Viral Hepatitis
Viral Hepatitis: Introduction
Viral hepatitis is a general name for several forms of hepatitis that are caused by a virus. Viral hepatitis is the most common type of hepatitis, a group of serious diseases that cause inflammation of the liver and liver damage. Viral hepatitis is often called infectious hepatitis, and the viruses that cause it are contagious and can be passed from person to person.
Other less common forms of hepatitis are called noninfectious hepatitis. In noninfectious hepatitis, inflammation of the liver and liver damage are not due to a viral infection. Causes of noninfectious hepatitis include obesity, alcoholism (alcoholic hepatitis), genetic and metabolic disorders, immune-related injury (autoimmune hepatitis), or effects of medications or exposure to toxins (toxic hepatitis).
Viral hepatitis includes hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E. Each of these types of viral hepatitis are caused by the hepatitis virus of the same name, such as the hepatitis A virus. The most common forms of viral hepatitis in the U.S. are hepatitis A, hepatitis B, and hepatitis C.
All types of viral hepatitis cause inflammation of the liver. The liver is a vital organ, and normal functioning of the liver is crucial to health and life. Viral hepatitis can reduce the liver's ability to do its vital job in helping the body to fight infection, stop bleeding, clear the blood of toxins, store energy, produce healthy blood, digest food and remove waste.
There are differences in the way that the various forms of viral hepatitis are passed from person to person and how they progress. General risk factors for catching viral hepatitis include being sexually active outside of a monogamous relationship, living in or travelling to places with poor sanitation, being an IV drug abuser who shares needles, or using dirty needles for tattooing or body piercing.
Symptoms of viral hepatitis also differ between individuals depending on such variables as the specific type of viral hepatitis, age, medical history, the presence of complications and general health. Symptoms common to viral hepatitis include flu-like symptoms, fever, headache, nausea, muscle aches and jaundice, a yellowing of the skin and whites of the eyes. Complications can be serious, even life-threatening, and include the development of chronic hepatitis, cirrhosis, and increased risk of liver cancer, and liver failure. For more information on symptoms and complications, refer to symptoms of viral hepatitis.
Making a diagnosis of viral hepatitis includes performing a complete medical evaluation and history and physical examination. This includes questioning about risk factors for contracting viral hepatitis. Diagnostic blood tests include tests that can check for the viruses that cause viral hepatitis. Liver function tests are blood tests that can help to determine the level of severity of viral hepatitis by checking level of functioning of the liver and if there is any damage to the liver.
Imaging tests that create a picture of the liver and may be performed in some cases include an ultrasound, CT, and/or a nuclear liver scan.
It is possible that a diagnosis of viral hepatitis can be missed or delayed because symptoms can be vague or there may be no symptoms in some people in some forms of the disease. For more information on misdiagnosis, refer to misdiagnosis of viral hepatitis.
Treatment of viral hepatitis includes rest and ensuring good nutrition. For serious cases, especially if there is liver damage, hospitalization may be necessary. Treatment in the hospital may include medications, a liver biopsy, and other diagnostic testing and treatment. For more information on treatment, refer to treatment of viral hepatitis. ...more »

Article Excerpts about Viral Hepatitis
Hepatitis is inflammation of the liver. Several different viruses
cause viral hepatitis. They are named the hepatitis A, B, C, D, and
E viruses.
All of these viruses cause acute, or short-term, viral hepatitis.
The hepatitis B, C, and D viruses can also cause chronic hepatitis,
in which the infection is prolonged, sometimes lifelong.
