Slide 1-

TESTING AT BIRTH – UPDATE FROM SOUTH AFRICA Gayle Sherman Centre For HIV and STI, National Institute for Communicable Diseases Department of Paediatrics and Child Health, University of the Witwatersrand 8th International Workshop on HIV Pediatrics 15 July 2016
Slide 2-

CONTENTS Rationale for birth testing in South Africa Anticipated implementation challenges One year Results (June 2015 – May 2016) Birth testing coverage In utero transmission rate Next Steps 2
Slide 3-

Rationale for Birth Testing Testing at 6 weeks too late to prevent morbidity, mortality and loss to follow up in ±20% of perinatally infected 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 3
Slide 4-

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 4

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 11 NEXT STEPS
