Abstract:Dengue fever remains a significant public health concern in many tropical and subtropical regions worldwide. In this seminar, Prof. Guiro presented a mathematical modeling framework for studying the transmission dynamics of dengue fever, with application to the Burkina Faso context. The work began with a general multi-strain dengue model designed to capture the circulation and interaction of multiple viral strains. For the Burkina Faso case study, a reduced two-strain version of the model was considered to investigate disease transmission and reinfection dynamics.The model accounts for the possibility that individuals infected with one strain may subsequently become infected with another strain. It also distinguishes between symptomatic and asymptomatic infections, while incorporating hospitalization of symptomatic individuals and other key epidemiological processes. Mathematical analysis was performed to establish the disease-free and endemic equilibria of the model and to characterize conditions for disease persistence and control. Numerical simulations were presented to illustrate the transmission dynamics of dengue fever and the impact of key epidemiological parameters on disease spread. The study demonstrates the value of mathematical modeling in understanding the complex dynamics of multi-strain infectious diseases and supporting evidence-based public health decision-making.
