Crimean-Congo hemorrhagic fever (CCHF) is an infectious disease transmitted by ticks that has a high fatality rate in Africa, Asia, and Eastern Europe. The CCHF virus is believed to be spread by the hard tick genus Hyalomma. In addition, ticks and animals contribute to the virus's natural transmission cycle, allowing it to persist in the wild. This virus is transmitted through the bite of an infected tick or through contact with the blood or other bodily fluids of an infected animal. In this study, a compartmental model is utilised to develop a dynamical system of non-linear ordinary differential equations that accounts for all possible situations of virus transmission. This viral hemorrhagic outbreak's rate of spread can be approximated using the basic reproduction number. Adjusting the global stability of the model facilitates multi-group pandemic study. To visually observe the model's dynamics, numerical simulation is utilised.
