报告题目：Dynamical Behaviors of an Almost Periodic SVEIR Warning Model in a Patchy Environment
报告摘要：Prevention and control of infectious diseases is one of the important public health issues faced by countries around the world. The outbreak of infectious diseases is the result of a combination of various factors, including seasonal factor, individual movement between different regions leading to spread, non-pharmaceutical interventions (NPIs) and effectiveness and availability of vaccines, all of which are important factors in disease transmission and outbreaks. Taking these key conditions into consideration, an almost periodic SVEIR warning model in the patch environment is proposed. Firstly, by means of the reproductions numbers, our results implies that the effective reproductions numbers , the disease gradually disappears; when , the disease spreads and leads to local outbreaks. Secondly, the relationship between and , is given by numerical simulation. The numerical results show that even if all people are vaccinated, non-drug interventions are still crucial due to the low efficacy of vaccines. Furthermore, the numerical results suggest that even after vaccination, non-drug interventions and increased vaccine effectiveness are needed to achieve herd immunity. The establishment of this model effectively explains the transmission mechanism of most infectious diseases, providing a valuable reference for analyzing novel infectious diseases in the future. Moreover, this model is beneficial for the prevention and control of infectious diseases and the formulation of public health safety policies in the future.
