South African health statistics and the potential effects of multidisease screening

(A) HIV estimates are obtained from the Thembisa model estimates for 2016, whereas diabetes and hypertension estimates are from the 2012 South African National Health and Nutrition Examination Survey. Controlled on treatment is defined in the case of HIV as having a viral load less than 400 copies per mL, and in the case of diabetes as a HbA_1c concentration less than 7%. Estimates of treatment coverage and control rates among hypertension cases are obtained from a national survey in 2010. (B) The expected fraction of screened individuals testing positive, the expected fraction of newly diagnosed individuals, and the expected fraction of individuals linking to treatment services in the context of a multidisease screening programme implemented between 2018 and 2028.
