Abstract:
Objective To explore the epidemiological characteristics of mycoplasma pneumoniae (MP) infection in hospitalized children between 2019 and 2022, and to provide a basis for the prevention and treatment of the disease in the clinic. Methods Blood samples of 12 830 children hospitalized for respiratory tract infection in our hospital between January 2019 and December 2022 were collected, and tested for MP infection, then the prevalence of MP infection in different years, seasons, genders and ages was analyzed. Results The total positive rate of MP was 16.55% (2 123 / 12 830). The annual prevalence rate of MP infection decreased from 17.97% in 2019 to 16.48% in 2022, with statistical difference (P<0.05). In terms of gender, the prevalence of MP infection was higher in females at a rate of 19.38% (1 198 / 6 182) compared with a rate of 13.91% (925 / 6 648) in males, with statistical difference (χ2=69.277, P<0.05).The positive rates in summer (19.84%) and autumn (19.57%) were higher than those in spring (12.97%) and winter (12.38%) (P<0.05) In terms of age, the positive rate of MP infection was 9.68% in < 1 age group, 12.95% in 1-3 age group, 18.23% in 4-6 age group and 23.23% in > 6 age group (P<0.05), with the highest positive rate in > 6 age group. The positive rate of MP infection was 15.49% in acute upper respiratory tract infection , 17.28% in acute lower respiratory tract infection , 16.43% in severe pneumonia, and 16.71% in other diseases, with no statistical difference (P>0.05). Conclusion MP is one of the main pathogens of respiratory infections in hospitalized children. Despite the decreasing trend in MP infection rate in hospitalized children between 2019 and 2022, it remains above the norm. MP infection is characterized by a high prevalence in summer and autumn, children >6 years of age, and girls, so effective measures should be taken to guide clinical anti-infection strategies to improve the physical and mental health of children in this region.
