Infectious hepatitis is most often caused by a virus. There are four commonly known hepatitis viruses, hepatitis A, B, C and D. Other hepatitis can be caused by bacteria, although less often. Still other forms of hepatitis are not caused by infectious agents at all, but by injury from toxins (such as alcohol, work chemicals, pollution, etc.) or other injury to the liver.
A group of viruses known as the hepatitis viruses cause most cases of liver damage worldwide. Hepatitis can also be due to toxins (notably alcohol), other infections or from autoimmune process. It may run a subclinical course when the affected person may not feel ill. The patient becomes unwell and symptomatic when the disease impairs liver functions that include, among other things, removal of harmful substances, regulation of blood composition, and production of bile to help digestion.
Hepatitis B is a contagious liver infection caused by hepatitis B virus. There is Hepatitis B virus in the blood and body fluids of infected persons. The disease can be transmitted through blood, semen, vaginal fluids, and many other body fluids. These are some examples of how it can be transmitted into the body: Blood transfusions, contact with blood in health care settings, had direct contact with the blood of an infected person by touching an open wound or being stuck with a needle, had unprotected sex with an infected person, received a tattoo or acupuncture with contaminated material, shared needles during drug use, shared personal items (such as toothbrushes, razors, and nail clippers) with an infected person
