Title: “Mathematical Models and Analyses of Environmental Temperature on Dengue Fever Transmission”

Abstract: Half the world’s population, about 4 billion people, live in areas with a risk of dengue infection, a mosquito-borne disease, with further increased public health concerns due to the growing spatial spread of the diseases. The environmental temperature plays a major role in the mosquito life cycle as well as the mosquito-human-mosquito dengue transmission cycle. In this talk, I will present mathematical models to study the effects of environmental temperature on mosquito population and dengue transmission. First, we use our periodic dynamical system models to explore how seasonal and diurnal environmental temperature variations affect mosquito survival and dengue persistence. Using newly formulated mosquito reproduction numbers and infection invasion threshold, we performed extensive analyses on the global threshold dynamics to establish the environmental conditions for mosquito survival and dengue persistence. Second, we use the global dynamical analysis of our PDE-based models to determine the role of spatial heterogeneity of environmental temperature on the spread of mosquitoes and dengue. Our results provide novel insights into the theoretical understanding of the impact of climate, which can be beneficial for controlling mosquito vectors and dengue spread.  


The Analysis and Applied Mathematics (AAM) Seminar is intended for Kennesaw State faculty working in the various areas of analysis and applied mathematics to get together to discuss their current work or related questions. Seminars often involve advanced mathematical knowledge. However, the seminars are open to anyone who is interested in attending.


This seminar will be held in-person and virtually.
