The prevention of mother-to-child transmission of HIV-2 is less certain than for HIV-1, from which most of the recommendations have been derived. Transmission of HIV-2 is less frequent (perhaps 10-fold less efficient), but HIV-2 is intrinsically resistant to the non-nucleoside RTI nevirapine, removing one option for pharmacologic prophylaxis at the time of delivery.
