东莞: 53名密切接触者检测均为阴性
南方日报讯 （记者/骆骁骅）省疾控中心首席专家、传染病预防控制所所长何剑峰昨日在接受南方日报记者采访时表示，东莞新增H7N9确诊病例的53名密切接触者送检样本均为阴性。
何剑峰透露，与前日相比，确诊病例的病情更加危重。其原因除了与“发病和治疗的相隔时间太长”以外，还与患者是成年人，自身机体免疫系统反应激烈有关，“有些儿童病例会是轻症，因为儿童体内的活性因子比较少。”
虽然患者发病5天前曾在一家农家乐餐厅进食鸡只，但何剑峰表示，目前只是怀疑患者在该餐厅感染，传播途径仍然很不明确，“禽类接触史很难回溯，患者可能经过了禽类市场，也有可能自己也忘记了接触过禽类。”
广州：难以杜绝风险来源 仍存散发风险
广州市疾控中心副主任杨智聪昨日向记者表示，广州自今年4月3日以来已经建立起对肉菜、禽鸟市场，南沙湿地、海珠湖、白云山等环境样本的检测技术体系，并对相关从业人员、医院不明流感样病例保持持续监测。近期的监测数据显示，广州没有检出H7N9阳性的人及环境样本。
“没检测出不等于广州就真的没有H7N9，事实上广州很难杜绝风险来源，现在正值冬季候鸟南迁的季节，广州仍然存在散发病例的风险。”杨智聪表示，一旦广东或广州出现情况异常，市疾控将相应调整疾控对策。
