^aHAART, highly active antiretroviral therapy; IQR, interquartile range; ND, not determined.

^bData are for 72 mothers at the time close to the time of the infant's birth and 74 mothers during the infant's recruitment.

^cData are for 53 mothers at the time close to the time of the infant's birth and 75 mothers during the infant's recruitment.

^dViral load data were available for 78 of the mothers. Data in parentheses represent the number of mothers with the indicated viral load/total number of mothers tested.

^eMothers for whom data on the duration on HAART close to the time of the infant's birth were missing.
