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


Quick Take

无人驾驶汽车是当下炒作得最火的行业,这类汽车的倡导者已成为冗词赘语的世界级领军人物。埃隆?马斯克(Elon Musk)自称“要在一个安全系数超出人工驾驶数量级倍数的一体化平台上专注于全自动驾驶的实现”。(就是说特斯拉肯定能防止车祸的发生)。
Once the U.S. economic recovery started in 2009, other parts of the world started to struggle in their own ways.

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.”

如果一部情景喜剧播出10年堪称流行,那么播出20年后依旧令无数人挂怀的电视剧则是经典。《老友记》1994年在美国首播,讲述了六个生活在纽约的青年男女的故事。现在,该剧已经是最著名的情景喜剧之一,在全球超过100多个国家和地区播出。

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.

但是,当今年12月WTO成员国聚集在布宜诺斯艾利斯召开两年一度的部长级会议时,我们将一尝世界新秩序的味道。一如既往的是,目前尚不清楚WTO此次能否产生一些实质性内容。但真正的考验在于,WTO有史以来第一次不由美国牵头讨论。中国或欧盟会取而代之吗?印度会像过去一样一心阻挠任何协议吗?
"Even though these two researchers worked independently of one another, the combination of Shapley's basic theory and Roth's empirical investigations, experiments and practical design has generated a flourishing field of research and improved the performance of many markets," the academy said.
