The epidemiology of AIDS involves studying the patterns, causes, and effects of health and disease conditions in defined populations. Globally, the burden of AIDS is disproportionately higher in certain regions, particularly in Sub-Saharan Africa. Factors such as socio-economic status, access to healthcare, and cultural practices play significant roles in the distribution and prevalence of the disease. According to the World Health Organization (WHO), as of 2020, approximately 37.7 million people were living with HIV worldwide. Despite significant progress in reducing new infections and AIDS-related deaths through antiretroviral therapy (ART), challenges remain in achieving universal access to treatment and prevention services.
