报告简介：

Although great progress has been made in the prevention and mitigation of TB in the past 20 years, China is still the third largest contributor to the global burden of new TB cases, accounting for 833,000 new cases in 2019.Improved mitigation strategies, such asvaccines, diagnostics, and treatment, are needed to meet goals of WHO. Given the huge variability in the prevalence of TB across age groups in China, the vaccination, diagnostic techniques and treatment for different age groups may have different effects. Moreover, the data of TB cases show significant seasonal fluctuations in China.In this talk, I presenta non-autonomous differential equation model with age structure and seasonal transmission rate. Our resultsshowthat vaccinating susceptible individuals whose ages are over 65 and between 20 and 24 is much more effective in reducing prevalence of TB.Although the improved strategies will significantly reduce the incidence rate of TB, it is challenging to achieve the goal of WHOby2050.
