UNAIDS Estimates 5-15 Men Will Need to be Circumcized to Prevent One New Infection

It costs about $30 USD to circumcise one man in sub-Saharan Africa where HIV rates are highest. Using a new mathematical modeling system developed in collaboration with UNAIDS, WHO and the South African Center for Epidemiological Analyses, it is estimated that between 5-15 men, at a cost of approximately $150-900 USD, need to be circumcised in order to prevent just one new HIV infection.

In an article published by AIDSmap News, it is also mentioned that even if newly circumcised men reduce their use of condoms, circumcision can still reduce the risk of HIV transmission from HIV positive men to HIV negative women. Albeit, if men resume sexual activity too soon after the procedure, their HIV negative partners would be placed at higher risk of transmission. Data shows that to circumsise  HIV positive men would lead to no significant decrease of new infections, so primary motivation for cicumsision campaigns should focus on uncircumcised HIV negative men who are risk for infection.

Statistics concerning male homosexual activity is currently unavailable. However, the computer model used is based on Southern African populations, in which heterosexual sexual activity is the primary cause of infection.
