Explanation:
Detailed explanation-1: -Viral shedding persists for 1 to 3 weeks. Infected persons are most likely to transmit HAV 1 to 2 weeks before the onset of illness, when HAV concentration in stool is highest. The risk then decreases and is minimal the week after the onset of symptoms.
Detailed explanation-2: -HBcAg (core antigen) is a hepatitis B viral protein. It is an indicator of active viral replication; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
Detailed explanation-3: -Hepatitis B core antigen (HBcAg) cannot be detected in serum, but the antibody against it can. During acute infection, anti-HBc is predominantly of IgM class.
