中国东部省份江苏省已确诊消失四例H7N9禽流感病例，针对此罕见致命病毒，中国已在全国范围内开展监测行动。

江苏省卫生局通报称，这四名病患分别生活在不同城市，大约在3月20日前后消失发热、咳嗽等病症，目前病情危重。在周二下午他们被确诊感染H7N9禽流感。

两名上海男性上周日死于H7N9禽流感，年龄分别为27岁、87岁，一名安徽女性状况危险，目前全国共确诊7例H7N9病例。

与江苏省四名病例亲密接触过的上百人尚未发觉有发热或呼吸道病症。

中国疾控中心卫生应急中心主任冯子健表示，由于感染缘由尚不行知，相关机构已在全国范围内开展肺炎患者跟踪打算，监控H7N9禽流感病毒。

这一打算得到了包括医院在内的公共卫生组织监测系统的支持，目的在于准时发觉新病例。

冯子健表示，为了确定病毒根源，将调查现有病例的身份背景和生活环境。他还补充说道，“病毒来源于猪还是其他动物尚不行知。”

江苏省指定16家三级甲级医院作为该省H7N9禽流感确诊病例定点收治医院，同时，组织各级医院加强对肺炎病例的监测。

其他城市包括上海、北京等，均制定应急方案来应对这一未知禽流感的大范围爆发。

上海市政府周二启动流感流行三级应急预案，拉响禽流感黄色预警。
