2013年3月31日至5月31日，共有132例人类感染H7N9禽流感病毒，其中39例导致中国死亡，引发全球对公共卫生的担忧。幸运的是，自5月8日以来，中国没有新病例报告，这似乎使其步入稳定阶段，由上海、江苏、浙江、安徽、江西、山东、中国的河南启动的事件应急响应目前已终止。然而，7月20日和8月10日，河北和广东两省报告了两例新病例，这两个省份在2013年春季期间没有病例报告。出现的两起新病例敲响了警钟，因此，持续的公共卫生应对措施不能放松警惕。在以往研究的基础上，我们发现，活禽购买习惯、家禽处理方式和生活条件增加了中国暴露于H7N9病毒污染环境的风险。鉴于中国难以改变购买活禽的习惯，难以彻底取缔或关闭活禽市场，我们建议加强对家禽市场的监管是抗击中国H7N9病毒感染的更可行和更有效的策略。此外，由于家禽处理和生活条件的原因，农村居民与农村居民居住的家禽也存在频繁和不可避免的接触，因此也需要加强对散养家禽，特别是农村地区的环境卫生监管。
From March 31 to May 31, 2013, 132 cases of humans were infected with the H7N9 avian influenza virus, 39 of which resulted in death in China, which sparked global concerns about public health. Fortunately, no new case was reported in China since May 8, which seems like to make it step into a stable stage, and the emergency response to the event launched by Shanghai, Jiangsu, Zhejiang, Anhui, Jiangxi, Shandong, and Hu'nan of China have been terminated currently. However, on July 20 and August 10, two new cases were reported from two provinces - Hebei and Guangdong - where no case was reported during the period of spring of 2013. The emerged two new cases rung an alarm bell, thus, the continued public health response cannot let down its guard. Based on our before studies, we found that live poultry purchasing habits, poultry handling, and living conditions increase the risk of exposure to H7N9 virus contaminated environments in China. Due to the difficulty in changing live poultry purchasing habits and in thoroughly removing or closing live poultry markets in China, we suggest that enhanced regulation of poultry markets would be a more feasible and effective strategy to fight against H7N9 virus infection in China. Moreover, in view of the fact that frequent and inevitable contact between rural residents and poultry where rural residents lived also exists due to poultry handling and living conditions, the enhanced regulations on environmental health are also needed for free-range poultry, especially in rural areas.
