摘　　要：目的了解杭州地区急性呼吸道感染儿童中呼吸道合胞病毒(respiratory syncytial virus,RSV)的核酸阳性检出情况及流行特征。方法收集整理2017年1月至2022年12月杭州市儿童医院检出的RSV核酸阳性患儿的信息,对年龄、性别、检出时间等因素进行回顾性分析。结果累计送检样本22755例,其中RSV病例4079例,总阳性检出率17.93%,历年总体呈现不断波动的感染特征。性别方面,男童RSV阳性检出率10.36%,女童7.57%,男女比例为1.36∶1,差异有统计学意义(P<0.05);年龄上,<1岁的婴幼儿阳性检出2378例,占所有阳性检出患儿的58.30%,<3岁患儿占比94.93%,不同年龄段患儿的RSV阳性检出率随年龄增大呈下降趋势;季节方面,RSV在秋、冬季高发,两季检出率占比83.82%,春、夏季检出率仅为16.18%,秋、冬季节的RSV阳性检出率显著高于春、夏季(P<0.05)。结论杭州地区历年急性呼吸道感染患儿中,RSV感染呈波动趋势,且秋、冬季高发,婴幼儿及男童阳性检出率较高,应注意在相应季节的重点人群的防护。Objective To investigate the positive nucleic acid detection of respiratory syncytial virus(RSV)in children with acute respiratory tract infection in Hangzhou.Methods The information of RSV nucleic acid positive cases detected in Hangzhou Children’s Hospital from January 2017 to December 2022 was collected and analyzed retrospectively by age,gender,detection time and other factors.Results A total of 22755 samples were sent for examination,among which 4079 cases of RSV were reported,with a total positive detection rate of 17.93%,showing constant fluctuation of infection over the years.In terms of gender,the positive detection rate of RSV was 10.36% in boys and 7.57% in girls,and the ratio of male to female was 1.36:1,the difference was statistically significant(P<0.05).In terms of age,there were 2378 positive cases in infants<1 year old,accounting for 58.30% of all positive cases,and 94.93% in infants<3 years old.The positive detection rate of RSV in children of different age groups showed a decreasing trend with the increase of age.In terms of seasons,RSV occurred frequently in autumn and winter,and the detection rate in two seasons was 83.82%,while the detection rate in spring and summer was only 16.18%.The positive detection rate of RSV in autumn and winter was significantly higher than that in spring and summer(P<0.05).Conclusion RSV infection fluctuates in children with acute respiratory tract infection in Hangzhou over the years,and the incidence is high in autumn and winter.The positive detection rate is high in infants and boys.Attention should be paid to the protection of key populations in corresponding seasons.
