Peripheral NK cell kinetics post-infection. Frequencies of (A) total NK cells (CD56+), (B) immature NK cells (CD56brightCD16-), (C) mature CD16+ NK cells (CD56dimCD16+), and (D) mature CD16- NK cells (CD56dimCD16-) were calculated for samples obtained from individuals at baseline and at timepoints after initial PCR+ test for SARS-CoV-2. All available samples were analyzed. Number of samples at baseline n = 87, post-PCR samples analyzed at days 0–6 (n = 27), 7–13 (n = 86), 14–20 (n = 14), 21–27 (n = 12), 28–34 (n = 24), 35–41 (n = 47), 42–48 (n = 6), 49–55 (n = 35). Analyses between timepoints were conducted using Dunnett's multiple comparisons test (**p < 0.01, ***p < 0.001, ****p < 0.0001).
