Why are the highest rates of HIV infection in the countries of sub-Saharan Africa? These countries have unusually high populations of gay men. People in this region often do not have access to HIV medications, sterilized needles, or condoms. HIV originated in this region and has infected human populations here the longest. Effective programs to educate and raise awareness about prevention face serious funding problems.

Explanation:

The sub-Saharan countries of Africa have the highest rates of HIV infections mainly due to lack of resources. There are not enough effective programs to educate and raise awareness about prevention because there are serious funding problems. This lack of funding also prevents the region from obtaining the necessary HIV medications, sterilized needles, or condoms that are needed in order to slow down and begin preventing the disease from continuing to spread.
