The HIV epidemic in South AfricaThe HIV epidemic in South Africa
HIV prevalence in pregnant women attending public antenatal clinics in South Africa 1989-2006
Africa needs newAfrica needs newHIV prevention technologiesHIV prevention technologies
In South Africa the epidemic continues to grow despite increased prevention efforts Male condom distributed in 2002/3: 358 million Female condom distribution doubled from 1,3 million in
2003 to 2,6 million in 2004
Combating the HIV epidemic is not only about scaling proven prevention – we also need new prevention technologies
New HIV prevention technologies are urgently needed in Africa, especially those that empower women

Women in Africa actively participate in microbicide research…
… microbicides offer the Women of Africa a prevention method that they can use and
control to reduce their risk of HIV infection

ConclusionConclusion Need a women-controlled HIV prevention method if
we are to alter the course of the HIV epidemic in Africa
Women of Africa want to actively participate in microbicide trials
First antiretroviral microbicide effectiveness trial is underway as a joint project funded by both the United States and South African governments
Two large effectiveness trials planned by MTN and IPM
We can achieve the goal of a safe & effective microbicide through working together in partnership
