Abstract:
Objective To understand the pathogens distribution situation in children with acute respiratory tract infection (ARTI) in Bozhou area.Methods A total of 2 846 children with ARTI in our hospital from April 2015 to March 2016 were enrolled to investigate the pathogens distribution.The indirect immunofluorescence assay was performed to detect adenovirus,influenza virus A,influenza virus B,respiratory syncytial virus,parainfluenza virus,mycoplasma pneumoniae,chlamydophila pneumoniae and legionella pneumophila in peripheral blood samples.Results Of all 2 846 cases,1 161 (40.8％) cases were the pathogen detection positive.Among them,the top 3 viruses of highest detection rates were mycoplasma pneumoniae(470,16.5 ％),influenza virus A (252,8.9％) and respiratory syncytial virus (117,4.1％),and 79(2.8％) cases were mixed infection.With age increase,the pathogen detection rate showed the declining trend(x2 =20.724,P=0.000 1).The infections in infants and young children were dominated by respiratory syncytial virus(11.2 ％),which in preschool and school children was dominated by mycoplasma pneumoniae(15.2 ％-25.4 ％).The pathogen detection rate was highest in winter (57.7 ％),and lowest in summer (22.5 ％).Conclusion The prevalence distribution of ARTI pathogens varies with age and seasons.The infection rate in infants and young children is higher than that in other age groups.Mycoplasma pneumoniae,influenza virus A and respiratory syncytial virus are the main pathogens causing ARTI in children of Bozhou area,winter and summer have ARTI high onset,it is notable to strengthen the prevention of infection.
