Abstract:
Objective:To explore the clinical features of Mycoplasma pneumoniae(MP)infection in children, and provide data support for the prevention and control of MP.Methods:In this study , a retrospective analysis was used to collect clinical data with respiratory tract infection from January 2018 to February 2022 in the Shenyang Children′s Hospital, and analyze the distribution characteristics of MP positive rate, season, age, sex.Results:In this study, the positive rate of MP was 17.12% (20 299/118 598), in 2018, 2019, 2020 and 2021 were 22.92% (7 732/33 738), 15.76% (5 736/36 388), 9.81% (1 313/13 379) and 16.60% (4 954/29 849) respectively.The highest positive rates of MP in 2018 and 2019 were 27.72% (1 809/6 527) and 23.45% (1 519/6 478) in summer, respectively, 2020 was spring (19.13%, 216/1 129) and 2021 was autumn (20.09%, 1 665/8 287).The MP positive rates of infancy, early childhood, preschool age and school age were 5.89% (605/10 265), 14.35% (4 639/32 333), 18.51% (10 961/59 203) and 24.37% (4 094/16 798), and MP positive rate increased with age, the difference was statistically significant ( χ2=1 790.971, P<0.05).The positive rate of boys was 14.70% (9 586/65 206), while that of girls was 20.06% (10 713/53 392), the difference was statistically significant ( χ2=594.937, P<0.05). Conclusion:MP can occur all years round, mainly in summer and autumn.Girls are susceptible, especially common in school-age and pre-school children.Prevention and control measures should be taken as soon as possible for susceptible individuals to reduce the infection rate of MP.
