Hepatitis A:
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. |
