  2月19日,停泊日本横滨的“钻石公主号”邮轮断绝期满,首批500名新冠病毒核酸测试后果为阳性的搭客下船。停止外地工夫18日23时,“钻石公主号”共确诊542例。在断绝筛查以前,船上统共有3711人,传染比例高达14.6%。外地工夫18日,日本厚生休息相加藤胜信透露表现,“钻石公主”号邮轮一切搭客的新冠病毒取样任务已实现,估计21日,一切检测呈阳性的搭客都将下船。

  据香港媒体报导,停止2月18日,确诊542例中包含53名香港住民。香港特区当局2月19日派出包机,将把病毒检测后果为阳性、且无发热等病症的香港住民接回。

  别的,据日本当局透露表现,外地工夫17日早上,有328名美国人下船,并在7时从东京羽田机场入境。美国国务院称,在这局部职员中,新查明14人传染新冠肺炎,但答应他们搭乘包机,并在机舱内采纳了出格断绝办法。

  别的,加拿大、意大利、以色列、澳大利亚等各方也正预备经过包机将滞留搭客接回外国或地域。

  整艘船14.6%的传染率,钻石公主号为什么成重灾区?

  一些专家疑心,“钻石公主”号邮轮断绝办法不太严厉。

  伦敦大学国王学院疾病专家纳塔莉·麦克德莫特揣度,船上的“断绝办法分明没起感化,这艘船如今已成为感染源”。假如断绝办法妥当,“没有来由不起感化”。

  她通知美联社:“咱们需求理解船上若何履行断绝办法、船上的氛围过滤零碎若何运行、各舱室若何相连、以及渣滓若何处置。”

  虽然日本当局再三反驳邮轮断绝办法无效,但仍有人以为当局此举分歧格。此前3名日本卫生官员帮忙邮轮停止断绝核对,后果也被传染。这标明邮轮外部能够存在办理涣散的迹象。

  Ventilation inside each cabin is regulated by central air-conditioning。 There are two types of circulation functions of air conditioners。 One is the air refresh system, in which exchange between interior and exterior air is achieved in order to adjust the temperature inside the cabins。 The other is the air re-circulation system, through which temperature adjustment through the air re-circulation system。 

  Although the first system provides fresh air for the passengers, an option that could create much healthier conditions, it does consume much more energies。 The air re-circulation system, on the other hand, creates a scenario in which the air flowing in from the air conditioning is the air flowing through many passenger cabins and therefore passengers, although confined to their chambers, may be exposed to a turbid flow of air。 It is likely that the Diamond Princess failed to turn on the air refresh system in time, which resulted in the spread of the virus。

  But a number of experts have doubted this assertion。 They said it is likely that infections happened mostly before the imposition of the quarantine。 

  正如专家指出,任务职员也能够是病毒深度浸透的缘由之一,由于他们打仗到少量能够传染病毒的搭客,一旦任务职员传染了病毒,他们很简单成为病毒的传达者。

  天下卫生构造前西安定洋地域主任尾身茂指出,船上任务职员没有像搭客同样承受断绝,他们“同吃同住,这是断绝开端后一些人传染病毒的缘由”。

  就“钻石公主”号上病毒传达速率快,天下卫生构造卫生告急名目主管迈克尔·瑞安表明,“偶然候疾病在一些情况中便是能更疾速传达,比方邮轮。”

  他透露表现,置信日本当局以及接回外国百姓的其余国度当局“有才能以得当体式格局持续跟进这些人”的安康情况。

  尾身茂说,病毒传达晚期,断绝是无效按捺传达的办法。他倡议,跟着病毒逐渐进入日本社区,日本当局该当把重点从边疆管控转移至禁止病毒在社区内传达。

  As experts endeavor to find an alternative explanation to account for the failure of virus prevention, they turn the focus onto quarantine measures。 

  While the Japanese government has repeatedly defended the effectiveness of the quarantine, some suggest it may have been less than rigorous。 Three Japanese health officials who helped conduct the quarantine checks on the ship were also infected, indicating a possible sign of lax protocols。 

  “There are sometimes environments in which disease can spread in a more efficient way,” said Dr。 Michael Ryan, executive director of the World Health Organization‘s health emergency program。 Ryan said cruise ships, in particular, were known to occasionally accelerate spread。
