MedicalResearch.com Interview with: Dr. Richard J. Hayes, DSc, FMedSci Professor of Epidemiology and International Health London School of Hygiene and Tropical Medicine MedicalResearch.com: What is the background for this study? Response: HIV incidence rates remain at very high levels in many parts of southern Africa. Universal testing and treatment (i.e., ensuring that everyone in a community tests for HIV and that everyone diagnosed with HIV is started on treatment as soon as possible) has been proposed as a strategy to achieve steep reductions in HIV incidence in generalized epidemics. Prior trials have shown inconsistent results as to whether this strategy could be effective. HPTN 071 (PopART) was carried out in 21 urban communities in Zambia and South Africa, with individual communities randomly assigned into one of three arms: A, B or C. The 14 communities in Arms A and B received annual rounds of home-based HIV testing by community health workers who supported linkage to care, antiretroviral therapy (ART) adherence and other HIV services. The seven communities in Arm C received the local standard of care. We looked to see if the HIV incidence in the communities receiving universal testing and treatment would be lower (over time) compared to the incidence in the standard of care communities. (more…)
