- At entry, infant is at increased risk of HIV acquisition.
- Cohorts 1 and 2, Strata FF only:
- Birthing parent had acute HIV during this pregnancy; or
- Birthing parent with detectable viral replication (plasma HIV RNA results at least 50 copies/mL) during pregnancy who did not have confirmed viral suppression, defined as at least two consecutive plasma HIV RNA results less than 50 copies/mL from specimens obtained at least four weeks apart with the latest result within four weeks prior to delivery; or
- Birthing parent not receiving appropriate ART for at least two weeks, with any part of the two-week period occurring within four weeks prior to delivery, based on birthing parent's report or available medical records.
