Abstract:Objective: To analyze the epidemiological characteristics of mycoplasma pneumonia (MP), chlamydia pneumonia (CP) and legionella pneumophila (LP) in children with recurrent respiratory tract infections (RRTIs). Methods: A total of 186 children with RRTIs admitted to the hospital between September 2017 and September 2021 were enrolled in the study. The whole blood was collected to detect IgM antibodies of serum MP, CP and LP. And the screening results were analyzed. Results: The positive rate of serum MP was higher than that of CP (31.72% vs 19.89%) (P<0.017, Bonferroni correction). The positive rate of CP was higher than that of LP (19.89% vs 8.06%) (P<0.017, Bonferroni correction). There was no significant difference in positive rates of serum MP, CP and LP among children of different genders (P>0.05). The positive rates of serum MP, CP and LP in RRTIs children aged 3-6 years were 51.32%, 34.21% and 17.11%, higher than those aged 0-2 years (13.64%, 9.09%, 2.27%) and 7-12 years (21.21%, 10.61%, 1.52%) (P<0.017, Bonferroni correction). The positive rates of serum MP, CP and LP in winter were 58.54%, 41.46% and 24.39%, higher than those in spring (25.49%, 13.73%, 3.92%), summer (17.95%, 12.82%, 2.56%) and autumn (27.27%, 14.55%, 3.64%) (P<0.0083, Bonferroni correction). Conclusion: Among children with RRTIs, MP, CP and LP had the highest rate of positivity, followed by CP infection, and LP was the lowest. There is no significant difference in the three infections among children of different genders. However, there are differences in their susceptibility among children at different age groups. There are seasonal differences in the prevalence of pathogens.
