There are three major types of hepatitis in the U.S. -- A, B, and C. Each one affects your liver, an organ in your belly that's about the size of a football.
They're all contagious, but you can take steps to protect yourself.
The risk of having chronic infection is related to the age at which you first become infected. The risk is highest for newborns infected at birth and children up to age 5.
Many people who have chronic hepatitis B won't develop complications. But about 15 to 25 out of 100 people who have chronic infection will die of cirrhosis or liver cancer.1 (This means that 75 to 85 people out of 100 who have a chronic infection won't die of these diseases.) Having a lot of virus in the body (a high viral load) increases the risk of getting cirrhosis and liver cancer.
You are more likely to get cirrhosis if you carry a certain hepatitis B antigen, are older than 40, and have high liver enzymes. For more information, see the topic Cirrhosis.
Risk factors for getting liver cancer after chronic infection include being male, having a family history of liver cancer, being over 40 years old, having cirrhosis, and also having hepatitis C.
People who have hepatitis B who engage in high-risk behavior (such as having multiple sex partners or injecting illegal drugs) are at increased risk for hepatitis C. They also are at higher risk of getting HIV, the virus that causes AIDS.
