美国最终敲定交易,到7月底为所有合格的美国人提供足够的疫苗 strong>

拜登总统周四宣布,他的政府已经敲定了从辉瑞/ BioNTech和Moderna购买另外2亿剂疫苗的交易。预计这些剂量将7月底上市,并将使美国的总剂量达到6亿剂。预计将有大约2.6亿美国人被认为有资格使用冠状病毒疫苗,这意味着该国将有足够的剂量为所有这些人充分接种疫苗。拜登任职的第100天,美国政府也正为1.5亿美国人接种疫苗。

世界范围内,采购疫苗仍然很困难。包括中国,印度和阿拉伯联合酋长国内的一些国家正向其他国家开枪,以讨好或加强地缘政治关系。新的研究表明,骗子的疫苗销售热潮正Facebook团体和Telegram聊天中蔓延。

随着新的变体继续美国各地传播,CDC完善了口罩指南 strong>

本周美国的新病例,住院和死亡人数都下降了,但一些专家担心,随着更多可传播的变种的流行,这种趋势可能会逆转。一项新的研究表明,最早英国发现的B.1.1.7突变可能下个月成为美国的主要毒株。周四,伊利诺伊州和北卡罗来纳州成为最新报告其第一例B.1.351病例的州,这是南非首次发现的变种。

更好地防御这些更具传染性的变型的关键方法是确保您的口罩合适,并且可能翻倍。本周,疾病控制中心发布了戴口罩的新指南,此前实验室测试表明,如果两个人都正确佩戴,戴两个口罩可以将传播的可能性降低95%。为此,首先要使用一次性医用口罩,然后顶部盖上一块布口罩。健康至上:如果您呼气时感到热气逸出,则需要进行调整。

随着某些地区开始重新开放,疾病预防控制中心会为学校准备新的指南 strong>

美国疾病预防控制中心(CDC)今天发布新指南,要求学校亲自亲自重新开放。拜登总统曾表示,重开学校是重中之重,疾病预防控制中心主任罗谢尔·瓦伦斯基上周表示,为教师接种疫苗并不一定是重开学校的前提。到目前为止,关于重新开设学校的决定是零星的,各个地区甚至学校都自行决定课程。某些情况下,情况急剧恶化:上周,旧金山起诉自己的学区和董事会,称尽管公共卫生指导认为安全,他们仍未制定有意义的计划重新开放。

该国的其他地方,各区采取了关键步骤以重新开放本周。纽约市宣布,选择亲自学习的初中生将从2月25日开始返回教室。经过数周的紧张谈判,芝加哥与教师工会达成了一项协议。周四,该市的学前班和特殊教育学生恢复了就读课程,预计中小学将未来几周内陆续上课。

梅森罐子,扫帚和早期的互联网有什么共同点?超出您的想象。

当早产儿与父母进行皮肤接触并被养育人所包围时,早产儿表现最佳。但是大流行期间,隔离是关键。这造成了一个压力巨大的悖论:“保护NICU免受病毒感染的相同措施也可能降低其效力。”

冬季的后半段似乎不是购买寒冷天气装备的最佳时机,但是如果您这样做,就有足够的机会节省大笔费用。

America makes deals for more vaccines, the CDC refines mask guidance, and school districts begin reopening. Here’s what you should know:

The US finalizes deals to secure enough vaccines for all eligible Americans by the end of July

On Thursday, President Biden announced that his administration has finalized deals to purchase 200 million more vaccine doses from Pfizer/BioNTech and Moderna. These doses are expected to be available by the end of July and will bring the US total to 600 million doses. Around 260 million Americans are expected to be considered eligible for a coronavirus vaccine, which means the country will have enough doses to fully vaccinate all of them. The administration is also well on its way to vaccinating 150 million Americans by the 100th day of Biden’s presidency.

Around the world, procuring vaccines continues to be difficult. Some countries—including China, India, and the United Arab Emirates—are sending shots to other nations to curry favor or bolster geopolitical relations. And new research has shown that scammy vaccine sales pitches are spreading in Facebook groups and Telegram chats.

The CDC refines its mask guidance as new variants continue to spread across the US

The numbers of new cases, hospitalizations, and deaths in the US all dropped this week, but some experts are concerned that this trend may reverse as more transmissible variants gain traction. A new study suggests that the B.1.1.7 mutation, which was first found in Britain, could be the dominant strain in the US by next month. On Thursday, Illinois and North Carolina became the latest states to report their first cases of B.1.351, the variant first identified in South Africa.

A key way to better protect against these more contagious variants is to make sure your mask fits well, and potentially to double up. This week, the Centers for Disease Control released new guidance on mask-wearing after lab tests showed that wearing two masks can reduce the likelihood of transmission by up to 95 percent if both people are wearing them correctly. To do this, start with a disposable medical mask and layer a cloth mask on top. Fit is paramount: If you feel hot air escaping when you breathe out, you’ll want to adjust.

The CDC prepares new guidance for schools as some districts begin reopening

The CDC is releasing new guidance today for schools to safely reopen in person. President Biden has said that reopening schools is a top priority, and CDC director Rochelle Walensky commented last week that vaccinating teachers is not necessarily a prerequisite for reopening. Up to this point, decisions about reopening schools have been piecemeal, with individual districts and even schools left to chart the course for themselves. In some cases, the situation has escalated dramatically: Last week, San Francisco sued its own school district and board, saying they haven’t made meaningful plans to reopen despite public health guidance that it’s safe.

Elsewhere in the country, districts took key steps toward reopening this week. New York City announced that middle schoolers who opted to learn in person will be allowed to return to classrooms starting February 25. And after weeks of tense negotiations, Chicago reached a deal with its teachers union. On Thursday, the city’s pre-K and special education students resumed in-person classes, with elementary and middle schools expected to follow in the coming weeks.

What do mason jars, shrooms, and the early internet have in common? More than you might think.

Preterm infants do best when they’re in skin-to-skin contact with their parents and surrounded by nurturing people. But during the pandemic, isolation is key. This creates a stressful paradox: “The same measures that protect the NICU from the virus also risk reducing its efficacy.”

The second half of winter may not seem like the best time to buy cold-weather gear, but if you do, there are ample opportunities to save big.
