报告摘要：Sexually transmittedinfections (STIs) have caused significant public health burden globally. Inmost models of STIs spreading in networks, it is assumed that the transmissionand recovery processes are Markovian processes; that is, the transmission and recoverytimes per event are exponentially distributed. However, both transmission andrecovery times per event for many real STIs do not completely followexponential distribution. In this talk, allowing for general transmission andrecovery times distributions, we propose a general Edge-BasedAge-structured-like Compartmental Model for STIs in a coupled configurationnetwork. We consider sexual transmissions between men with also heterosexualcontacts. The obtained system is a coupled system of ODE and PDE. We study theexistence and non-negativity of solutions, the epidemic threshold R0, theglobal stability of disease-free equilibrium with R0 < 1 and the finalepidemic size. Our results provide excellent guidance to develop appropriateprevention and control strategies.
