Abstract:
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 22 755 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.
