The evaluation of complete blood count ratios in children with 2019 novel coronavirus (2019‐ncov) infection

We investigated hematological parameters included WBC, neutrophil, lymphocyte, monocyte, eosinophil, basophil and platelet count. Moreover, we evaluated hematological ratios such as NLR, MLR, ELR, BLR, PLR and MPV/PC. Two groups were classified as positive RT-PCR with bilateral patchy shadows or ground‐glass opacity in their lungs and negative RT-PCR for 2019‐nCoV. A total of 204 children were enrolled 2019-nCoV positive and negative. Seven 2019-nCoV positive patients were asymptomatic. Fever was mostly seen symptom in 2019-nCoV positive and negative patients at admission. White blood cell, neutrophil, monocyte, eosinophil, basophil and platelet count were significantly lower in 2019-nCoV positive patients than that of negative patients (p<0.05). While NLR, MLR, PLR and MPV/PC had no statistically difference, ELR and BLR ratios showed distinct significance between two groups (p<0.05). Hematologic indices haven’t been analyzed before in children with 2019-nCoV. WBC, ELR and BLR might be valuable ratios for the situation of inflammation in coronavirus infection.
