It is an exciting time for the Option B+ team, as our cohort data collection is now underway! Our first participants were enrolled at the end of July, 2016 and completed their baseline surveys. Patients in the cohort are HIV-infected and are either initiating or continuing antiretroviral therapy (ART) during pregnancy. Baseline surveys are conducted in the second or third trimester of pregnancy, with follow-up surveys at 3, 6, and 12 months postpartum to measure potential individual, social, and contextual factors affecting engagement in HIV care. A subset of the women will complete in-depth interviews to help us gain a richer understanding of women’s lives and facilitators and barriers to care engagement. We are grateful to the participants who are enrolling in the cohort and look forward to working with them and our dedicated team throughout the duration of the study.
