官员告诉美国广播公司新闻，疾病控制和预防中心将于周五发布新的备受期待的指导，在美国许多地区放宽室内掩蔽建议。

新的指导方针预计将概述该国应如何进入疫情的下一阶段，重点从社区的日常传播转移到病毒更严重的影响，如住院和卫生保健压力。

CDC主任Rochelle Walensky公开表示，该机构正在更新指南。

“展望未来，我们的方法将建议在严重疾病高发的社区加强预防工作，并将重点放在保护我们的医疗保健系统免于不堪重负，”她周四晚些时候在推特上说。

新的指南旨在帮助各州和县决定在地方一级应该用什么指标来指导决策。奥米克隆在全国范围内已经基本消退，这让许多美国人渴望在疫情潜在的平静期保持一些正常。

在州长和州官员数周的压力下，更新的指南出台了，他们要求在国家层面制定一个明确的路线图。

尽管大多数州在疾病预防控制中心的指导意见准备就绪之前就已经宣布将取消口罩要求，但新信息仍然可以帮助当地领导人和公共卫生官员，即使在同一个州，他们也面临着截然不同的疫情版本。

如果出现新的变种，它也将为各州和县重新实施指导方针提供指导，专家警告这是一种可能性。

指南中最大的变化将是关注病毒最严重的影响，而不仅仅是有多少人感染了病毒。预计疾病预防控制中心将敦促官员们根据他们的医疗保健系统的运作情况做出决定——强调医院容量和病人的病情等因素——而不是某一天社区有多少病例。

然而，瓦伦斯基警告说，疫情不会有一个“确定的日期”结束。

她在周二的播客采访中说，“我认为我们会小心翼翼地走出困境，有一天，我们会慢慢地意识到，现在回想起来，我们已经不再是这样了，或者至少不会像过去两年那样了。”

CDC to release guidance Friday that would ease mask restrictions for many Americans

The Centers for Disease Control and Prevention will release new and highly anticipated guidance on Friday that eases indoor masking recommendations in many parts of the U.S., officials told ABC News.

The new guidance is expected to outline how the country should move into thenext phase of the pandemic, with a shifted focus from daily spread in a community to the more severe impacts of the virus, like hospitalizations and health care strain.

CDC Director Rochelle Walensky has said publicly the agency was updating the guidance.

“Moving forward, our approach will advise enhanced prevention efforts in communities with a high volume of severe illness and will also focus on protecting our healthcare systems from being overwhelmed,” she tweeted late Thursday.

The new guidance will be intended to help states and counties decide what metrics should guide that decision at a local level. Omicron, which has substantially subsided across the country, left many Americans feeling eager to retain some normalcy during a potential lull in the pandemic.

The updated guidance comes after weeks of pressure from governors and state officials who asked for a clear roadmap at the national level.

Though a majority of states went ahead and announced that they will drop mask mandates before the CDC’s guidance was ready, the new information could still aid local leaders and public health officials who are facing vastly different versions of the pandemic even within the same state.

And it will also give states and counties a guide to re-implement guidelines if a new variant pops up, which experts warn is a possibility.

The biggest shift in the guidance will be the focus on the most severe effects of the virus instead of just how many people are catching it. The CDC is expected to urge officials to make decisions based on how well their healthcare systems are working — emphasizing factors like hospital capacity and how sick people are getting — instead of how many cases there are in the community on a given day.

Walensky has cautioned, though, that there won’t be a “date certain” that ends the pandemic.

“I think we're gonna tiptoe out of this and that we will very gradually, one day, realize in retrospect, we're no longer in this anymore, or at least in it the way we have been for the last two years,” she said in a podcast interview on Tuesday.
