HIV-infected mothers and exposed infants followed up for six weeks post-delivery within the national PMTCT program.

<p><b>Mothers ‘linked' to HIV/AIDS care</b> were HIV-positive mothers recorded in the antenatal register, that appeared in the facility pre-ART register and had a clinic number with at least one clinical visit recorded by a clinician six weeks post-delivery. <b>Babies ‘linked' to Early Infant Diagnosis (EID)</b> were babies born to HIV-infected mothers (as per antenatal and labor registers), that were registered in the facility EID register with at least one clinical visit recorded by a clinician by six weeks post-delivery. <b>Mother-baby pairs ‘linked'</b> were mother-baby pairs identified from the antenatal and labor ward registers, that had the HIV-infected mother registered in the HIV clinic and the baby registered in the EID program by 6 weeks post-delivery. Babies ‘not eligible' were unborn and/or below 6 weeks of age at the time of the study were excluded.
