There are many types of hepatitis, with both infectious and noninfectious causes. Infectious hepatitis is caused by an infection with a virus, bacteria, fungus, or parasites. The most common type of infectious hepatitis is viral hepatitis, which describes hepatitis caused by an infection with one of several hepatitis viruses. Viral hepatitis includes five main types:
Hepatitis A: Hepatitis A is caused by the hepatitis A virus (HAV). This type of hepatitis is spread easily through contact with stool or blood of an infected person. This can occur through contaminated water and food, sexual contact, or shared intravenous needles. The hepatitis A virus causes acute infections that are often mild, typically resolving without treatment within several weeks. Highly effective vaccines are available to prevent hepatitis A.
Hepatitis B: Hepatitis B is caused by the hepatitis B virus (HBV). Hepatitis B can be spread through contact with an infected person`s blood or certain other body fluids, including transmission from a mother to her baby. This virus can cause either acute or chronic infections. Highly effective hepatitis B vaccination is available to prevent infection.
Hepatitis C: Hepatitis C is caused by the hepatitis C virus (HCV). The hepatitis C virus is spread through exposure to the blood of a person with this infection, often through the use of injectable drugs and during birth to a mother with an HCV infection. This virus can cause both acute and chronic infections. Currently, there is no vaccine to prevent hepatitis C; however, it is treatable.
Hepatitis D: Also known as delta hepatitis, hepatitis D is caused by the hepatitis D virus (HDV). This virus is unique in that it only infects people who already have the hepatitis B virus. HDV is spread through the blood or other body fluid of an infected person, most often from sharing needles and unprotected sex with a person who has this infection. Hepatitis D can be either acute or chronic. The vaccine for hepatitis B can prevent hepatitis D because only those infected with hepatitis B can contract HDV.
