摘要：The talk will start with some introduction to vector-borne pathogen transmission modeling. The focus will be on recent progress on modeling and analyzing how co-occurrence, in the spatiotemporal proximity of a host, of a susceptible vector with some infected vectors enables the pathogen transmission through a non-systemic transmission route (in collaboration with Xiaotian Wu and Xue Zhang). The talk will then try to compare this transmission route with a potential respiratory disease transmission pathway through contaminated packages of frozen foods. The audience will be invited to an interactive co-development of a potential transmission model to assess the risk of droplet-contaminated food package spread of viral diseases.

摘要：A recent experimental study suggests that the engineered symbiotic bacteria Serratia AS1 may provide a novel, effective and sustainable biocontrol of malaria. These recombinant bacteria have been shown to be able to rapidly disseminate throughout mosquito populations and to efficiently inhibit development of malaria parasites in mosquitoes in controlled laboratory experiments. In this talk, I will report a recent work in which we develop a climate-based malaria model which involves both vertical and horizontal transmissions of the engineered Serratia AS1 bacteria in mosquito population. We show that the dynamics of the model system is totally determined by the vector reproduction ratio Rv, and the basic reproduction ratio R0. If Rv<1, then the mosquito-free state is globally attractive. If Rv>1 and R0< 1, then the disease-free periodic solution is globally attractive. If Rv>1 and R0>1, then the positive periodic solution is globally attractive. Numerically, we verify the obtained analytic result and evaluate the effects of releasing the engineered Serratia AS1 bacteria in field by conducting a case study for Douala, Cameroon. We find that ideally, by using Serratia AS1 alone, it takes at least 25 years to eliminate malaria from Douala. This implies that continued long term investment is needed in the fight against malaria and confirms the necessity of integrating multiple control measures.
