We combined HIV tests with existing medical check programs to increase the uptake. In the foregoing survey we undertook previously, it was suggested that fears and stigma of HIV/AIDS were the primary reasons given by the employees for not taking the test. To counter these, we implemented randomized interventions. We find substantial heterogeneity in responses by ethnicity. Africans and Colored rejected the tests most often. Supportive information increased the uptake by 6 to 16% points. A tradeoff in targeting resulting in stigmatizing the targeted and a reduction of exclusion error is discussed.}, title = {Impacts of an HIV counseling and testing initiative -- results from an experimental intervention in a large firm in South Africa}, year = {2016} }
