Abstract:

Objective: To analyze the detection,etiological types and epidemic characteristics of human rhinovirus(HRV)in the hospitalized children with respiratory syndrome in Chengdu area during 2011—2013,and to provide basic data for prevention and control HRV infection.Methods: Altogether 1 117 nasopharyngeal aspirate samples were collected regularly from the children with respiratory syndrome. The samples were screened for the presence of RNA of HRV-5'NCR using RT-PCR.HRV specific sequence types and mutation status were identified by sequencing the VP4/VP2 coding region.Results: A total of 24.62%(275/1 117)of these samples were positive for HRV RNA.30 sequences were obtained,including 15 HRV-As,4 HRV-Bs and 11 HRV-Cs.The HRV detection peak was in November,and in different age groups,the detection rate for children under 1 years of age was higher than others.The highest detection rate of HRV was in the children with asthmatic diseases among different clinical diagnosis diseases.Conclusion: HRV is a common pathogen of viral infection in the hospitalized children with respiratory syndrome and it can be detected throughout the year in Chengdu area.The differences in detection rate between different genders and different seasons are satistically significant.Sequence analysis showed that multiple genotypes of rhinovirus are epidemic in common in Chengdu area and HRV-A is the main subtype.
