2012 — HIV prevention trials require recruitment and retention of populations at higher risk for HIV infection. Epidemiologic studies allow researchers to measure HIV incidence rates while strengthening site clinical research capacity. The studies can also demonstrate whether recruitment, retention and incidence rates are suitable for future prevention trials. Researchers from the Catholic University of Mozambique (UCM), FHI 360 and the Amsterdam Institute for Global Health and Development (AIGHD) collaborated to develop a new clinical research site in Beira, Mozambique, and ascertain HIV incidence.
