14.5 of the worlds population lives in Africa. But 69% of the people that have HIV in the world are in Africa. Also, 72% of deaths in 2009 were caused by aids in Africa. In 2005 22.5 million people in Sub-Saharan Africa were diagnosed with HIV and 1.3 million of those people died of aids. A theory of how HIV/AIDS started was spread from monkeys, chimpanzees, and apes. This disease was spread to the human kind because of blood tests on monkeys and the studying of monkeys. Sadly, about every 13 seconds, a person in Africa dies of the deadly disease of aids.
