Reducing HIV Levels Across the World by Ken Brower. Various campaigns are created to stop the spread of HIV infections that run rampant, especially in countries like Africa. It is disappointing when an initiative fails to yield the expected results, as was the case with a study that spanned three years in several Zimbabwe communities. Researchers were hoping a program which offered free condoms, peer-to-peer education for the entire community and counseling sessions along with treatment of STD's aimed at women in the sex industry and their male counterparts would have an impact on HIV infection rates amongst the sex industry as well as the whole community. However, the study determined that this initiative to impact those people who had much higher risk of being infected with HIV (sex workers and clients) did very little in reducing the rates of HIV infection in the general population. While this initiative actually succeeded in lowering the number of infections of HIV in men, it did not reduce that risk for women.
