This study aimed to estimate influenza-like illness (ILI) prevalence, influenza-related healthcare seeking behaviors, and willingness for vaccination.
A retrospective cross-sectional study based on a random dialing telephone survey was conducted from October 2017 through March 2018 to assess influenza-like illness prevalence and vaccination willingness among different demographic groups.
10,045 individuals were enrolled and completed the survey. A total of 2834 individuals (28%) self-reported that they have suffered from influenza-like illness, especially children under 15 years of age. Overall willingness for influenza vaccination in the 2018/2019 influenza season was 45% and was positively associated with higher education level, recommendation from doctors, cost-free vaccination, and vaccination campaigns with employers' support. Hospitalization and seeking medicine from pharmacies was less frequent in urban locations. People under 15 and over 60 years of age sought medical service more frequently.
ILI prevalence differed significantly by age and geographical location/population density. Vaccination policy for motivating key populations at highest risk to vaccinate should take into consideration the awareness-raising of vaccination benefits, barriers reduction of vaccination such as cost, and recommendation via healthcare professionals.
本研究旨在估计流感样疾病（ILI）的患病率、与流感相关的就医行为以及接种疫苗的意愿。
2017年10月至2018年3月进行了一项基于随机拨号电话调查的回顾性横断面研究，以评估不同人口群体中流感样疾病的患病率和接种疫苗的意愿。
10045人参与并完成了调查。共有2834人（28%）自我报告曾患流感样疾病，尤其是15岁以下儿童。2018/2019流感季节总体流感疫苗接种意愿为45%，且与较高的教育水平、医生建议、免费接种以及在雇主支持下的接种活动呈正相关。城市地区住院和在药店购药的情况较少见。15岁以下和60岁以上人群就医更频繁。
流感样疾病患病率在年龄和地理位置/人口密度方面存在显著差异。激励高危重点人群接种疫苗的政策应考虑提高对疫苗接种益处的认识、减少接种障碍（如费用）以及通过医疗专业人员进行推荐。
