Abstract
Objective To analyze the epidemiological characteristics and etiological distribution of children with influenza(flu).Methods The throat swab specimens of 394 children aged 1 to 10 years old who were diagnosed with influenza at the First People's Hospital of Xiangfu District,Kaifeng City from March 2020 to February 2023 were included.The samples were analyzed by real-time fluorescence quantitative polymerase chain reaction to complete influenza virus detection and analyze the virus types and distribution of age,season,gender,year,etc.among these 394 children with influenza were analyzed.Results Influenza A H1N1 virus was the influenza virus with the highest proportion detected in this study,accounting for 36.04%;there were differences in the proportions of influenza A H3,A H1N1,BV,and B BY influenza viruses between male and female children,with no statistical significance(P＞0.05);the proportion of children with influenza is the largest in spring and winter,41.12%and 35.53%respectively,and proportions of influenza A H3,A H1N1,B BV,and B BY influenza in different seasons were significantly different(P＜0.05).Children aged 7 to 10 accounted for the highest proportion of influenza patients,42.13%.Among children of different ages,the proportion of influenza A H3,A H1N1,B BV,B BY had no statistically significant difference(P＞0.05).The proportion of children with influenza in 2020 was the highest at 43.40%,followed by 29.70%in 2022 and 26.90%in 21;in different years there is a statistically significant difference in the proportion of children with influenza in winter(P＜0.05).There is no statistically significant difference in the proportion of children with influenza of all ages in different years(P＞0.05).The preportions of influenza A H3 and A H1N1,B BV and B BY viruses in each year,had no statistically significant difference(P＞0.05).Conclusions Children aged 7 to 10 years old are a high-risk group for influenza,and influenza A is the main type of infection in children.Influenza A viruses are more common in spring and winter.Changes in prevention and control policies during the new coronavirus pneumonia epidemic have an impact on the epidemic of influenza.Therefore,prevention of influenza A for children aged 7 to 10 years old in spring and winter should be strengthened.关键词
