Epidemiological investigation of Mycoplasma Pneumoniae and Chlamydia Pneumoniae infection in patients with acute respiratory tract infection
Objective To investigate the epidemiological characteristics of Mycoplasma Pneumoniae(MP)and Chlamydia Pneumoniae(CP)infection in patients with acute respiratory tract infection in this area.Methods The results of serum MP and CP immunoglobulin M(IgM)antibodies in 4 896 patients with acute respiratory tract infection who were 1 day to 102 years old and treated in Chenggong Hospital Affiliated to Xiamen University from February 2021 to August 2023 were retrospectively analyzed.There were 2 886 males and 2 010 females.The results were analyzed by the x2 test to compare the infection types,populations,and seasonal distribution characteristics of MP and CP.Results The positive rate of MP-IgM and CP-IgM antibodies in the patients with acute respiratory infection from 2021 to 2023 was 14.48％(709/4 896);the positive rate of MP was 12.58％(616/4 896);the positive rate of CP was 1.63％(80/4 896);the positive rate of MP+CP was 0.27％(13/4 896);MP infection was the main infection.The positive rate of MP in the females was higher than that in the males[17.31％(348/2 010)vs.9.74％(281/2 886)],with a statistical difference(x2=60.748,P＜0.001).There was no statistical difference in the positive rate of CP between the females and the males(x2=0.360,P＞0.05).There were statistical differences in the infection rates of MP and CP between the different age groups(x2=237.938 and 55.070,both P＜0.05).MP mainly infected the 0～14 years old children,and CP the 6-40 years old.The total positive rates of MP[15.30％(268/1 752)]and CP[2.40％(42/1 752)]in summer were higher than those in other seasons.There was a statistical difference in the total positive rate of MP between different seasons(x2=16.747,P＜0.001),with a high incidence in summer and autumn.There was no statistical difference in the total positive rate of CP between different seasons(x2=4.114,P=0.249).Conclusions MP and CP are important pathogens of acute respiratory diseases;among which,MP is the main infection,showing seasonal,gender,and age differences.
