“武汉肺炎”的早期警告信号被忽略

更新于2020年1月28日 11:31潘宇:安邦智库研究人员注意到,从2018年开始,中国的流感病发数量就出现不正常的异常上升,幅度令人吃惊。



感冒是对上呼吸道感染的一种非严格称谓,感冒分为两大类,病毒性感冒(如流感病毒、腺病毒、鼻病毒等引起的上呼吸道感染)和细菌性感冒(如细菌性咽扁桃体炎)。其中,病毒性感冒的导致病毒种类很多,包括鼻病毒、副流感病毒(与流感病毒不是同类)、呼吸道合胞病毒、埃可病毒、柯萨奇病毒、冠状病毒、腺病毒等等。注意,一般认为冠状病毒是其中一种,但也有分子生物学的论文和一些科学研究认为,它们并不同相同。不过从认识角度来看,大致在相当程度上可以认为,武汉肺炎实际上就是一种严重的流感。流感一直是困扰全世界的一项季节性传染病。据世界卫生组织报告,流感每年可导致全球5%-10%的成人和20%-30%的儿童发病(约有10亿人),大多数为轻症,重症病例约300万-500万,死亡病例约29万-65万。由于流感病毒容易发生变异,且难以预测,所以每年流行情况都有变化,防控工作具有长期性、复杂性和艰巨性的特点,是全球长期关注的重大公共卫生问题之一。中国为此还成立了专门的流感监测中心和网络,目的就是为了防止流感及病毒的传播。遗憾的是,一些重要的疾病传播信号,显然被忽略了。安邦智库的研究人员注意到,从2018年开始,中国的流感病发数量就开始出现了不正常的异常上升,而且上升的幅度令人吃惊。根据国家疾病预防控制局的数据,从2017年12月开始,中国流感发病人数出现了不正常的增长。即使考虑流感病毒爆发的季节性特点(冬季为主),2017年12月染病人数约在12万例,相比上年同期增幅达到400%。如果以当年12月至下一年3月为主要的流感爆发期评估,2015-2016年度以及2016-2017年度总发病人数均在10万-15万这一区间中。而2017-2018年度,感染人数达到了惊人的60万人左右;到了2018-2019年度则为140万人左右。从数据分析的角度看,病毒导致的疾病从2018年开始表现异常——根据国家卫健委的数据,2019年流行性感冒占据143例,发病数量则是超过60万例。类比往年1月数据,2016和2017年发病2.33和3.01万例,死亡均为6例。作为流感暴发大年,2018年1月报告发病数量约为27.39万例,死亡56例。从这些数据可见,从2018年开始,病毒感冒出现惊人的上升幅度,达到10倍左右;到了2019年,病毒感冒更是大幅上升到相当于正常年景的30倍,这意味着导致人体感染的病毒一定发生了“多层次或者种类”上的突变,而且超过了现有医疗技术条件的可控限度。这种情况实际从2018年就开始出现了,现在回头来看,这种情况非常诡异,需要重新定义和研究。国家卫健委虽然很早就反复发出过警告,但就现在的传染规模和损害来看,显然也低估了可能导致的复杂情况。流行病学是一种科学,其认识结论有一定固有的理论框架,通常情况是可靠的,却无法应对病毒的突变,尤其是尚无法提前明确的预测和预警。因此很遗憾的是,这些数据显示的征兆被忽略,出现武汉肺炎的大爆发。所以结论是清楚的。首先,国家卫健委上实际提早发布过相关警告;其次,国家卫健委和有关专家低估了流感传染的规模、程度和影响。应该说,忽略这种明显的危机信号,这是一个很大、很惨重的教训。在人口众多、资源有限的中国,今后必须加强机制性建设才能真正解决问题。(注:潘宇是安邦智库“武汉肺炎”应急组成员。本文仅代表作者个人观点。责编邮箱bo.liu@ftchinese.com)
