Recent literature suggests that HIV prevalence may be declining in some settings. The objective of this study is to describe seroprevalence among pregnant women accessing Prevention of Mother to Child Transmission (PMTCT) services in programs supported by the Elizabeth Glaser Pediatric AIDS Foundation. Country offices submit site level data on the number of women reached with key PMTCT services to headquarters for review and analysis on a regular basis. Preliminary analysis in nine African countries shows a general downward trend in seroprevalence across a variety of settings. However, these data are representative of a specific sub-population of pregnant women with access to PMTCT services. Rigorous evaluation methodologies are necessary to describe the impact that counseling and testing in the context of PMTCT programs may have in preventing new infections. Moreover, further research is needed to fully describe the population of women accessing PMTCT services over the life of the program.
