Year Quarter
ANC Bookings 2011 Q2 Incorporated PMTCT messaging in VHW training materials, trained and engaged VHWs in community mobilization for PMTCT and conducted mass-media campaigns to promote early ANC bookings.
HIV Testing 2011 Q2 Trained more nurses to offer rapid HIV testing to pregnant women; tracked availability of test kits at site level and helped to redistribute as necessary to avoid stock outs.

CD4 Testing 2011 Q4 Procured 154 POC CD4 testing machines and distributed to MNCH clinics and EDTA tubes for remote clinics to collect and send blood specimens for CD4 testing at sites with CD4 testing machines.
Mothers’ ART 2011 Q4 Introduced ART in MNCH and trained MNCH nurses to initiate eligible HIV-positive pregnant women on ART rather than referring them to existing ART clinics for initiation by doctors.
Infant ARVs 2011 Q2 Changed HIV-exposed infants’ ARV prophylaxis from seven days daily AZT dose to daily NVP dose until 7 days after breastfeeding.
EID 2011 Q2 Incorporated EID training into PMTCT training materials and trained nurses in all MNCH facilities to offer EID services.
