Abstract：Objective To analyze the etiological examination of children with acute respiratory tract infection in Chifeng area of Inner Mongolia Autonomous Region,and to provide reference for clinical treatment.Methods The clinical data of 1 096 children with acute respiratory tract infection(including 639 males and 457 females)in Chifeng Songshan Hospital from July 2024 to March 2025 were reviewed and analyzed,including age,gender and detection rates of influenza A virus(INFA),influenza B virus(INFB),Mycoplasma pneumoniae(MP),adenovirus(ADV),respiratory syncytial virus(RSV)and human rhinovirus(HRV)in throat swabs.They were divided into bronchitis group(376 cases),pneumonia group(306 cases),upper respiratory tract infection group(139 cases)and bronchial asthma group(75 cases)according to type of infectious disease.According to age,the children were divided into 1-3 years old group(328 cases),4-6 years old group(374 cases)and 7-13 years old group(394 cases).They were divided into winter and spring group(829 cases)and summer and autumn group(267 cases)according to the onset season.The detection rates of different pathogens in each group were analyzed and compared.Results The detection rate of INFA in children with upper respiratory tract infection was the highest(58.27%),and that of MP in children with pneumonia was the highest(75.16%).The detection rate of ADV in males was significantly higher than that in females(7.51%vs.3.50%,P<0.05).The detection rates of INFA,INFB,MP,RSV and ADV in different age groups were significantly different.The detection rates of MP and RSV in winter and spring were significantly higher than those in summer and autumn,and that of INFB in winter and spring was significantly lower than that in summer and autumn(MP:39.32%vs.37.51%;RSV:6.51%vs.4.38%;INFB:2.41%vs.5.24%;all P<0.05).Conclusion MP and INFA are the main pathogens of respiratory tract infection in Chifeng area,and MP is mainly found in children aged 7-13 years old and detected in winter and spring.
