Population-level data reveal widespread HIV drug resistance in sub-Saharan Africa

HIV drug resistance is common across sub-Saharan Africa, with new population-level data showing that more than one in three people on antiretroviral therapy (ART) carried at least one resistance-associated mutation between 2015 and 2019, according to a new analysis published in BMC Public Health. The investigators analyzed HIV drug resistance data from the Population-based HIV Impact Assessment (PHIA) surveys, the first widely available surveillance datasets of their kind in sub-Saharan Africa, to estimate HIV drug resistance prevalence and identify associated factors among adults living with HIV across nine countries between 2015 and 2019.
