COVID-19 Nasal Swab Test Does Not Cause Risk of Infection

Upon downloading WeChat, users are prompted to register either using their QQ accounts or their cell phone numbers. The application then helps users populate their contact lists using existing entries in their cell phone address books. To communicate, users can upload any photo or video on their device, take new ones, or press a button to save a voice message that is transferred almost instantaneously. Voice messages are played back with short beeps at the end to imitate the feeling of instant connection, similar to a two-way radio.
“很显然,单独一个年度,即使是创记录的年度,不可能告诉我们很多关于气候变化趋势的东西,”德国波茨坦气候影响研究所地球系统分析部门主管斯德范·拉姆斯朵夫(Stefan Rahmstorf)说。“然而,有记录以来的最热年度是2014年、2010年和2005年的这个事实清楚地表明,全球变暖并没有‘在1998年停止’,像一些人喜欢错误地宣称那样。”
同时,大批与比特币相关的创业公司于2014年创建,表明比特币势头强劲。我们没有比特币新创企业的详尽名单,但几乎可以肯定的是,2014年成立的比特币新创企业的数量,高于此前任何年份。融资平台AngelList发给《财富》的数据证实了这一点。2011年,5家比特币初创公司在AngelList上登记。2012年,这个数字增加到13家;2013年跃升至193家;2014年更是暴增至566家。【但并非所有创业公司都会(立即)在AngelList上登记。】此外,正如巴里o希尔伯特在推特上所言,1月8日,比特币日交易总量创下历史新高。

Full Story

To help control the spread of COVID-19, the Centers for Disease Control and Prevention has recommended getting a COVID-19 test for people who show symptoms of the disease, have come into contact with someone known to have the disease, or are in vulnerable groups. 

The most common form of testing for the novel coronavirus involves the use of a nasopharyngeal, or nasal, swab. The swab reaches deep into the back of a person’s nose and mouth to collect cells and fluids from the upper respiratory system, which can then be checked with diagnostic tests for the presence of the novel coronavirus known as SARS-CoV-2.

The testing procedure involves inserting a 6-inch-long swab into the cavity between the nose and mouth for 15 seconds and rotating it several times. The swabbing is repeated on the other side. The swab is then inserted into a container and sent to a lab for testing.

Dr. Shawn Nasseri, an ear, nose and throat surgeon based in Beverly Hills who has conducted many COVID-19 swab tests, told us in an email that the nasal swab “follows the floor of the nose and goes to where the nose meets the throat, or naso-pharynx.”

Asked if the swab test is safe, Nasseri said, “Absolutely. The biggest risk is discomfort. The rare person — 1 in thousands — passes out from being super sensitive or gets a mild nosebleed. It’s estimated that close to 40 million or more swabs have been performed safely in the U.S. alone.”

But in recent weeks, viral posts on Facebook falsely claim that the nasal swab test can cause serious health issues. One post says, “The stick deep into the nose causes damage to the hamato-encephalic barrier and damages endocrine glands. This test creates an entrance to the brain for every infection.”

The hamato-encephalic barrier, also known as the “blood-brain barrier,” protects the brain from toxins that could be present in the blood.

Dr. Yvonne Maldonado, a professor of epidemiology at the Stanford University School of Medicine, told us in an email that the Facebook claim “is not true.”

这位工作人员说道:“她注册时说自己姓韩,也不是像媒体上报道的姓苏。”
Wang Jianlin, the entertainment mogul behind a series of high-profile acquisitions in Hollywood, and internet tycoon Jack Ma retained their spots at the top of the list, with fortunes of $32.1bn and $30.6bn respectively.

Nasseri said that “it is incredibly implausible, if not impossible, to cross the skull base and blood-brain barrier with a swab unless someone uses a rigid metal instrument and is pointing the metal object 90 degrees in the wrong direction.”

Dr. Morgan Katz, an infectious disease expert at Johns Hopkins University, told the Associated Press that the Facebook posts misunderstand what’s happening when the swab test is performed.

尽管可以下载的课程具有较好前景,但在现实世界,得到官方承认的学历仍然基于课堂教学活动。初创公司采取了这样一种态度:如果他们无法以新的服务交付方式在高校的地盘上击败它们,那就应该与之建立合作伙伴关系。其结果是,他们忙着争取考试委员会核准他们的在线课程,使其可以算作学士或硕士学位资格的一部分。

对于其他队伍而言,在球场上拥有良好判断力的德国也是一直非常出色的队伍。意大利也是世界杯上无法忽视的队伍,而拥有罗纳尔多的葡萄牙队将会是一直极具危险性的队伍。拥有众多的大将的比利时队也将成为人们口中津津乐道的黑马队伍。
