The intracellular replication process of HBV is modeled based on the molecular biological findings.
The effect of recycling of HBV virion for the replication dynamics of HBV is investigated.
Two replication patterns names “arrested” and “explosive” replication are clarified.
The threshold for the explosive replication is lowered by recycling of HBV virion.
Small release rate of virion in HBV replication process may be risk factor for the exacerbation of hepatitis during the long time course of chronic hepatitis.
