Patterns of HIV Care Clinic Attendance and Adherence to Antiretroviral Therapy Among Pregnant and Breastfeeding Women Living With HIV in the Context of Option B+ in Zimbabwe.

Background: Consistent use of antiretroviral therapy (ART) during pregnancy and breastfeeding reduces the likelihood of mother-to-child HIV transmission. All pregnant and breastfeeding women living with HIV in Zimbabwe are offered ART with same-day initiation regardless of CD4 count (Option B+). We investigated patterns of clinic attendance and adherence to ART among HIV-infected pregnant women in Zimbabwe.
