Hepatitis B virus (HBV) is most commonly transmitted through blood that is positive for HBeAg. HBeAg is a marker of active viral replication and indicates a high level of infectiousness. When blood is positive for HBeAg, it means that the person is highly contagious and can easily transmit the virus to others. Therefore, this is the most likely mode of transmission for Hepatitis B.
