摘要: 目的 了解西安市城区在关闭活禽交易市场后居民人感染H7N9禽流感暴露风险,为制定H7N9禽流感防控策略提供依据。方法 采用多阶段抽样法,选取调查对象,采用面对面访谈方式,收集被调查者过去一年的活禽购买数量、购买行为、H7N9禽流感相关知识掌握情况及就诊习惯等信息。结果 完成调查问卷624份,其中30.77%(192/624)的被调查者过去一年购买过活禽,平均购买数量为1.1只,13.78%(86/624)的调查者在购买活禽时有直接触摸活禽或禽笼等行为,西安市城区居民人均暴露频次为0.15次。H7N9禽流感相关知识总体知晓率为70.38%(2 635/3 744),其中"发病早期表现"知晓率最低,为60.90%(380/624)。12.02%(75/624)的被调查者过去一年出现过流感样症状,29.33%(22/75)的病例选择了主动就诊。结论 虽然西安市城区取缔了活禽交易,但仍存在暴露风险,需进一步加强健康宣传。Abstract: Objective To understand the exposure risk of human infection with avian influenza A (H7N9) among urban residents in Xi'an, Shaanxi. Methods A cross-sectional study was conducted in urban areas of Xi'an. Participants were selected by multistage sampling. We collected information on human exposure to poultry, related knowledge of human infection with avian influenza A (H7N9) and treatment after influenza-like symptoms occurred. Results Among 624 participants investigated, 192(30.77%) purchased live poultry during the past year. 86(13.78%) touched directly live poultry or poultry cage. We estimated that the mean number of live poultry purchased per year was 1.1 among urban residents in Xi'an. The exposure frequency was 0.15 per person. The overall awareness rate of knowledge on influenza A(H7N9) was 70.38% (2 635/3 744). The awareness of "Early symptoms" was the lowest (60.90%). Among 75(12.02%) participants who had influenza-like symptoms, only 22(29.33%) choosed to see the doctor directly. Conclusions The urban residents in Xi'an had exposure risk of human infection with avian influenza A (H7N9) in certain degree. Health education for the residents should be strengthened.
