CD4 and HIV infectious disease: Being born at home (Crude OR, 3.26 95 % CI 1.24–8.53; p = 0.016), maternal CD4 count during pregnancy less than 100 cells/mm3 (Crude OR, 5.68 95 % CI 1.15–28.05; p = 0.033), absence of any PMTCT interventions for the mother (Crude OR, 6.10 95 % CI 2.45–15.17; p < 0.0001), absence of antenatal care follow up (Crude OR, 5.54 95 % CI 2.27–13.52; p < 0.0001), and mother not enrolled in HIV care and treatment during pregnancy (Crude OR, 4.32 95 % CI 1.66–11.24; p = 0.003) were associated with increased probability of HIV infection at 6–8 weeks.
