From: A novel acute HIV infection staging system based on 4thgeneration immunoassay
Frequency of cell subsets in the peripheral blood at time of acute HIV infection using Fiebig and 4thgeneration enzyme immunoassay staging systems for CD4+ T cells (A), CD8+ T cells (B), CD19+ B cells (C) and CD16+56+ natural killer cells (D). FI to IV are Fiebig acute HIV infection stages I to IV. 4thG 1 to 3 are 4thG acute HIV infection stages 1 to 3. The whiskers indicate median (inter-quartile range).
