What is viral hepatitis?
• Answer: Hepatitis means inflammation of the liver. Viral hepatitis is inflammation of the liver caused by a virus. There are five identified types of viral hepatitis and each one is caused by a different virus. In the United States, hepatitis A, hepatitis B and hepatitis C are the most common types. Hepatitis A is caused by hepatitis A virus (HAV), hepatitis B is caused by hepatitis B virus (HBV), and hepatitis C is caused by hepatitis C virus (HCV).
The term “hepatitis” means inflammation of the liver and viral hepatitis refers to a collection of viruses that can affect the liver. There are three main hepatitis viruses: hepatitis A, B and C. Because many of the same behaviors that put one at risk for HIV and STDs can also transmit viral hepatitis, the STD/AIDS Prevention Branch has a Viral Hepatitis Education and Prevention Program to raise awareness about viral hepatitis.
