  • a ID, identification.

  • b WT/WT, homozygous WT CCR5 genotype; WT/Δ32, heterozygous CCR5 genotype.

  • c Dried blood spots were analyzed within 48 h of inoculation of blood collection cards (time zero) or 3, 6, or 12 months after inoculation of blood collection cards.

  • d WT, WT CCR5 allele probe; Mut, Mut CCR5 allele probe.
