+HBeAG indicates?

• A. Low infectivity
• B. Immunity
• C. Carrier state
• D. +High degree of potential infectivity

Answer: (D)

HBeAg, or hepatitis B e antigen, is a protein secreted when HBV is actively replicating. Its presence in blood reflects high levels of viral replication, which means the person is highly infectious and can transmit the virus more readily to others. This marker is not about immunity—that’s indicated by anti-HBs—and it isn’t the sole determinant of a carrier state, since people can be carriers with varying replication activity. When the immune system suppresses replication, HBeAg often becomes negative and anti-HBe appears, signaling lower infectivity. So a positive HBeAg points to a high degree of potential infectivity.
