ABSTRACT
OBJECTIVE: To investigate and analyze multiple detection of 13 kinds of viruses in 500 children with acute respiratory tract infection in Hami of Xinjiang. METHODS: A total of 500 children with acute respiratory tract infection treated in the hospital between Jan 2018 and Jan 2021 were enrolled. Thirteen kinds of respiratory infection viruses including human respiratory syncytial virus(RSV), human rhinovirus(hRV), respiratory adenovirus(AdV), influenza A and B viruses(Inf A, Inf B), parainfluenza virus(PIV 1/2/3), human enterovirus(hEV), human metapneumovirus(hMPV), human coronavirus(hCoV 229E/OC43) and human Boca virus(hBoV) were detected by multiple reverse transcription polymerase chain reaction(RT-PCR) amplification and capillary electrophoresis. And the results were compared with those by direct sequencing method. RESULTS: Of the 500 samples, 379 samples were positive(75.80%), and the top three detection rates were RSV(19.40%), hRV(16.00%) and Inf B(12.60%). The differences in positive rates of the respiratory virus among <1 year group, 1-3 years group and >3 years group were significant(84.97%, 77.47%, 65.45%)(P<0.05). The detection rate of RSV was the highest in <1 year group, and the detection rates of Inf A and Inf B were the highest in >3 years group. The differences in positive rates of respiratory viruses among the spring group, summer group, autumn group and winter group were significant(74.05%, 63.73%, 77.24%, 84.03%)(P<0.05). The detection rates of RSV, PIV 3, and hMPV were the highest in the winter group, and detection rate of AdV was the highest in spring group. CONCLUSION: RSV is the main infection virus in children with acute respiratory infection in Hami of Xinjiang. The distribution of respiratory viruses is related to age and onset season in children.
