【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 investigate the exposure risk of H7N9 avian influenza in residents of Xi'an city after closing the live poultry market, and to provide evidence for the formulation of H7N9 avian influenza prevention and control strategy. Methods Multi-stage sampling method was used to select the survey subjects, and face-to-face interviews were used to collect the information on the quantity of live poultry, purchasing behavior and H7N9 avian influenza related knowledge and visiting habits in the past year. Results 624 questionnaires were completed, of which 30.77% (1922 / 624) of the respondents had purchased live poultry in the past year. The average purchase quantity was 1.1 per cent (86 / 624) who had direct contact with live poultry or cages when buying live poultry. The per capita exposure frequency of Xi'an urban residents was 0.15 times. H7N9 avian influenza related knowledge rate was 70.38% (2 635 / 3 744), among which the awareness rate of "early onset" was the lowest. For 60.90% (380 / 624), 12.02% (75 / 624) of the respondents had flu like symptoms in the past year, 29.33% (22 / 75) of the cases chose an active visit. Conclusion although the live poultry trade has been banned in Xi'an urban area, there is still a risk of exposure, and health publicity needs to be further strengthened.
