Analyzing the Dynamics of HIV/AIDS Phobia with Stability and Awareness Strategies

Abstract

One of the risks to global health is sexually transmitted diseases (STDs). Usually, diseases do not cause death, but 50% of deaths are caused by fear of disease. This causes policymakers and experts studying diseases to become increasingly concerned. In this section we discuss about HIV/AIDS phobia, a particular type of nosophobia is an excessive and illogical dread of contracting HIV/AIDS. It is still a major global health concern due to its high death rate, and in most African nations as well as other places, it is the main source of HIV/AIDS anxiety. We develop a five-component deterministic model to examine how phobia affects HIV/AIDS dynamics within a particular population. The system's HIV/AIDS-free equilibrium is considered asymptotically stable when the effective reproduction number R_0< 1, and unstable in other cases. Additionally, we used to investigate the endemic equilibrium's stability by using the Lyapunov function, positivity, boundedness, Lipschitz condition, and the conditions for the existence of uniqueness are discussed. The outcome demonstrates that everyone must have awareness about HIV/AIDS. Unfortunately, those affected with HIV/AIDS don’t fear; take healthy food, and medicines; and exercise regularly; the counselling about HIV/AIDS will prolong life and reduce the phobia of HIV/AIDS in the population. The HIV/AIDS phobia epidemic model is analyzed by way of Matrix Laboratory.
