Context Most Pages Skip
Hepatitis B is a viral infection that attacks the liver. Unlike hepatitis A, which is always acute and resolves on its own, hepatitis B can become a long-term, chronic condition. The virus is transmitted through blood and body fluids, similar to hepatitis C. The seriousness of hepatitis B depends largely on the age at infection and the person's immune response. While many adults fight off the virus, infants and young children are at high risk of chronic infection, which can silently damage the liver over decades.
