The study will be conducted among approximately 1,600 women and their infants who received Option B+ PMTCT services at ten facilities in Swaziland. These facilities were included in another study on Option B+ called Safe Generations in which routinely collected patient-level data was abstracted from medical registers. This study has three parts: the first is a review of alternative patient medical records among women and their infants who were documented as LTF in the Safe Generations study. The second component consists of tracing women who are LTF on the phone or in the community to administer a questionnaire. Lastly, an in-depth interview will be conducted among a sub-group of women to explore patterns of care.
