Objective To understand the change characteristics of respiratory pathogens in hospitalized children with respiratory tract infection in Shunyi district of Beijing from 2019 to 2020, and to provide basis for the prevention and treatment of respiratory tract diseases in children.
Methods The case information of hospitalized children with respiratory infection in Shunyi district hospital from 2019 to 2020 was collected. The age, gender and IgM antibody test results of respiratory pathogens (rickettsia, mycoplasma pneumoniae, respiratory syncytial virus, chlamydia pneumoniae, influenza A virus, influenza B virus, parainfluenza virus, legionella pneumophila and adenovirus) were entered by Excel 2007. SPSS 22.0 was used for statistical analysis. Chi square test was used to compare the detection rate of respiratory pathogens in different years, seasons and age groups.
Results There were 1 791 hospitalized children with respiratory infection in Shunyi district hospital from 2019 to 2020, including 1 061 cases in 2019 and 730 cases in 2020. The IgM antibody of single pathogen was positive in 937 cases (52.76%, 937/1 791), mainly mycoplasma pneumoniae (22.97%, 414/1 791), influenza B virus (12.44%, 224/1 791) and parainfluenza virus (11.77%, 223/1 791), rickettsia was not detected. Compared with 2019, the detection rates of respiratory syncytial virus and adenovirus increased in 2020, while the detection rates of the other six pathogens decreased. The detection characteristics of different pathogens varied with seasons. In different age groups, the detection rate of pathogens in <1 year (12.50%), 1– year (42.63%), 3– year (59.90%) and ≥ 7 year (65.06%) groups increased in turn.
Conclusion The ≥3 year children, mycoplasma pneumoniae and virus infection are the focus of children's respiratory infection prevention and control; the children's respiratory infection prevention and control should be paid attention in different seasons.
