报告摘要：
Hepatitis B virus (HBV) infection remains a serious public health problem in china. In this talk, I will first introduce the three national serosurvey data of hepatitis B in China. Then I will talk about an age-structured discrete model of HBV Transmission and the method of parameter estimation. Based on this HBV Transmission model, we evaluate the independent impact of newborn hepatitis B vaccination on reducing HBV prevalence in China and explore the influence of increasing test-and-treat coverage on HBV infection. We also estimate the effect of sexual transmission on HBV infection in China. We find that newborn hepatitis B vaccination in China have played the most important role in reducing HBV prevalence. Increasing test-and-treat coverage will significantly reduce HBV infection in China, especially in the middle-aged people and older people. Sexual transmission has become the main way of transmission of new HBV infections in China, especially for men. This is a joint work with Dr. Miaolei Li, Peifeng Liang and Guihua Zhuang.
