HIV is the most common health concern in Africa. The number of deaths due to HIV is the highest. The main reason why HIV is so prevalent in Africa could be due to the reason it originated there. Another reason why it spreads so extensively is may be because not all of them have access to medical treatment. Even if they manage to diagnose it, they may not be able to afford the extremely expensive medication. Some communities do not believe in having protected sex. They also permit men to have extramarital sex, putting themselves and their spouse in danger.
