Characterization of nevirapine (NVP) resistance mutations and HIV type 1 subtype in women from Abidjan (Côte d'Ivoire) after NVP single-dose prophylaxis of HIV type 1 mother-to-child transmission.

Nevirapine (NVP) single dose is widely used in developing countries to prevent HIV-1 mother-to-child transmission. However, this regimen selects key drug resistance mutations that can impair further HAART efficacy. We studied the HIV-1 reverse transcriptase genotype from 29 Ivoirian women 1 month after an NVP single-dose prophylaxis.
