Prevention of mother-to-child HIV transmission within the continuum of maternal, newborn, and child health services

Purpose of reviewTo reach virtual elimination of pediatric HIV, programs for the prevention of mother-to-child HIV transmission (PMTCT) must expand coverage and achieve long-term retention of mothers and infants. Although PMTCT have been traditionally aligned with maternal, newborn, and child health (MNCH) services, novel approaches are needed to address the increasing demands of evolving global PMTCT policies.Recent findingsPMTCT-MNCH integration has improved the uptake and timely initiation of antiretroviral therapy (ART) among treatment-eligible pregnant women in public health settings. Postpartum engagement of HIV-infected mothers and HIV-exposed infants has been insufficient, although alignment of visits to the childhood immunization schedule and establishment of integrated mother-infant clinics may increase retention. Evidence also suggests that the integration of maternal HIV testing into childhood immunization clinics can significantly increase the identification of at-risk HIV-exposed infants previously missed by traditional PMTCT models.SummaryTargeted service integration models can improve PMTCT uptake. However, as global PMTCT policy shifts to universal provision of maternal ART during pregnancy (i.e., Option B/B+), these findings must be reexamined in the context of increased service demand and systems burden. Intensive evaluation is needed to ensure quality clinical care is maintained both for PMTCT and for underpinning MNCH services.
