[Abstract]:Objective to analyze the pathogenic types and epidemiological characteristics of influenza surveillance in Wenzhou from 2009 to 2014, so as to provide the basis for the prevention and control of influenza. Methods Real-time fluorescence quantitative PCR was used to detect (ILI) nasopharynx swabs collected from influenza surveillance sentinel hospitals, and the results were statistically analyzed. Results from 2009 to 2014, there were 7,885,356 cases monitored in Sentinel Hospital, of which 151 (3.69%) were ILI 291,684 (14.47%) were positive in 6 years. Type B was the most common type of influenza, and the positive rate was 14.47% in Sentinel Hospital during the period of 2009 to 2014, in which 4 726 (3.69%) were detected in Sentinel Hospital. The new type of H1N1 was the second; Among the 5 age groups, the positive rate of 6-15 years old group was the highest (27.10%). Conclusion the epidemic rate of influenza virus in 6 years in this city is high in winter, high in spring and accompanied with small peak in summer, the main epidemic types are type B, new type H1 N1 and genotype H 3 alternately, influenza surveillance and prevention and control have made some achievements in the surveillance and prevention and control of influenza.
