In many parts of the world, hepatitis B virus infects more than 8% of the population. Since blood donors and blood products are tested for HBV, this is no longer the typical means of infection. Reliable blood tests for HBV were developed many years ago. It enters the body through blood-to-blood contact. Hepatitis B virus is found in the blood of people with HBV infection. When treatment is successful, liver scarring and the potential for liver cancer are reduced. Whether treatment will be successful depends on many factors, and these are best discussed with a physician who specializes in liver diseases. Treatment with anti-viral drugs works for some people with HBV who are starting to develop liver damage. Hepatitis B infection is the single most important cause of hepatocellular (liver) cancer. Another concern is the potential for liver cancer.In others, liver disease progresses slowly and does not become a major problem during their lifetime. Some develop severe liver scarring (cirrhosis) within 20 years. However, the speed at which inflammation and scarring take place varies between people. In chronic hepatitis B infection, the liver becomes inflamed and scarred over a period of years.The remaining 90% develop chronic hepatitis B infection. When babies become infected at birth or during infancy, the percentages are reversed - only 10% clear the infection.This persistent state is known as chronic hepatitis B infection. In the other 10%, the immune system cannot clear the virus and hepatitis B infection persists past 6 months, usually for the rest of the person’s life. In 90% of persons who become infected as adults with hepatitis B, the immune system successfully fights off the infection during the acute phase - the virus is cleared from the body within 6 months, the liver heals completely, and the person becomes immune to hepatitis B infection for the rest of their life.Among those who do have symptoms, the illness is usually mild and most people don’t recognize that they have liver disease. During this phase, many people show no symptoms at all.
