Types Of Hepatitis A To E

Types Of Hepatitis A To E


Hepatitis is inflammation of the liver. Several different viruses cause viral hepatitis. They are named the hepatitis A, B, C, D, and E viruses.

All of these viruses cause acute, or short-term, viral hepatitis. The hepatitis B, C, and D viruses can also cause chronic hepatitis, in which the infection is prolonged, sometimes lifelong.

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


Symptoms include
  • jaundice (yellowing of the skin and eyes)
  • fatigue
  • abdominal pain
  • loss of appetite
  • nausea
  • diarrhea
  • vomiting.
  • However, some people do not have symptoms until the disease is advanced.

Hepatitis A


Disease Spread 


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 with an infected person; and, during outbreaks, day care children and employees, sexually active gay men, and injection drug users.

Prevention 


The hepatitis A vaccine; also, avoiding tap water when traveling internationally and practicing good hygiene and sanitation.

Treatment 


Hepatitis A usually resolves on its own over several weeks.

Hepatitis B


Disease Spread 


Through contact with infected blood, with an infected person, and from mother to child during childbirth.

People at Risk


Injection drug users, children of immigrants from disease-endemic areas, people who live with an infected person, infants born to infected mothers, health care workers, and hemodialysis patients.

Prevention 


The hepatitis B vaccine.

Treatment 


Drug treatment with alpha interferon or lamivudine.

Hepatitis C



Disease Spread 


Primarily through contact with infected blood; less commonly, through sexual contact and childbirth.

People at Risk


Injection drug users, hemodialysis patients, health care workers, people who have live with an infected person, people who have multiple partners, infants born to infected women, and people who received a transfusion of blood or blood products before July 1992 or clotting factors made before 1987.

Prevention 


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.

Treatment 


Drug treatment with alpha interferon or combination treatment with interferon and the drug ribavirin.

Hepatitis D


Disease Spread 


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 live with a person infected with hepatitis D or if they live with an infected person.

Prevention 


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).

Treatment 


Drug treatment with alpha interferon.

Hepatitis E


Disease Spread


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 with an infected person.

Prevention 


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.

Treatment 


Hepatitis E usually resolves on its own over several weeks to months.
