The increasing incidence of Chikungunya virus (CHIKV) as an important public health issue led to the investigation of novel approaches to disease control. In this study, we analyze Chikungunya epidemic model in the presence of Wolbachia-infected mosquitoes, which is a promising biological approach for controlling vector-borne diseases. The basic reproduction number ([Formula: see text]) of the proposed model is calculated using the next generation matrix approach. In this study, we utilize a hybrid methodology that combines the genetic algorithm (GA) and interior point algorithm (IPA) to numerically solve the proposed Chikungunya epidemic model. Our investigation examines the impact of key parameters, such as biting rate, reproduction rate, mortality rate, and transmission probability, on the complex dynamics of disease classes. This analysis provides valuable insights into the transmission dynamics of Chikungunya and highlights the potential effectiveness of interventions based on Wolbachia. We conclude that the numerical findings produced using the hybrid GA and IPA are in good agreement with those obtained using the traditional fourth-order Runge–Kutta (RK4) approach.

Background and Objectives: This study is made to analyze the radiation effect in the flow of magnetohydrodynamic (MHD) Casson nanofluid when subjected to a magnetic field. The velocity slip over inclined nonlinear stretching surface in Forchheimer porous medium is taken into account. The Blood is considered as a base fluid and single-walled carbon nanotubes (SWCNTs) as nanoparticles in this study. The basic purpose of this study is to analyze the heat transfer and MHD effects on the Casson nanofluid which is nowhere found in previous studies and this laydown a pathway for the future researches. Significance: Growing potential of Casson fluid by considering its applications to flow and energy transfer, the current analysis can be of great significance where working fluid used is non-Newtonian in nature. Methodology: The mathematical model consisting of flow and heat equations is solved by using the Runge–Kutta fourth-order method along with shooting method in MATLAB using bvp4c solver. Results: Graphical outputs of velocity and temperature fields are obtained for various values of magnetic parameter M, Prandtl number [Formula: see text], Forchheimer parameter [Formula: see text], permeability parameter [Formula: see text] and concentration parameter [Formula: see text]. The numerical findings of coefficient of local skin friction and local Nusselt number are also tabulated. Casson fluid parameter in an increasing order impacted decreasingly on the skin friction of the fluid while magnetic number upgrade it along the sheet. The stability of fluid flow is effected by volumetric ratio of SWCNT’s nanoparticles. The boundary line temperature increases as radiation parameter rises.
