The subanalysis of phenotypic data in asymptomatic and mild symptomatic recovered individuals displayed comparable immune cell profiles except for higher CD4+ Th cells and lower CD8+ Tc cells at R1, higher CD4+ and CD8+ naïve T cells, and lower CD4+ T effector and CD8+ TEMRA cells at R2 in individuals recovered from mild symptomatic infection. The gene discussed is CD8A; the disease is infection.
