The 2013 Health budget aimed to strengthen prevention and treatment programmes for TB and HIV and AIDS. An amount of R338 million was allocated to provinces over the medium term to roll out new diagnostic technology for TB (GeneXpert), while R484 million was allocated to offset a decrease in the United States donor funding for Aids programmes. The National Institute of Communicable Diseases received R78 million to strengthen surveillance of rotavirus, pneumococcus, HIV, tuberculosis and other infectious diseases, with R800 million set aside to expand antiretroviral treatment to cover 500,000 more people per year.
