#7. AIDS and other diseases
Africans are generally united in the view that AIDS and other infectious diseases are the top threat to the globe. Africa has the highest rates of HIV/AIDS prevalence in the world and the recent Ebola outbreak has spread in the continent’s west. Ugandans are the most worried about AIDS (44%), followed by Tanzanians (41%), South Africans (35%), Kenyans (29%) and Senegalese (29%). In Nigeria, where Boko Haram terrorists in the restive north of the country are creating havoc, 38% say religious and ethnic hatred is the biggest problem for the world.
