What all do i do to keep from getting aids if i'm traveling through africa?

"All" is the key.: Most people think of unsafe sex as the main way to be exposed to hiv. While that is mostly true, there is another way to get blood-borne illnesses such as HIV in developing countries. The highways there are very dangerous and if you were in an accident with serious injuries you might need surgery and blood transfusion and thus risk HIV or hepatitis. Always wear a seatbelt even in the back seat.
