Abstract

Abstract: Objective To explore the epidemiological characteristics of lower respiratory Mycoplasma pneumoniae (MP) infection in children so as to provide data for the prevention and treatment of MP infection in children. Methods The clinical data of 1134 children with lower respiratory infection (LRI) in Hubei Maternal and Child Health Hospital from January 2017 to December 2019 were collected. Based on retrospective research method, the unified clinical research forms were formulated to read the clinical data of children in detail. The related data were collected and summarized, including gender, age, admission time, clinical symptoms and test results of MP antibody. Results Among the 1134 LRI children from 2017-2019, there were 155 cases (13.67%) with positive MP. The ratios of MP infection in 2017, 2018 and 2019 were 14.40%, 11.17% and 15.49%, respectively. And the difference was not statistically significant (P>0.05). The ratios of MP infection in males and females were 13.11% (78/595) and 14.29% (77/539), and the difference was not statistically significant between the groups (P>0.05). The ratio of MP infection was gradually increased with age. The ratio of MP infection was the lowest in LRI children aged 0-3 years (10.26%), followed by 4-5 years old (15.41%) and 6-14 years old (16.44%). After comparison, ratio of MP infection in LRI children aged 0-3 years was significantly lower than that aged 4-5 years old and 6-14 years old (P<0.05). There was MP infection throughout the year, with the highest ratio of MP infection within October-December (17.21%), followed by January-March (14.01%), April-June (10.67%) and July-September (9.28%). After comparison, ratio of MP infection within October-December was significantly higher than that within April-June and July-September (P<0.05). Conclusion Children aged 4-14 years old are the susceptible population. The main symptoms include cough, fever and wheezing. And the disease is more likely to appear in autumn and winter.
