Abstract：Objective To analyze the epidemiological characteristics of respiratory syncytial virus(RSV)infection among 15,552 hospitalized children with respiratory infections in Tianjin from November 2015 to October 2024,and to provide a basis for the prevention and treatment of RSV.Methods Data on RSV antigen detection from 15,552 hospital-ized children with respiratory infections in Tianjin from November 2015 to October 2024 were collected.The epidemiologi-cal characteristics of RSV infection were analyzed based on the age,gender,month of onset,season,and year of the chil-dren.Results Among the 15,552 children with respiratory infections,the overall positive rate of RSV antigen detection was 14.01%.When stratified by gender,there was no statistically significant difference in the positive rate of RSV antigen detection between male and female children(P>0.05).When stratified by age,the highest positive rate was observed in children aged 0-<7 months,followed by those aged 7 months to<1 year and 1-<2 years.The differences in positive rates among different age groups were statistically significant(all P<0.05).When stratified by month of onset,the positive rate of RSV antigen detection was greater than 17%from November to March,while it dropped significantly in other months.The differences in positive rates among different months were statistically significant(all P<0.05).When stratified by sea-son,the positive rate of RSV antigen detection was the highest in winter,followed by spring,then autumn,and the lowest in summer.The differences in positive rates among different seasons were statistically significant(all P<0.05).When stratified by year,the differences in positive rates among different years were also statistically significant(all P<0.05).Conclusions Among the 15,552 hospitalized children with respiratory infections in Tianjin from November 2015 to Oc-tober 2024,there was no gender difference in RSV infection.Infants aged 0-<7 months were at the highest risk.The peak incidence period was from November to March each year,with the highest incidence in winter.The period from No-vember 2017 to October 2018 had the highest positive rate compared to other years.
