CD4 and HIV infectious disease: Median pre-treatment HIV RNA load was numerically lower in participants who initiated ART during acute HIV infection compared with chronic HIV infection (median (IQR) 4.4 (3.2, 5.7) vs 5.3 (4.8, 5.4) log10 HIV RNA copies/mL, p = 0.61) and current CD4+ T-cell count was similar between the two HIV-positive groups (Table 1).
