Abstract: OBJECTIVE To analyze the status and risk factors for influenza A virus pneumonia in children. METHODS A total of 186 children infected with influenza A virus in the Henan Children's Hospital from Jun 2020 to Jun 2022 were retrospectively collected as the research subject. According to whether the patients developed pneumonia, they were divided into the pneumonia group (n=42) and the noon-pneumonia group (n=144). Nasopharyngeal secretions and pulmonary sputum were collected for pathogen detection when the child patients were admitted to hospital. Clinical data of the two groups were collected to analyze the morbidity status of the children with influenza A viral pneumonia, and its risk factors were analyzed by univariate and multivariate logistic regression methods. RESULTS The incidence of influenza A viral pneumonia in children was 22.58%, and the top three age groups were >12 and ≤36 months (42.86%), >6 and ≤12 months (26.19%), and >36 and ≤60 months (19.05%). The severity of the disease was mainly mild,with the clinical main symptoms of respiratory symptoms and lung rales, chest imaging lesions of both lungs, and the combination of bacterial infection. Male, time from onset to the first visit >48 h, time from onset to antiviral treatment >48 h, lung rales were risk factors for influenza A viral pneumonia (P＜0.05). CONCLUSION The incidence of influenza A viral pneumonia in children is relatively high, with the main symptoms of mild pneumonia, lesions in both lungs, and combination of bacterial infection. Men, children with a long time from onset to first visit or antiviral treatment, and lung rales had a higher risk of developing the disease. Therefore, targeted preventive interventions and treatment measures could be given accordingly.
