CD4 T cell distribution post-COVID-19 infection. Comparison of the systemic percentage of (A) CD4 T cells; B Naïve CD4 T cells; C Total memory CD4 T cells; D Central memory CD4 T cells; E Effector memory CD4 T cells (F) EMRA CD4 T cells. PBMCs were isolated from convalescent COVID-19 patients who had mild (n = 15), moderate (n = 29) and severe (n = 55) disease 3–5 months post-infection, and healthy age and sex-matched controls (n = 59). Data represent individual values, mean (centre bar). Statistical analysis by two-sided Mann–Whitney nonparametric test
