Objective: To understand the epidemiological features of Mycoplasma pneumoniae (MP) in children from May 2009 to April next year in Lishui City, and to provide basis for the prevention and treatment of MP infection. Methods: The clinical data of 741 hospitalized children with acute lower respiratory tract infection under 15 years old in our hospital were retrospectively analyzed. The incidence of MP in children of different seasons and ages were statistically analyzed. Results: The positive number of MP in 741 cases was 253 cases, the positive rate was 34.1%. The peak incidence was in February-March and October-December, and the incidence was low in May-August. Higher and higher, 10-year-old to 15-year-old incidence of up to 45.7%, followed by 6-year-old accounted for 43.8%. Conclusion: MP infection has become a common pathogen of acute lower respiratory tract infection in children. The incidence is closely related to age and season.
