Fig. 1From: Evaluating the independent influence of sexual transmission on HBV infection in China: a modeling studyFlow chart of the HBV transmission model. The total population was divided into three compartments: Susceptible individuals (\( {S}_a^g(t) \)), Chronic HBV infections (\( {C}_a^g(t) \)), and Recovered cases (\( {R}_a^g(t) \)). The acutely infectious individuals (\( {A}_a^g(t) \)) were considered to be in a transient process. The force of infection involved three transmission patterns: sexual transmission, perinatal infection and blood transmissionBack to article page
