The Bending the Curves catalytic project, sought to demonstrate the feasibility and acceptability of ambitious strategies for testing, treatment and prevention of HIV and TB in Eshowe and Mbongolwane, in KwaZulu-Natal (KZN), representing semi-urban and rural settings, respectively. It concentrated on prevention, HIV counselling and testing (HCT), linkage to care, and retention in care and adherence, which resulted in exceeding the UNAIDS 90-90-90 targets two years ahead of the deadline. This evaluation had the objective to assess the effectiveness and replicability of MSF intervention and to identify those elements within the project which have played a key role. Its intended use is aimed to primarily inform MSF-OCB in their conversations with South Africa's DoH on the national HIV program. It may also be used by MSF in their conversations with other regional and international actors.
