Hepatitis B is a contagious liver condition caused by the hepatitis B virus. It can be transmitted from one person to another through blood-to-blood contact. Infected women can also transmit the infection to their babies.
During the initial phase of the disease, which is called acute hepatitis B infection, many individuals do not experience any symptoms, according to the San Francisco Department of Public Health. About 90 percent of those who become infected as adults fight off the acute hepatitis B infection. The virus is eliminated from the body within six months. This makes these individuals immune to hepatitis B. In babies, it is the opposite case. Only 10 percent infected children manage to resist the condition at the acute phase.
