In sub-Saharan Africa, there is a high rate of unintended pregnancy, particularly among HIV-positive women, and the majority of HIV infections are sexually transmitted or transmitted as a result of pregnancy, childbirth, and breastfeeding. Yet many health facilities do not provide integrated HIV and SRH services. Integration has the potential to increase access and uptake of health services, increase job satisfaction among providers, more effectively distribute facility workloads, and reduce facility costs. The Integra Initiative represents an effort to respond to the need for high-quality evidence on the feasibility, effectiveness, cost, and impact of different models for delivering integrated HIV and SRH services in settings with high and medium HIV prevalence in sub-Saharan Africa. The “Steps to Integration” series provides a guide on how to integrate HIV and SRH services based on findings from the Integra Initiative, managed by the International Planned Parenthood Federation in partnership with the London School of Hygiene & Tropical Medicine and the Population Council. Issue 1 of the series explores the integration of sexual and reproductive health and HIV services
