Phenotypical profiles of the stimulated monocytes in mild and severe cases. (a) The mean fluorescence intensity (MFI) levels of human leucocyte antigen D‐related (HLA‐DR), CD38, CD69, CD80, CD86, programmed death 1 (PD‐1) and programmed death ligand 1 (PD‐L1) on monocytes of severe and mild enterovirus A71 (EV‐A71)‐infected patients were compared. (b) Comparison of immunophenotypical characteristics of monocytes between severe (n = 20) and mild (n = 20) EV‐A71‐infected patients. The mean values and the standard deviation are indicated. Differences between groups were assessed using the non‐parametric Wilcoxon matched‐pairs test.
