Association between Detection of HIV‐1 DNA Resistance Mutations by a Sensitive Assay at Initiation of Antiretroviral Therapy and Virologic Failure

Antiretroviral therapy (ART) has become more available throughout the developing world during the past 5 years. The World Health Organization recommends nonnucleoside reverse-transcriptase inhibitor-based regimens as initial ART. However, their efficacy may be compromised by resistance mutations selected by single-dose nevirapine (sdNVP) used to prevent mother-to-child transmission of human immunodeficiency virus (HIV)-1. There is no simple and efficient method to detect such mutations at the initiation of ART.
