Figure 1.

Viral load kinetics for the 4 children with sustained virologic suppression. All 4 children had positive human immunodeficiency virus (HIV) polymerase chain reaction (PCR) within 48 hours of birth and a minimum of 2 subsequent detectable viral load assay results. Only case 1 had a viral load test performed on day 1 of life; the other 3 had viral load testing performed only after receiving the birth HIV PCR result. A biphasic viral load decline is clearly evident in case 1. In the other 3 cases, results are consistent with the second-phase decline of viral load. Abbreviations: cART, combination antiretroviral therapy; HIV, human immunodeficiency virus; PCR, polymerase chain reaction.
