The presence of HBeAg in individuals with hepatitis indicates_______________?
Show answer Hide answer
Answer: C. High infectivity
Explanation
Hepatitis B e antigen is a viral protein secreted into the bloodstream during active replication. Its presence indicates that virus particles are actively assembling and multiplying within hepatocytes. High circulating viral loads correlate directly with increased risk of transmitting the infection. Hepatitis B virus is a circular partially double-stranded DNA virus affecting the liver. Serological panels test for surface antigens, core antibodies, and e antigens to stage infections. HBeAg seroconversion to corresponding antibodies usually indicates receding viral replication activity.
Identifying HBeAg status helps physicians assess patient infectivity and monitor antiviral treatment efficacy. Pregnant mothers positive for HBeAg require specialized interventions to prevent vertical transmission. Public health screening relies on these serological markers to manage hepatitis B carrier states. Simple carriers typically harbor low viral loads and often test negative for HBeAg. Late convalescence is characterized by declining antigen levels and the appearance of protective antibodies. Carrier status alone does not guarantee high infectivity unless active viral replication is present.
