title: Higher viral load may explain the dominance of CRF02_AG in the molecular epidemiology of HIV in Ghana.
abstract: Phylogenetic analysis of Ghanaian plasma samples from 84 asymptomatic candidate blood donors and 150 AIDS patients revealed a 63% prevalence of HIV-1 CRF02_AG. HIV-1 viral load in both populations was quantified using real-time reverse transcriptase-polymerase chain reaction. In asymptomatic candidate blood donors infected with CRF02_AG, the viral load was significantly higher than in donors infected with other HIV-1 molecular forms. A higher viral load of CRF02-AG is compatible with higher infectivity and prevalence.
