The hepatitis B virus can lead to liver damage and even death. Hepatitis B is generally considered to be an adult disease because it's known to be transmitted through unsafe sex and shared needles. But up to 40 percent of those who get it, including children, don't engage in these "high-risk" behaviors and experts don't know how they got infected. Before the vaccine was introduced in the United States, there were about 25,000 cases a year in young children; only 6,000 of them got it from their mother at birth.
