Abstract：Objective To analyze the epidemiological characteristics of influenza surveillance cases so as to provide evidence for nosocomial infection control measures. Methods A total of 520 influenza-like patients in the pediatric outpatient and emergency departments and inpatients of Peixian Hospital of Traditional Chinese Medicine from January to December 2021 were selected and their clinical data, and nasal and throat swab test results were analyzed for influenza A/B virus antigen detection. Results Among 520 influenza-like cases, the influenza virus antigen test was positive in 56 cases, and the positivity rate was 10.77%, in which the positive rates of influenza A and B antigens were respectively 0.96% and 9.81%, and the difference was statistically significant (χ2＝39.936, P<0.001). The positive rate of the 0-5 years old group was 13.41%, the positive rate of the 6-15 years old group was 5.33%, and no positive test was detected in the group over 16 years old, and the difference was statistically significant (χ2=7.026, P=0.013). Influenza cases were mainly concentrated in January and October-December, and the time distribution of incidence was statistically significant (χ2=19.746, P=0.048). Conclusion The surveillance of influenza-like cases in Peixian Hospital of Traditional Chinese Medicine in 2021 showed that the influenza B virus is the main one, with the peak incidence in January and October to December, and there is a risk of nosocomial infection or even outbreak, and effective infection control measures are needed to prevent nosocomial infection.
