Assessing the prevalence of HIV among Afghan immigrants in Iran through rapid HIV testing in the field

Throughout the world, many migrant and mobile populations are at elevated risk for HIV. Iran has a large immigrant population from neighboring Afghanistan; however, few data exist on the prevalence of HIV in this community. In 2008, we conducted a study to assess the presence of HIV infection among 477 immigrants in a town to the northeast of Tehran using a rapid test in the field. HIV prevalence was 0.2% (95% CI 0.005-1.2) with one person HIV-positive. We recommend periodic HIV sero-surveillance with detailed behavioral measures for this population in the future.
