Objective: To analyze the blood changes in influenza children in some area within 24-48 hours in the spring of 2022, summarize their change rules, and provide reference diagnosis basis for basic hospitals that cannot conduct pathogen detection and diagnosis of influenza, so as to use medication as soon as possible and avoid delay in the disease. Methods: The analysis of children from December 2021 to April 2022 was mainly within 24-48 hours. The number of statistical cases was 150. Routine blood leukocyte count, neutrophil percentage and lymphocytes within 24-48 hours of onset were counted, and finally integrated and analyzed. Results: 23 children with 2.7~ 4.0 109 (15.3%) / L BC count, 4.0~10.0109 / L: 127 children (84.7%); Neutrophil ratio above 75% in 106 children (70.6%), 68%~75% Children 44 (29.4%), For the former years before age 4 to 6, Including children aged 4 to 6 years, There were 0 children below 68% (0%); Lymphocyte percentage in 0~20% of children in 148 patients (98.7%), Two children (1.3%) of 20%~50% children, More than 50% of the children had 0 cases (0%). The pediatric C-reactive protein level was 52.12 ± 22.54 (mg/L), while the normal pediatric C-reactive protein level was 2.14 ± 1.05 (mg/L). Conclusion: The general trend of statistical cases was normal or decreased leukocyte count, neutrophil percentage significantly increased, lymphocyte percentage significantly decreased, and C reactive protein level significantly increased, which has great reference value for the diagnosis of basic units for influenza.
