HIV/AIDS has had significant geographic impacts across local, national, and international scales in South Africa. At the local level, the disease has disproportionately affected the poor and black populations due to factors like poverty, lack of education, and sexual violence. Nationally, South Africa has seen its life expectancy drop dramatically and around 10% of its population is HIV positive, putting strain on healthcare resources. Internationally, HIV/AIDS has reduced life expectancy in many African countries and is now the fourth leading cause of death globally, with an estimated 36 million people infected worldwide mostly in developing areas.
