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


Quick Take

上世纪70年代,考林斯出生在落后的、种族隔离时期的南非。她的童年经历让她更关注通过民间的努力改善贫困女性的生活。创办Wonderbag的灵感源自她观察祖母借助垫子做饭的经历。Wonderbag使用保暖技术在8至12个小时内烹饪食物,无需额外增加燃料。考林斯亲眼见证了非洲女性使用Wonderbag所带来的好处——它减少了她们收集柴火的时间。每卖出一个Wonderbag,这家公司就会向非洲的家庭捐赠一个这样的袋子。过去四年,Wonderbag已经走进600,000个非洲家庭。考林斯还通过亚马逊(Amazon)在美国推出了Wonderbag,并希望到2014年的时候能够通过其他零售商出售自己的产品。

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.

会。在2018年美联储可能多次加息的情况下,新兴市场中的交易可能会波动起伏。有时可能感觉有点像2013年“削减恐慌”(taper tantrum)重演。然而,平均GDP增速将升至5%,高于去年4.7%的预测值。这主要是因为近来处境艰难的俄罗斯和巴西境况将好转。
