The patient no longer has acute hepatitis B infection as evidenced by the absence of HBsAg and anti-HBc IgM. The presence of anti-HBc total and anti-HBs indicates past exposure to hepatitis B and immunity, respectively. The absence of anti-HAV IgM and anti-HCV antibodies rules out acute hepatitis A and C infections. Therefore, the patient is in the convalescent phase of hepatitis B infection.
