Respiratory pathogen distribution characteristics in children with acute respiratory disease / 国际检验医学杂志

ABSTRACT

Objective To investigate the respiratory pathogen distribution characteristics in children with acute respiratory disease(ARD).Methods Distribution of respiratory pathogen in 28 600 children with ARD,treated from January 2011 to December 2014 in this hospital,were analyzed.Results Among the 28 600 children,12 162 cases were pathogen positive,including 7 704 cases(63.34%) with single pathogen infection and 4 458 cases(36.66%) with more than two kinds of pathogens infection.Time,season,sex and age distribution of pathogen infection were with statistical difference(P<0.05).There was significant difference in infection rate of pathogens between different time(P<0.05).Infection rate of Mycoplasmal pneumonia(MP) was the highest,and the infection rate of MP and influenza B virus(IFB) increased year by year.Except Legionella pneumophila(LP),the season distribution of infection rate of MP,Coxiella burneti(COX),Chlamydia pneumoniae(CP),adenovirus(ADV),respiratory syncytial virus(RSV),influenza A virus(IFA),IFB and parainfluenza virus(PIVs) were with statistical difference(P<0.05).The infection rate of MP and IFB were higher in the whole year.Conclusion Distribution of respiratory pathogen in children with ARD might be related with the changes of gender,age and season.Detection of respiratory infection pathogen could be with guiding value for clinical diagnosis and drug selection.
