CD4 and infection: The primary infection group had a greater viral load than did the serological transition group (P.I. = median: 15.33; IIQ: 6.50–78.50); (S.T. = median: 0; IIQ: 0.0–2.0); p < 0.00001) (Figure 1B) and a lower CD4(+) T lymphocyte count (P.I. = median: 319.50; IIQ: 140.00–443.25); (S.T. = median: 475; IIQ: 245–764); (Past I. = median: 525.50; IIQ: 280.75–938.25); p: 0.0068) (Figure 1C) but a higher CD8(+) T lymphocyte count than did the other groups (P.I. = median: 1024.50; IIQ: 886.25–2136.75); (S.T. = median: 1140; IIQ: 582–1735); (Past I. = median:807; IIQ: 553–1235); p < 0.00001) (Figure 1D).
