Understanding where hepatitis B originates helps clarify how it is distinct from other forms of viral hepatitis. The hepatitis B virus (HBV) is not new — it has likely infected humans for thousands of years, with origins tracing back to ancient primates. Unlike hepatitis A, which spreads through contaminated food or water, HBV is transmitted through direct contact with infected blood or bodily fluids. And unlike hepatitis C, HBV is a DNA virus and has a vaccine. This guide explains the origins of HBV, its transmission cycle, and how it differs from hepatitis A and C.
