Pre-stress = blood test data of medical workers before providing medical service for Wuhan COVID-19 patients; Post-stress = blood test data of medical workers after providing medical service for Wuhan COVID-19 patients; M = male; F = female; WBC = white blood cell; NEUT = neutrophil; LYM = lymphocyte; MONO = monocyte; EOS = eosinophil; BASO = basophilic granulocyte; NEUT = neutrophil; NLR = neutrophil-to-lymphocyte ratio; MLR = monocyte-to-lymphocyte ratio.

Continuous variables were analyzed using one-way ANOVA test. *p < 0.05, **p < 0.01 vs controls; #p < 0.05, ##p < 0.01 vs pre-press. The symbols ↑ and ↓ represented significantly higher or lower.
