Abstract:
Objective To investigate the detection of respiratory tract virus from throat swabs of patients with lower respiratory tract infection(LRTI)in a hospital,so as to provide reference for clinical diagnosis and treatment. Methods Throat swabs of hospitalized children with LRTI between May 2103 and April 2014 were detected by di-rect immunofluorescence assay,infection/carriage of respiratory syncytial virus(RSV),adenovirus(ADV),influen-za virus A(IV-A),IV-B,parainfluenza virus 1(PIV-1),PIV-2,and PIV-3 in children were surveyed.Results Of 8 425 throat swab specimens of hospitalized patients,1 879 were detected virus,the total detection rate was 22.30%,detection rate of RSV was the highest (11 .31 %),followed by PIV-3(4.37%).There was no significant difference in the total detection rate of respiratory tract virus between children of different genders (P =0.051).Of all age groups,detection rate of RSV in infants and young children was the highest,the detection rates of 7 kinds of virus from preschool children were approximate,detection rate of ADV from primary school children was the high-est (37.50%).In spring and winter,children mainly infected with RSA,accounting for 62.82% and 69.88% re-spectively;in summer,PIV-3 was the predominant virus,accounting for 41 .47%,in autumn,there was little difference in the percentage of each virus.Conclusion The detection rate of 7 kinds of virus isolated from throat swabs of hospitalized children with LRTI is related to age and season;the detection rate of 7 kinds of virus from in-fants and young children is high,RSA is the main virus.
