The prevalence of drug-resistant HIV strains in Uganda has risen from 8.6 per cent to 12 per cent in the last five years, one of the highest rates in Sub-Saharan Africa, according to a recent study. The PharmAccess African Studies to Evaluate Resistance (PASER) monitoring cohort study report for 2008-2012 found that the prevalence of transmitted drug resistance among people who have never taken life-prolonging antiretroviral (ARV) medication was substantially higher in Uganda.
