ABCs of Hepatitis
Hepatitis A is inflammation (irritation and swelling) of the liver from the hepatitis A virus. The hepatitis A virus is found mostly in the stools and blood of an infected person about 15 - 45 days before symptoms occur and during the first week of illness. Because not everyone has symptoms with hepatitis A infection, many more people are infected than are diagnosed or reported.
Hepatitis B is irritation and swelling (inflammation) of the liver due to infection with the hepatitis B virus (HBV). Hepatitis B infection can be spread through having contact with the blood, semen, vaginal fluids, and other body fluids of someone who already has a hepatitis B infection.
Hepatitis C is a viral disease that leads to swelling (inflammation) of the liver. Hepatitis C infection is caused by the hepatitis C virus (HCV). Most people who were recently infected with hepatitis C do not have symptoms.
