美国新冠疫情发展仍不明朗 唯一安慰是新冠疫苗研制

  新冠疫情发展并不明朗,但唯一让人安慰的事情就是新冠疫苗的研制,下面一起和天道小编看看约翰霍普金斯大学卫生专家的建议。

  新冠疫情在美国进入了最严重的阶段,尽管新冠疫苗前景一片光明

  在冠状病毒激增的情况下,约翰霍普金斯大学的公共卫生专家建议在未来几个月保持低调以挽救生命

  约翰霍普金斯大学彭博公共卫生学院(Johns Hopkins Bloomberg School of Public Health)的专家说,尽管疫苗有望最终摆脱COVID-19危机,但美国进入冬季时面临着迄今为止最令人担忧的趋势。

  流行病学教授Amber D'Souza在周四下午布隆伯格学院举办的一场讨论中说:“这是红色代码。”“无论你看哪种数据和指标,这都是疫情最严重的部分。”

  随着美国每日新增病例不断刷新纪录,COVID-19已成为美国的头号死亡原因,一些医院面临着超出其能力范围的病人激增。流行病学副教授大卫道迪(David Dowdy)说,在未来几周,“情况将变得更糟,而不是更好。”

  但专家强调,希望并没有消失。“我们可以做一些事情,”德索萨说。“现在还不晚。”

  “这是这样的时刻……我们应该团结起来,聪明地做这件事,在这个冬天拯救生命。”因为如果我们坚持下去,就会产生巨大的影响。”

  欧洲彭博公共卫生学院(Bloomberg School of Public health)提供了一个令人鼓舞的例子。他们有效地遏制了最近COVID-19的激增,这与美国目前正在经历的疫情相似。约翰·霍普金斯卫生安全中心(Johns Hopkins Center for Health Security)的高级学者凯特琳·里弗斯(Caitlin Rivers)说,在那里,有针对性的关闭和限制已经产生了影响。

  美国的一些地区正在尝试类似的方法。里弗斯说:“在这场大流行的过程中,我们必须做出非常艰难的权衡和决定。”他建议一些地区应该考虑以暂时关闭餐馆和酒吧为代价,让学校继续开放。“我认为,想方设法让学校安全运行应该是我们国家的首要任务。”

  布隆伯格学院负责公共卫生实践和社区参与的副院长Joshua Sharfstein提到了最近两家主要的COVID-19疫苗研发商的好消息。在第三阶段的试验中,辉瑞和Moderna在准备向FDA申请紧急使用许可时,在初步分析中都报告了90%以上的疗效。他说,这两家公司已经开始提前生产疫苗,因此年底前可能会有数百万剂疫苗可用。

  不过,Sharfstein说,可能要到2021年春季或夏季,才会有足够多的人口接种疫苗来抑制病毒。“这就是我们试图建立的桥梁——从现在到我们有大量安全有效的疫苗来产生群体免疫之间的桥梁。”

  道迪说,这个冬天可能是流感大流行的最后一次大规模爆发,但关键是在这段时间内阻止传播。他说:“未来两到三个月可能会发生很多事情。”“我们现在需要尽我们所能来限制这种损害。”

  D'Souza承认随着大流行病无情地拖延,“COVID疲劳”的现实。“作为一个国家,我们已经在经济、社会和健康方面付出了巨大代价。还有希望。这是关于这些疫苗潜力的好消息,”她说。“这是这样的时刻……我们应该团结起来,聪明地做这件事,在这个冬天拯救生命。”因为如果我们坚持下去,就会产生巨大的影响。”

  COVID-19 pandemic enters its most serious phase in U.S., even as vaccine prospects brighten

  Amid record surges of the coronavirus, Johns Hopkins public health experts advise hunkering down to save lives in the months ahead

  Though vaccines promise an eventual path out of the COVID-19 crisis, the U.S. enters winter facing the most alarming trends yet, according to experts from the Johns Hopkins Bloomberg School of Public Health.

  "This is code red," said epidemiology professor Amber D'Souza during a discussion hosted by the Bloomberg School on Thursday afternoon. "No matter which of the data and the metrics you look at it, this is the most serious part of the epidemic."

  As the U.S. continues breaking records for new daily cases of the disease, COVID-19 has become the nation's leading cause of death, and some hospitals are facing patient surges beyond their capacities. Over the next few weeks, "things are going to get worse rather than better," said David Dowdy, associate professor of epidemiology.

  But hope is not lost, the experts emphasized. "There are things we can do," D'Souza said. "It's not too late now."

  "THIS IS SUCH A MOMENT … FOR US TO RALLY AND DO THIS SMARTLY AND SAVE LIVES OVER THE WINTER. BECAUSE IF WE HOLD OUT, IT CAN MAKE A TREMENDOUS DIFFERENCE."

  Bloomberg School of Public HealthEurope offers an encouraging example. They effectively contained a recent COVID-19 spike that shared similarities to the one the U.S. is currently experiencing. There, targeted closures and restrictions have made an impact, said Caitlin Rivers, a senior scholar at the Johns Hopkins Center for Health Security.

  Some areas of the U.S. are now trying similar approaches. "We have to make really difficult tradeoffs and decisions in the course of this pandemic," Rivers said, suggesting that some regions should consider keeping schools open at the expense of temporarily closing restaurants and bars. "Finding ways to make schools safe to operate, I think, should be our absolute top national priority."

  Joshua Sharfstein, vice dean of public health practice and community engagement at the Bloomberg School, pointed to promising recent news from two major COVID-19 vaccine developers. In phase 3 trials, both Pfizer and Moderna have reported efficacy above 90% in preliminary analyses as they prepare to file for FDA emergency use authorizations. Both companies have already begun manufacturing the vaccine in advance, he said, so millions of doses may be available before the year's end.

  It could be well into spring or summer 2021, though, before enough of the population is vaccinated to tamp down the virus, Sharfstein said. "That is the bridge we're trying to build—between now and that time when we have a lot of doses of safe and effective vaccines to use, to generate the herd immunity."

  This winter could mark the pandemic's final big surge, Dowdy said, but the key is to stop the spread during that time. "A lot can happen in the next two to three months," he said. "We need to do what we can today to limit that damage."

  D'Souza acknowledged the reality of "COVID fatigue" as the pandemic drags on relentlessly. "We've already paid such a toll economically, socially, and in health as a country. And there's hope. There is great news about the potential of these vaccines," she said. "This is such a moment … for us to rally and do this smartly and save lives over the winter. Because if we hold out, it can make a tremendous difference."
