根据网友bustout的帖子，我将川普行政当局到3月18日为止应对新冠病毒的主要举措列了一个表，供大家参考。

列这个表的目的，一是帮助我们了解川普当局在应对新冠病毒方面，迄今为止到底做了什么；二是展示一个有鲜明美国特色的应对重大公共卫生危机的战略策略全景；三是有利于我们在美生活、工作、学习的华人华侨及留学生了解相关的政策、保障我们自己的合法权益。

有网友说，川普政府在3月13日宣布全国紧急状态之前基本上没做什么，这是非常不公平的。举个例子：思芦网友在“美国为什么不用世卫组织的试剂？”（https://bbs.wenxuecity.com/currentevent/2057953.html）一文中指出， 美国在1月份就已开发出自己的高灵敏度、高准确度的试剂盒，CDC在1月18日至2月23日期间即已检测了1千多人的2620个样本。而这里的表格，也显示出在3月13日前已经出台了诸多重要的决策和举措。

美国是一个民主社会，主流媒体舆论以监督批评政府为天职，社会对政府表达不满意，是自然而然和正常的。为应对新冠病毒，川普一方面采取了许多切实的行动，但他是一个天生的大嘴巴，他同时又使用了不太适当的言辞表达以期望降低公众的恐慌情绪。但是，美国股市的狂跌，显示出他的安抚暂时还没有起到作用。接下来，人们要看美国政府现在这一套“精准检测、重点治疗、家庭隔离、social distancing、保障生活、尽量维持社会生产和工作节奏”的组合措施能否有效抑制病毒的扩散、会在多大程度对美国的经济造成影响。
