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


Quick Take

Nothing tops the insensitivity and stupendous lack of awareness as Lohan's insensitive post five months ago.
“I am proud of my position as a boss, as a person that runs my own company,” Perry told FORBES for our Celebrity 100 cover story this past summer. “I’m an entrepreneur. … I don’t want to shy away from it. I actually want to kind of grab it by its b---s.”

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.”

上周一晚间,在MSNBC的一档节目中,主持人雷切尔·玛多询问前国务卿希拉里,她是否会做出和加拿大新总理贾斯汀·特鲁多今年早些时候类似的承诺?
《泰晤士高等教育》专刊的编辑菲尔·巴蒂说道:“中国采取了强有力的政策,且背后又有雄厚的资金支持,才能打造这些世界一流的大学。2015年,中国就宣布将实施‘卓越计划',计划在2020年之前打造六所可以跻身世界一流行列的高校。”

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.
