A hybrid model for hepatitis B virus*

The hepatitis B virus (HBV) is a kind of pandemic infectious disease. It is becoming a major health problem in Asian and African countries, however, less so in other areas around the world. There is a vast background for studying HBV. However, some problems still require further study. For example, when the patient is infected by HBV, how to arrange the treatment schedule? Using long term continuous treatment or others? Therefore, we wish to readdress the study of HBV. First, we propose a new hybrid model that contains both continuous and discrete variables. Second, we analyze its dynamical behavior. We hope that this study may provide some new insight for HBV disease and some new guidance for the therapy.
