ABSTRACT
Objective To analyze the epidemiological characteristics of influenza in preschool children in Leshan City from 2016 to 2018, and to compare the difference between antigen colloidal gold reagent and nucleic acid detection reagent. Methods A total of 1 100 patients with suspected influenza admitted to Leshan City from January 2016 to December 2018 were selected as the research objects; the clinical data and characteristics of influenza epidemiology of the patients were collected, and the antigen colloidal gold reagent and nucleic acid detection reagent were used to detect influenza. Epidemiological characteristics; using nucleic acid detection as the standard to evaluate the diagnostic value of antigen colloidal gold reagent detection methods. Results The nucleic acid detection gold standard, antigen colloidal gold reagent method to detect influenza The sensitivity and specificity of the pathogen are both greater than 80%, and the AUC of influenza pathogen detection by the antigen colloidal gold reagent method is greater than 0.90, which has high application value . From 2016 to 2018, Leshan City was dominated by type B Y and type A H3N2; the main clinical features were cough, runny nose, and fever (P<0.05); the distribution of characteristics showed that there was no statistics on the sex of children with influenza Significantly, children less than 5 years old accounted for the highest proportion, and the proportion of children in winter and Spring Festival was significantly higher than that in summer and autumn, and the difference was statistically significant (P<0.05). Conclusion From 2016 to 2018, influenza virus infections in preschool children in Leshan City were mainly type Y and type A H3N2, and showed obvious age and seasonal characteristics. The antigenic colloidal gold reagent was used in clinical screening for children, but the test was negative. Children who are at high risk should be diagnosed with nucleic acid method as soon as possible.
