Abstract: [Objective] To estimate the residents’ influenza vaccination rate, incidence of influenza-like illness（ILI）, and related influencing factors in Jiaxing City. [Methods] Using stratified random sampling, totally 7 215 residents in Jiaxing City were enrolled to a household-based questionnaire survey, and 6 765 valid questionnaires were obtained to analyze ILI incidence and vaccination coverage. [Results] The standardized incidence of ILI was 20.96%, and the standardized vaccination rate of influenza was 12.43%. Age, season, sports activity, influenza vaccination, history of chronic diseases, and pregnancy were statistically associated with the ILI incidence（P ＜ 0.05）. Specifically, the risks of ILI incidence were elevated in young ages, winter and spring, and the residents with no sports activity, no influenza vaccination within past one year, having a history of chronic diseases, and being pregnant, while sex and resident region was not statistically associated with ILI. [Conclusion] The overall influenza vaccination rate is low, and the incidence of ILI is on the high side. Various factors may contribute to the elevated incidence rate. Therefore, besides increasing the vaccination coverage, other appropriate prevention and control measures against the influencing factors for ILI are also required to reduce the incidence of ILI in Jiaxing.
