报告题目:An age-structured-like model for non-Markovian sexually transmitted diseases on the coupled network
报告摘要:Sexually transmitted infections (STIs) have caused significant public health burden globally. In most models of STIs spreading in networks, it is assumed that the transmission and recovery processes are Markovian processes; that is, the transmission and recovery times per event are exponentially distributed. However, both transmission and recovery times per event for many real STIs do not completely follow exponential distribution. In this talk, allowing for general transmission and recovery times distributions, we propose a general Edge-Based Age-structured-like Compartmental Model for STIs in a coupled configuration network. We consider sexual transmissions between men with also heterosexual contacts. The obtained system is a coupled system of ODE and PDE. We study the existence and non-negativity of solutions, the epidemic threshold R0, the global stability of disease-free equilibrium with R0 < 1 and the final epidemic size. Our results provide excellent guidance to develop appropriate prevention and control strategies.
