Disease/Condition Glossary
Hepatitis B: Hepatitis B is a potentially fatal liver infection caused by the hepatitis B virus (HBV). It is highly contagious (spreads from one person to another) and spreads by intimate contact with an infected individual, direct contact with infected blood, use of a contaminated needle, use of an infected razor/other personal objects, or transmission from mother to baby during birth. The virus can survive outside the body for up to 7 days. Chronic hepatitis B develops slowly, and symptoms may not be obvious until complications arise. Hepatitis B symptoms might occur three months after being exposed to the infection and can continue for two to twelve weeks. Chronic hepatitis B consequences include liver failure, liver cancer, and liver cirrhosis (scarring). Hepatitis B can be prevented by taking the vaccination.
