• Patients with acute hepatitis B (AHB) usually present after developing symptoms; therefore, the temporal kinetics of viral markers during the incubation period have not been documented clearly. We describe an AHB infection before the onset of hepatitis, throughout the course of the disease and without anti-viral therapy. The patient initially visited our hospital for immunization against HBV and was found to be positive for viral markers: 0.0 IU/mL of anti-HBs, 0.06 S/CO of anti-HBc and 2.93 IU/mL of HBsAg. During the 14 days after his first visit, HBsAg, HBV DNA, HBe antigen and HBV core-related antigen, but not anti-HBc or anti-HBs, levels increased. On day 22, he developed acute hepatitis. The period of logarithmic viral replication was estimated to be 7.0 days. HBV genomic sequencing and phylogenetic analysis indicated transmission from the patient’s wife. Although sexual intercourse could not be ruled, another possible route of transmission was the unusual occurrence of kissing his wife when she had macroscopic bleeding after tooth brushing, 2 months before his positive HBsAg result; the day of the episode being consistent with the calculated HBV replication velocity. This study reveals the temporal kinetics of viral markers during the incubation period of AHB.
