is a liver disease caused by the hepatitis A virus (HAV). Hepatitis
A can affect anyone. In the United States, hepatitis A can occur
in situations ranging from isolated cases of disease to widespread
epidemics.

Hepatitis
B: is a serious disease caused by a virus that attacks
the liver. The virus, which is called hepatitis B virus (HBV),
can cause lifelong infection, cirrhosis (scarring) of the liver,
liver cancer, liver failure, and death. |

Hepatitis
C: is a liver disease caused by the hepatitis C virus
(HCV), which is found in the blood of persons who have the disease.
HCV is spread by contact with the blood of an infected person. |
 |
Hepatitis
D: is a liver disease caused by the hepatitis D virus
(HDV), a defective virus that needs the hepatitis B virus to
exist. Hepatitis D virus (HDV) is found in the blood of persons
infected with the virus. |
 |
Hepatitis
E: is a liver disease caused by the hepatitis E virus
(HEV) transmitted in much the same way as hepatitis A virus.
Hepatitis E, however, does not occur often in the United States. |
