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


Quick Take

根据周一发布的年度调查报告,如今实现澳大利亚梦的成本急剧上升,悉尼和墨尔本超过大多数欧美城市,跻身世界最贵城市前五名。
陶博宏表示,这可能过于悲观了。他说:“亚洲的情况往往比我们想象的更快变化。”
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.”

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.
