Nevirapine resistance was found in 7/16 (43.5%) HIV-1-positive HIVNET 024 infants at 4 to 6 weeks, but no resistance was found at other time points.en-USNevirapine Resistance in Human Immunodeficiency Virus Type 1-Positive Infants Determined Using Dried Blood Spots Stored for Up to Six Years at Room TemperatureJournal Article2016-05-0510.1128/JCM.00254-09
