe cases can be treated with lamivudine.
Primarily through contact with infected blood; less commonly, through sexual contact and childbirth.
People at Risk
Injection drug users, people who have sex with an infected person, people who have multiple sex partners, health care workers, infants born to infected women, hemodialysis patients, and people who received a transfusion of blood or blood products before July 1992 or clotting factors made before 1987.
There is no vaccine for hepatitis C; the only way to prevent the disease is to reduce the risk of exposure to the virus. This means avoiding behaviors like sharing drug needles or sharing personal items like toothbrushes, razors, and nail clippers with an infected person.
Acute hepatitis C: treatment is recommended if it does not resolve within 2 to 3 months.
Through contact with infected blood. This disease occurs only in people who are already infected with hepatitis B.
People at Risk
Anyone infected with hepatitis B: Injection drug users who have hepatitis B have the highest risk. People who have hepatitis B are also at risk if they have sex with a person infected with hepatitis D or if they live with an infected person. Also at risk are people who received a transfusion of blood or blood products before July 1992 or clotting factors made before 1987.
Immunization against hepatitis B for those not already infected; also, avoiding exposure to infected blood, contaminated needles, and an infected person's personal items (toothbrush, razor, nail clippers).
Through food or water contaminated by feces from an infected person. This disease is uncommon in the United States.
People at Risk
International travelers; people living in areas where hepatitis E outbreaks are common; and people who live or have sex with an infected person.
There is no vaccine for hepatitis E; the only way to prevent the disease is to reduce the risk of exposure to the virus. This means avoiding tap water when traveling internationally and practicing good hygiene and sanitation.
Hepatitis E usually resolves on its own over several weeks to months.
Other Causes of Viral Hepatitis
Hope Through Research
The National Institute of Diabetes and Digestive and Kidney Diseases, through its Division of Digestive Diseases and Nutrition, supports basic and clinical research into the nature and transmission of the hepatitis viruses, and the activation and mechanisms of the immune system. Results from these studies are used in developing new treatments and methods of prevention.

The National Digestive Diseases Information Clearinghouse (NDDIC) is a service of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). The NIDDK is part of the National Institutes of Health under the U.S. Department of Health and Human Services. Established in 1980, the clearinghouse provides information about digestive diseases to people with digestive disorders and to their families, health care professionals, and the public. NDDIC answers inquiries, develops and distributes publications, and works closely with professional and patient organizations and Government agencies to coordinate resources about digestive diseases.
Publications produced by the clearinghouse are carefully reviewed by both NIDDK scientists and outside experts.
