Objective:To investigate the detection, epidemiological and clinical characteristics of human rhinovirus(HRV) in hospitalized children with respiratory tract infections.Methods:The study population comprised of 10 514 children with respiratory tract infections admitted to Department of Respiration, the Children′s Hospital of Soochow University, between January 2013 and December 2019.The nasopharyngeal aspirates and medical history were obtained by qualified medical personnel.Reverse transcription-polymerase chain reaction method was used to test HRV.Results:The total positive rate of human rhinovirus was 14.2%(1 493/10 514), and there was no significant difference between male and female( χ2=2.006, P=0.157). The positive rates from 2013 to 2019 were 9.7%, 14.6%, 19.1%, 18.6%, 18.1%, 11.0%, 11.4% respectively, and there were significant differences among these groups( χ2=116.580, P<0.001). HRV distributed throughout the year with a peak in summer and autumn(June to November), followed by spring, and the lowest in winter.The detection rates of HRV infection rates were 14.2%, 15.5%, 13.5% and 9.8% in the age group of 28 d~6 months, ~2 years, ~7 years and>7 years respectively, and there were significant differences among these age groups( χ2=16.124, P<0.001). The detection rate of HRV in children under 2 years was higher( χ2=7.711, P=0.005). The clinical characteristics of HRV infection were fever, cough, wheezing and even dyspnea.Bronchopneumonia had the highest percentage(68.9%), followed by bronchitis(13.2%). Compared with non-coinfection group, patients with coinfection with other viruses were more prone to wheezing and pulmonary rales( χ2=9.483, 10.821, P=0.024, 0.013), and coinfection with mycoplasma was more likely to cause fever and lobar pneumonia( χ2=51.585、96.060, P all<0.001); 57.8% presented leukocytosis, while 15.6% showed a higher CRP(>15 mg/ml). The increase of CRP and leukocytosis were more obvious in children under 2 years of age( χ2=26.097, 55.973, P all<0.001). Conclusion:HRV was a major viral pathogen of RTIs in recent 7 years, distributing throughout the year with a peak in summer and autumn, mainly involving children under 2 years of age.The clinical features were diverse, and the clinical symptoms were severe in childhood coinfections with other pathogens.
