U.S. COVID-19 Hospitalizations Increase for 6th Straight Week_我的网站
一 |
Coronavirus hospitalizations in the U.S. are increasing with no sign of slowing.
The week ending Aug. 19 saw more than 15,000 new COVID-19 hospital admissions, according to the latest data from the Centers for Disease Control and Prevention. It’s nearly a 19% increase over the previous week and the sixth straight week of growing numbers.
The summer increase remains small compared to previous coronavirus waves in the U.S. Still, it is the first time since winter that the country has experienced growing COVID-19 cases and hospitalizations, and new coronavirus variants have caught the attention of officials.
EG.5, or “eris,” is now the dominant strain circulating in the U.S. It was responsible for more than 20% of new infections in recent weeks, according to CDC data.
The World Health Organization has designated EG.5 a “variant of interest” after it displayed a steady increase globally.
The organization assessed EG.5’s public health risk as “low at the global level,” which is the same designation as the so-called “arcturus” strain.
However, WHO warned that “due to its growth advantage and immune escape characteristics, EG.5 may cause a rise in case incidence and become dominant in some countries or even globally.”
Another new strain, BA.2.86, has been documented in the U.S. Details on the highly mutated strain are scarce, but researchers are watching it closely.
The CDC said in a risk assessment of BA.2.86 that it is likely not responsible for the current rise in COVID-19 hospitalizations and that it is too soon to know the new strain’s transmissibility or severity.

二 | 研究人员最近在《 Journal of Fish Biology》上发表了一份关于迄今为止发现的最大鱼类的报告。他们发现的生物总重量为6049磅，高约12英尺，长约11英尺，是迄今为止捕获的最大的骨鱼。该研究的第一作者告诉表示，这是一个“雄伟的标本”，如果能看到它活着那么将是不可思议的。
三 | 这条新发现的太阳鱼比以前的最大鱼纪录保持者约重1000磅，后者的重量略高于5000磅，是1996年在日本千叶海岸捕获的。研究人员不确定是什么杀死了这条巨大的鱼，然而在它的头骨上发现了一个凹陷以及凹陷处有红色油漆的痕迹--可能是跟船只发生碰撞造成。不幸的是，确切的死因还不清楚。不过清楚的是，这个有史以来最大鱼类的新纪录保持者只是我们最近在海洋中的许多发现之一。此前，研究人员在海底深处发现了一种由蓝色粘液组成的生物。在此之前，研究人员首次捕捉到了一种罕见的水母的镜头。而像这种巨型标本的太阳鱼对人类来说并不完全陌生。事实上，它们可以在世界各地的水族馆中找到。
四 | 如果你好奇为什么太阳鱼会叫这个名字，这跟它的形状没有关系。相反，它之所以被命名是因为它在寒冷的深海中游泳后喜欢晒太阳。
