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


Quick Take

The big winners over the past year in Arizona were the construction and leisure/hospitality industries, which both added more than 10, 000 jobs. Other fast-growing sectors include business services, financial activities and education and health services.

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.”

Whether of left or right, they present themselves as representatives of the common people against elites and unworthy outsiders; make a visceral connection with followers as charismatic leaders; manipulate that connection for their own advancement, frequently by lying egregiously; and threaten established rules of conduct and constraining institutions as enemies of the popular will that they embody.
The drama and the original game have a large fan base and enjoy great popularity in China, and even elsewhere in Asia.

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.

Rents at the top end of the market have fallen 6.4 per cent, more sharply than in any other city except Nairobi, according to Knight Frank, the property company. Last year, just after prices fell in September, Adidas, the sportswear group, leased a 13,000 square foot shop in the city for 22 per cent less than its former occupier, Coach, the accessories brand.
在实验中,参与者们被要求回忆一些他们在实验开始的时候看到的图片,其中,一半参与者在回忆之前进行了举重训练,另一半参与者没有进行这样的高强度活动。他们发现,参与了举重训练的人在记忆能力上有所提高。这项研究实现了运动研究上的独辟蹊径,其他研究的研究对象多是对有氧运动本身,研究时间跨度长达数,但是这项研究的研究对象却是人类记忆,在研究时也仅仅是要求参与者们花一点时间举重而已。研究人员证明了其实提升记忆力并不需要数个小时的锻炼。下次再有谁让你去举重或者去健身馆锻炼的话,你大概会想感谢他一番的吧?
