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


Quick Take

Commodity-linked sectors have been especially hard hit in recent months. Mining-sector earnings tumbled 23 per cent last year. Oil and petrochemical refiners also saw profits slammed. Despite the fall in crude prices, many refiners remain subject to crude prices agreed to before the recent price drop, even as prices for their output fall.
TOGETHERNESS (HBO, Jan. 11) HBO’s Sunday night comedy block already covers early-20-something New York women (“Girls,” beginning its fourth season the same night) and late-20-something San Francisco gay men (“Looking,” beginning its second). Now it adds 30-something Los Angeles straight people in this sometimes bleakly comic half-hour from Jay and Mark Duplass, the brothers behind quirky films like “The Puffy Chair” and “Baghead.” Mark Duplass and Melanie Lynskey play a married couple sharing a house with his best friend (Steve Zissis) and her sister (Amanda Peet).
The UK’s Warwick Business School recorded the best progression at the top, moving up from 16th to ninth place, while the Shanghai Advanced Institute of Finance (Saif), based at JiaoTong University, enjoys the bestprogression overall, jumping from 28th to 14th place.

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.”

毫不奇怪,信贷具有“助周期性”。当资产价格一片繁荣时,乐观的贷款机构倾向于发放更多贷款,进而加剧市场的狂欢。当资产价格下跌时,贷款机构会控制风险,有时这种做法会加速下跌。

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.

He Fan, economist at Caixin, said:“This shows that the macro economy has moved further toward stable growth and the economic structure is improving. Future fiscal and monetary policies must be coordinated and large-scale stimulus should be avoided as much as possible.”

Fifteen Chinese nationals have been charged with developing a fraud scheme in which they paid imposters to take entrance exams, including the SAT, and gained acceptance to elite American colleges and universities, the US Department of Justice said on Thursday. Conspirators were paid up to $6,000 each time they used counterfeit Chinese passports to trick test administrators into thinking they were the person who would benefit from the test score, a federal grand jury charged.重点单词
