Hepatitis B is one of several viruses that causes the liver to become infected.
Most people fight off the infection themselves.
There are over a million carriers of the hepatitis B virus in the United States and an estimated 200,000 people contract this serious liver disease each year. People exposed to blood or body fluids of an infected person are at risk. Most people who get Hepatitis B have no recognizable signs or symptoms. The only way the disease can be positively identified is through a blood test. Many people are surprised to learn when they have donated blood that they test positive for the virus.
