A secondary analysis of retention across the PMTCT cascade in selected countries: Rwanda Malawi Kenya and Swaziland.

This study constructed cohorts of HIV-positive pregnant women and their infants by reviewing facility PMTCT labor and delivery post natal care and laboratory registers/records from the time of the mother’s initial registration. We then tracked their retention in the program over 10-12 months. Four countries were selected as examples of countries implementing different models of PMTCT: Rwanda (Option B) Malawi (Option B+) Kenya (Option A) and Swaziland (Option A).
