Transmitted, or any pretreatment drug resistance (TDR, PDR) can compromise efficacy of first-line antiretroviral therapy (ART). In Peru, genotypic resistance testing is not routinely performed before ART initiation, and estimated PDR prevalence prior to 2012 ranged from 1.0% to 4.7%. We aimed to update estimates of PDR prevalence in men who have sex with men (cis-MSM) and transgender women (TW).
