The map above shows the HIV prevalence in the world. No surprise to many, it is overwhelmingly prevalent in Africa. Covering mostly central and southeastern Africa, HIV has become an epidemic within the past few decades due to unsafe sex, infected needles, and viral transmission through pregnancies. Although this map does not show HIV in children, the infection in this half of the world is mind blowing. The majority of Africa has a poor economy. This in turn makes it difficult for most Africans to afford education for people, health care, and vaccines.
