MTCT – mother–to–child transmission, CI – confidence interval
*Conducted during months 17 (August 2011) to 24 (March 2012) after PMTCT Option A became policy.
†Conducted during months 31–38 after PMTCT Option A was adopted and includes the first 2 months (April and May 2013) of PMTCT Option B policy implementation.
‡Sample realization <70%, thus these MTCT estimates may be subject to bias.
