^aBM = breast milk transmitter, IUT = in utero transmitter

^bTimes refer to sampling time (months post-delivery) at which samples were collected

^cCD4+ cell counts were measured at delivery for each patient

^dViralload data from available samples used in this study; BML = left breast milk; BMR = right breast milk

^eNA = viral load was unavailable although sequences were generated and analyzed in this study
