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


Quick Take

中国教育部体卫艺司司长、中国足球协会副主席王登峰表示,足球专家们正在为小学和初中设计超过360种训练项目。
习及一些领导人员已经明确指出,中国将会进行可持续发展、内需为依托的经济转型,为此中国可以忍受稍微慢一些的增长速度。于是一些预言家马上就下出结论,认为中国经济会因而立即大幅减速。特别是中国曾经有过这样的先例。在1978到1993年中国领导人进行改革开放,然而在政策施行的最初阶段中国经济曾经遭遇不稳定。
萎靡不振的不光是那些挑选个股的基金。截止12月1日,对冲基金整体回报严重落后于市场。彭博收集的数据显示,对冲基金平均同比上涨了2%,其回报率也就勉强赶上无风险10年期美国国债的票面利率。2014年将有1000多只基金倒闭,是自2009年以来破产清算最多的一年。

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.”

Here's how the pay of prime ministers and presidents of the world's biggest economies stacks up, according to official data and converted into US dollars at market rates.
Jack Ma and his family's total wealth in IT industry was 195 billion yuan, followed by Tencent Holdings founder Pony Ma, whose wealth increased by 30% year-on-year to 134 billion yuan.

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.

China’s trade with the rest of the world fell sharply in October from a year earlier, with imports of raw materials particularly hard hit as slowing Chinese investment feeds through into weaker demand in the world’s biggest trader of goods.

Analysts say headline import figures may start to improve in the coming months since commodity price falls were particularly pronounced at the end of 2014, which will mean smaller year-on-year falls in Chinese imports in value terms.
