Perinatal Exposure Surveillance

The Georgia Department of Public Health (GA DPH) conducts surveillance of perinatal HIV exposure, which is defined as any infant whose mother has tested positive for HIV regardless of the infant’s HIV status. Perinatal HIV exposure surveillance has been conducted in Georgia since 2016. Approximately 200–250 women with HIV giving birth are identified each year.

  • It is mandatory for healthcare providers and laboratories to report perinatal HIV exposure (see the Disease Reporting Page and Georgia Code O.C.G.A. § 31-12-2). For infants whose mother has tested positive for HIV, all infant labs from birth to 18 months must be reported and a Pediatric Case Report Form completed within seven (7) days. See the Case Reporting Page for details on reporting for both healthcare providers and laboratories. 

Vertical Transmission Surveillance: As part of perinatal HIV exposure surveillance, GA DPH monitors the occurrence of vertical HIV transmission, which is the transmission of HIV from mother to infant during pregnancy, labor and delivery, or postpartum through breastfeeding. 

Without any intervention, the risk of HIV transmission from mother to infant ranges from 15-45% (see Reference #1 below). However, the risk of transmission can be reduced to less than 1% when appropriate preventative action is taken (see Reference #2 below). Successful prevention of vertical transmission of HIV requires interventions that span the pregnancy, labor and delivery, and postpartum periods. This coordinated effort is critical to ensure that no infant is perinatally infected with HIV.

Assessing Adherence to Guidelines and Opportunities for Outreach: As part of perinatal HIV exposure surveillance, GA DPH aims 1) to understand if the guidelines for prevention of perinatal transmission are implemented and 2) to identify opportunities for outreach to improve health outcomes for the mother and baby during pregnancy, labor and delivery, postpartum, and beyond.

Vertical Transmission Trends in GA: The figure below shows overall improvements in the prevention of vertical transmission of HIV in recent years, likely due to increased efforts in improving patient follow-up and provider adherence to proper guidelines in caring for women during pregnancy, labor and delivery, and the postpartum period.

The average number of perinatal HIV transmissions dropped from an average over 5 perinatal HIV transmission per year between 2009-2016 to below an average of 3 transmissions between 2017-2023.

Average perinatal transmissions were lower in 2017-2023 compared to 2009-2016

Perinatal HIV Clinical Guidelines

Recommendations for the use of antiretroviral drugs during pregnancy and interventions to reduce perinatal HIV transmission are available at Clinical Info | HIV.gov

The Perinatal HIV Hotline is a federally funded service that provides clinicians with advice on indications and interpretations of HIV testing in pregnancy, and consultation on antiretroviral use during pregnancy, labor and delivery, and the postpartum period. It is available at 1-888-448-8765, 24 hours a day, 7 days a week.

History of Enhanced Perinatal Surveillance (EPS)

Perinatal HIV exposure surveillance was previously conducted in Georgia through CDC's Enhanced Perinatal Surveillance project from 2005–2010. It was an extension of routine HIV and AIDS surveillance activities to evaluate prevention of perinatal HIV transmission, and screening and treatment interventions for infants born across all of Georgia (population-based), then later for infants born at seven Regional Perinatal Centers throughout Georgia (facility-based). Georgia resumed EPS in 2016, using lessons learned to improve upon the initial EPS work, and returning to the population-based surveillance method in Georgia.
