According to UNAIDS data, there are approximately 7.1 million people living with HIV in South Africa, making it the biggest HIV epidemic in the world. More than three million people are receiving antiretroviral treatment and the epidemic disproportionately affects key populations such as sex workers and men who sex with men (MSM).

NACOSA is a network of civil society organisations (CSOs) working together to turn the tide on HIV, AIDS and TB in Southern Africa. NACOSA provides accredited training, mentoring and technical assistance, and resources to support service delivery on the ground, particularly among key populations and women and girls.

Born out of a national conference in 1991, NACOSA played a central role in mobilising an effective, multi-sectoral response to HIV, AIDS and TB in South Africa. Learning from their 13 years of formal operation, they believe that when people come together to tackle community challenges, they have a stronger voice and are more effective at finding solutions.

In 2017, NACOSA reached more than 240,000 people with HIV prevention activities and provided more than 174,000 people with integrated HIV and sexual and reproductive health (SRHR) services. NACOSA also contributed to over 10% of the national coverage of HIV prevention programmes for sex workers by reaching over 56,000 sex workers with prevention and 7,000 with treatment, care and support. NACOSA has also been very vocal in pushing for sex work decriminalisation in South Africa and for the strengthening of public awareness and political will around preventing gender-based violence (GBV).
