据约翰斯·霍普金斯大学数据显示，截至北京时间4月20日5时38分，美国新冠肺炎确诊病例升至755533例，死亡病例达40461例。 另据美国国防部数据，截至17日，有2986名现役军人确诊。至此，分布在美国41个州的超过150个军事基地以及4艘航母上均已出现新冠肺炎确诊病例。 In the U.S., over 40,000 deaths have been reported and total confirmed cases have surpassed 755,000, meaning the U.S. has the largest number of both coronavirus fatalities and infections in the world. 美国副总统彭斯19日表示，确保安全情况下将会继续鼓励各州陆续恢复民众正常生活。他强调，在开放了各州所有检测实验室后，有信心让各州都具备条件尽快解除限制令。 然而，决定美国重启计划关键的疫情检测却出现了不少问题。 近两日来，接连爆出检测实验室污染导致试剂失灵、市面在售多个核酸试剂盒不合规等事件，使得全美新冠病毒检测工作不得不往后延迟。 Washington state has recalled 12,000 test kits of the novel coronavirus pneumonia (COVID-19) due to possible contamination, the state's Department of Health announced (DOH) last Sunday. The department was alerted by the University of Washington Medicine (UW Medicine) on April 17 to stop using a recently-procured batch of COVID-19 specimen collection kits which the university believed may have a "quality control issue." DOH explained in a news release that some of the vials of viral transport media (VTM) – the fluid that preserves a specimen during transport – were an unusual color, which led UW Medicine to reach out to the health department to investigate potential contamination. 据《华盛顿邮报》报道，超过90款新冠病毒抗体试剂在没有监管情况下已经流向市场，这与美国食药管理局放弃了试剂审核有关。目前在美经过FDA审核的新冠病毒抗体检测试剂仅有4种，这引发了民众对病毒检测效果的广泛担忧。 而近日美国哈佛大学附属麻省总医院进行的一项街头抽样检测的结果更是“令人警醒”。在200名随机抽取血样接受检测的参与者中，就有64人呈阳性，确诊比例高达30%。 美国防疫的挑战还不仅如此。就在疫情接连升级，确诊病例破75万大关的关键时期，美国总统特朗普却有自己的想法。 从17日不顾警告，坚持要“重启美国”之后，特朗普已在多个公开场合表明自己想要复苏经济的急迫性，甚至为了证明美国防疫措施“取得优异成效”，他将各国死亡人数与美国做比较，以此强调美国新冠病毒死亡率远低于欧洲各国。 特朗普表示，种种持续向好的迹象表明，美国新冠肺炎疫情已经越过高峰，“我觉得美国跟德国一样好，甚至比他们更好”。 尽管纽约州长科莫对总统的决策率先提出质疑，但重启计划仍然在各方争议声中悄然进行。 Governor Andrew Cuomo announced the figure in his daily briefing, noting that there was "little room for error" despite a slowing down of the outbreak. He also noted that the continued slowing down of infections was key to the plans to reopen the economy. President Donald Trump earlier this week reiterated his call to have the country reopen as early as May, saying states had adequate testing to warrant a reopening. Some governors have however disputed this claim. 4月17日，佛罗里达州的杰克逊维尔海滩首先响应总统号召，宣布重新向公众开放。尽管开放细则规定了游客需要保持6英尺的“安全距离”，但海滩上仍然摩肩接踵，自觉佩戴口罩的人更是寥寥。 加州圣克鲁斯也紧随其后，宣布将冲浪解禁。 这种短暂的自由似乎让人忘记了病毒依旧在肆虐，形势仍然很严峻。 然而实际上，在过去14天内，佛罗里达州新冠病毒确诊患者的人数在持续上升，在疫情尚未得到控制的情况下，重新开放海滩直接导致当日确诊人数达到最高值——1421人。 Crowds swarmed Jacksonville Beach shortly after Florida Governor Ron DeSantis on Friday announced the reopening of some beaches and parks – if it can be done safely while observing social distancing guidelines. Jacksonville Mayor Lenny Curry said that reopened beaches could be used only for walking, biking, hiking, fishing, running, swimming, taking care of pets and surfing during restricted hours. USA Today said people rushed to the beach "faster than a flock of seagulls chasing a French fry." The U.S. state of Florida recorded its highest daily death toll from the coronavirus on April 14, and has a total of 740 fatalities so far. 惊人的增长数据似乎并没有让美国民众充分认识到疫情的严重性并因此提高警惕。由于各州长期各自为政，缺乏美国联邦政府的协调统筹，疫情的爆发使得双方矛盾日渐凸显，导致全美上下无法在疫情认识及处理方式上达到统一。 被要求需要居家隔离的州民众产生了不满情绪。4月19日，全美多地爆发游行示威，数千人走上街头，要求解除限制措施，并指责政府侵犯个人自由。新罕布什尔州甚至出现民众持枪示威的情形，要求尽快复工。 愈演愈烈的示威活动因为特朗普的一番“推波助澜”的操作迅速达到高峰。2020年4月17日，特朗普连发三条推文：“解放明尼苏达”、“解放密歇根”、“解放弗吉尼亚”，鼓动人们反抗这些地区现有的封城措施和居家令。 Hundreds of protesters gathered outside the Minnesota governor's mansion on Friday to defy stay-at-home measures, hours after Trump tweeted "LIBERATE MINNESOTA." In a series of tweets on Friday, Trump urged "liberating" Virginia, Minnesota, throwing his support behind protesters opposing restrictive measures imposed to slow the spread of the COVID-19. 这一行为遭到多家媒体撰文猛批，指责特朗普鼓吹暴动是在“玩火”，不应该把发表推文看作政治玩笑。美国有线电视新闻网（CNN）更指出，特朗普发布重启经济的指南，目前没有一个州符合条件。 覆巢之下，安有完卵。 如今美国确诊病例数仍在急速上升，形势尚未有缓和的迹象，远没有到可以放松警惕的时候，此时制造混乱和动荡只会造成更加无法挽回的后果。 疫情不是政治博弈的手段，当前只有搁置各自利益主张和政治分歧，齐心战疫，才能战胜病毒这一全人类共同的敌人。
