在创纪录的飙升中，美国现在平均每天有更多的新冠肺炎病例根据疾病控制和预防中心周三更新的新数据，比疫情任何其他地方都多。

联邦数据显示，美国现在平均每天报告超过27.7万例新病例，打破了去年1月以来每天25万例的纪录。

“这些数字绝对惊人，尤其是考虑到我们已经进入疫情两年了，”波士顿儿童医院流行病学家、美国广播公司新闻撰稿人约翰·布朗斯坦博士说。

在创纪录的平均水平之前，美国连续两天报告了超过43万例新病例，此前测试需求飙升，假期报告数据积压。

过去一个月，美国每日平均病例增加了两倍，仅在过去一周，美国就报告了190多万新病例，平均约有三名美国人检测呈阳性为新冠肺炎分秒必争。

布朗斯坦说:“迄今为止，最容易传播的变种与假日旅行和聚会结合在一起，创造了破纪录的病例数。”omicron变体。“考虑到检测的短缺以及官方统计中没有家庭检测结果，这些数字很可能被严重低估。”

尽管病例总数的大幅上升在很大程度上是由于该国最近的激增，但包括假期周末数据积压和测试需求激增在内的多种因素可能会人为地增加总数。

此外，超过30个州在假期期间没有一致的报告，这也可能严重扭曲数据。

然而，周二，疾控中心主任罗谢尔·瓦伦斯基在接受NPR采访时表示，考虑到目前新冠肺炎检测的短缺，最终，阳性病例的官方数字可能被低估了。

该国最近的激增是广泛的，该国每个州目前都经历了高社区传播。6月，没有一个州报告社区传播率高。

根据联邦数据，住院人数也在增加，尽管只有去年冬天的三分之二。

在全国范围内，目前有超过84，000名美国人因新冠肺炎病住院——在过去7周内增加了40，000名患者。平均而言，每天有9400多名美国人和新冠肺炎一起住进医院，上周增加了近20%。

随着检测需求的增加和医院系统的重新紧张，联邦政府已经部署了快速反应小组来帮助支持国家新冠肺炎应对措施，从疫苗接种到检测，再到临床护理。

超过13，000国民警卫队成员已经被激活在48个州支持国家的新冠肺炎应对措施，包括疫苗接种、检测和临床护理。

周一，安东尼·福奇博士告诉美国广播公司的惠特·约翰逊说很难确切知道考虑到如此多的美国人仍未接种疫苗，该国最近一次激增将在何时达到峰值。

“在好转之前，情况会变得更糟——这是肯定的。我们不指望事情会在几天到一周内好转。这可能需要更长的时间，但这是不可预测的，”福奇说。

此时，8900万美国人仍然完全没有接种疫苗，只有不到三分之一的完全接种疫苗的人得到了加强。

US shatters COVID case records, as experts predict infection rates will continue to grow

Amid a record-breaking surge, the U.S. is nowaveraging more COVID-19 cases per daythan at any other point in the pandemic, according to new data updated on Wednesday from the Centers for Disease Control and Prevention.

Federal data shows the nation is now reporting an average of more than 277,000 new cases a day, shattering the previous record of 250,000 cases per day from last January.

"These numbers are absolutely staggering, especially considering we are two years into the pandemic," said John Brownstein, Ph.D., an epidemiologist at Boston Children's Hospital and an ABC News contributor.

The record average comes after the U.S. reported two consecutive days of more than 430,000 new cases, following soaring demand for tests and a backlog of holiday reporting data.

Over the last month, the U.S. daily case average has tripled, and the nation has reported more than 1.9 million new cases in the last week alone -- an average of about three Americanstesting positivefor COVID-19 every second.

"The combination of the most transmissible variant to date alongside holiday travel and gatherings is a recipe for record-breaking case counts," Brownstein said, referring tothe omicron variant. "These numbers are likely to be a significant undercount given, the shortages in testing and the absence of home test results in official counts."

Although the significantly high case total is due, in large part, to the country's latest surge, a number of factors, including data backlogs from the holiday weekend, and a surge in testing demand, may artificially increase the totals.

In addition, more than 30 states are not reporting consistently over the holiday stretch, which can also significantly skew data.

However, on Tuesday, CDC Director Rochelle Walensky told NPR in an interview that given the shortage in COVID-19 tests right now, ultimately, the official number of positive cases is likely undercounted.

The nation's latest surge is widespread, with every state in the country currently experiencing high community transmission. In June, no states were reporting high community transmission.

Hospitalizations are also on the rise, according to federal data, albeit about two-thirds the levels experienced last winter.

Across the country, more than 84,000 Americans are currently hospitalized with COVID-19 -- up by 40,000 patients in the last seven weeks. On average, more than 9,400 Americans are being admitted to the hospital with COVID-19 every day, up by nearly 20% in the last week.

With increased demand in testing and a renewed strain on the hospital system, the federal government has deployed surge teams to help to support the national COVID-19 response, from vaccinations, to testing, to clinical care.

More than 13,000National Guard members have been activatedin 48 states to support the nation's COVID-19 response, including vaccinations, testing and clinical care.

On Monday, Dr. Anthony Fauci told ABC News' Whit Johnson that itis difficult to know exactlywhen the country's latest surge will peak, given the fact that so many Americans remain unvaccinated.

"It's going to get worse before it gets better -- that's for sure. We don't expect things are going to turn around in a few days to a week. It likely will take much longer than that, but that's unpredictable," Fauci said.

At this time, 89 million Americans remain completely unvaccinated, and less than a third of fully vaccinated people have been boosted.
