CONTENTS
• Rationale for birth testing in South Africa
• Anticipated implementation challenges
• One year Results (June 2015 – May 2016)
oBirth testing coverage
o In utero transmission rate
• Next Steps2
Rationale for Birth Testing
• Testing at 6 weeks too late to prevent morbidity, mortality and loss to follow up in ±20% of perinatallyinfected infants
• High PMTCT coverage:
– in utero > intrapartum transmission (IU:IP = ± 3:1)
• Captive population of HIV-exposed neonates
– >90% deliveries in maternity unit
– maternal HIV testing at delivery
– identifies virtually all HIV-exposed neonates for testing

Anticipated Challenges
• Reverse gains of 6-week EID program
• 2nd HIV PCR required to detect IP infections (10 weeks)
• Training - HIV PCR into new location & staff
• Testing & result receipt in 2 different facilities: new models for linkage to care

HIV-infected neonates in S.A.Jun 2015 – May 2016
Graphics: N.Ndlovu, Health Systems Trust
• Link every HIV+ neonate to care & assess outcomes
• Training & mentorship– Improve rates of later testing (10 wks-18 mo)
– Neonatal treatment is complex
• Longitudinal surveillance to– enumerate HIV-infected e.g. unique identifiers and
patient linking algorithms
– monitor guideline implementation e.g. confirmatory testing
– Monitor linkage to and outcomes of care
• Evaluate EID POC testing at birth
