Mathematical Model of Malaria Transmission Dynamics: Evaluating the impact of Asymptomatic and Resistant Strains in Human Hosts
The paper presents a mathematical model of malaria transmission dynamics that incorporates the asymptomatic stage and resistant strains in infectious humans. We identified the disease-free (free malaria) and endemic (persistence of malaria) equilibriums of the model. Using the basic reproduction number R0, we constructed a suitable Lyapunov function to demonstrate the global asymptotic stability (GAS) of the disease-free equilibrium point. When R0 ≤ 1, the disease-free equilibrium is global asymptotically stable. For R0 > 1 we analyzed the global asymptotic stability (GAS) of the endemic equilibrium. We conducted the local sensitivity analysis and numerical simulations for different scenarios. Our findings highlight the significant role of asymptomatic humans and resistant strains in the transmission dynamics of malaria. Therefore, the well-known strategies against malaria should be revised.
