Abstract:
Early, rapid and accurate diagnosis of disease is of great significance for the prevention of disease progression and the best clinical rational treatment program. Respiratory tract infections are the common and frequently occurring diseases in infants and preschool children. About 90 percent of upper respiratory tract infections are caused by viruses, and followed by secondary bacterial infections. Bacterial pathogen often causes lower respiratory tract infections. This study describes the clinical features of typical pathogens of respiratory tract infections in children including respiratory syncytial virus, influenza virus, coronavirus and atypical pathogens-mycoplasma, chlamydia and legionella, and explains the clinical testing evaluation of widely used PCR method in the detection and diagnosis of respiratory tract infections in children. Finally, we analyzed the advantages and disadvantages of current used respiratory pathogen detection method-traditional culture method, based on pathogen antigen (antibody) assay and nucleic acids method.
