Significantly higher saliva viral load was observed in children with total lymphopenia (mean log10 viral load 5.8 vs. 4.9 copies/mL, p = 0.031), CD3 lymphopenia (mean log10 viral load 6.1 vs. 5.1 copies/mL, p = 0.031), and CD4 lymphopenia (mean log10 viral load 6.4 vs. 5.1 copies/mL, p = 0.013) compared to those without lymphopenia (Table 2). Here, CD4 is linked to lymphopenia.
