Hemogram indicators in children aged 7–14 years with new coronavirus infection

Abstract

The research is focused on the evaluation of a general blood test in children with a new coronavirus infection, depending on the severity of the disease. 107 patients with virus-identified new coronavirus infection aged 7–14 years were examined. 19 (17.8%) were diagnosed with asymptomatic, 69 (64.4%) mild, and 19 (17.8%) moderate COVID-19. The control group is represented by 75 healthy children. The hemogram indicators in each group were analyzed, a correlation analysis of the red and white blood cell counts with the severity of the disease was carried out. In children with a new coronavirus infection, a significant decrease in the blood hemoglobin relative to the control group was revealed, although not exceeding the normal values. An inverse correlation was established between a decrease in the WBC and absolute lymphocytes count and the severity of clinical manifestations of the disease.
