As the world marks World Aids Day today, this week the Human Sciences Research Council released a report revealing that although KwaZulu-Natal, the Eastern Cape, Mpumalanga, and the Free State have the highest number of people infected with HIV, they've managed to increase viral suppression by nothing less than 80%. Meanwhile, Doctors without Borders says it will close its long-term HIV and TB projects in Eshowe and Mbongolwane in Kwazulu Natal, ending the organization's more than 20 years of continuous HIV/TB operations in South Africa.Sakina Kamwendo spoke to Sean Christie, Advocacy Manager at Doctors Without Borders
