Abstract

Since March 2013, China had experienced five seasonal epidemics related to Avian influenza A (H7N9). An unprecedented outbreak of H7N9 epidemic started from September 2016, with 730 cases reported till June 30(th) 2017, in mainland China that caused profound influences on both social development and health of the people. As an emerging infectious disease, information on pathogenic characteristics, transmission patterns and other epidemiological features of H7N9 virus somehow remained unclear. Data from previous studies suggested that the live poultry market (LPM) seemed to have served as main places where H7N9 virus got originated, mutated, spread and thus infected the human beings. Hence, closure of LPMs was suggested a major measure to control and prevent H7N9 epidemics in China. However, the effectiveness of different ways of LPM closures on H7N9 epidemics had been controversial. This study systemically summarized the effects of different ways of LPM closures on H7N epidemics from previous studies, aiming to provide references for developing a better program on H7N9 control and prevention in the country.

自2013年3月我国经历了5次人感染H7N9禽流感大流行,其中2016年9月至2017年6月30日内地报告病例730例。目前尽管对人感染H7N9禽流感的病原学、传播规律、流行特征尚缺乏深入了解,但现有研究提示活禽交易市场可能是病毒来源、变异、传播和感染人类的主要场所,而关闭活禽市场已成为目前防控该疫情的主要手段。但不同形式的活禽交易市场休市对人感染H7N9禽流感流行的影响仍未明确。本文综述了我国不同形式的活禽市场休市对人感染H7N9禽流感流行的影响。.
