Low HIV drug resistance prevalence among recently diagnosed HIV-positive men who have sex with men in a setting of high PrEP use.

Introduction: New South Wales (NSW) has one of the world's highest uptake rates of HIV pre-exposure prophylaxis (PrEP). This uptake has been credited with sharp declines in HIV transmission, particularly among Australian-born gay and bisexual men. Concerns have been raised around the potential for the emergence of tenofovir (TFV) and XTC (lamivudine/emtricitabine) resistance in settings of high PrEP use.
