The presence of HBsAg, anti-HBc and often HbeAg is characteristic of what phase of hepatitis?

The presence of HBsAg (Hepatitis B surface antigen), anti-HBc (antibody to hepatitis B core antigen), and often HBeAg (Hepatitis B e antigen) is indeed indicative of the early acute phase of Hepatitis B virus (HBV) infection. During this phase, HBsAg is detectable as the virus replicates in the liver, marking the active infection. The appearance of anti-HBc suggests that the body is beginning to mount an immune response against the virus. HBeAg, indicating higher viral replication, may also be present, particularly in cases with a high viral load.

In the context of chronic HBV infection, while HBsAg would still be present, you would expect anti-HBc to be predominantly IgG rather than IgM, and HBeAg would not always be detected since the disease can present in a stable or inactive carrier state.

Resolved HBV infection is characterized by the presence of anti-HBs (antibody to hepatitis B surface antigen) and the absence of HBsAg, meaning that in this phase, the person has cleared the virus and developed immunity.

Acute HAV (Hepatitis A virus) infection does not relate to the markers of HBV infection, as
