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.”

“让人们感到不幸福的原因有很多——从贫穷,失业,家庭破碎到身体伤害” 报告声称,“但在一些特定的社会中,慢性的精神性疾病却是幸福的‘头号杀手’。如果我们想要一个更加幸福的世界,我们需要花更多努力来关心人们的心理健康。”

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.

General Motors is helping fuel the improved jobs outlook in the Grand Canyon State. In March, the automaker announced plans to build the company’s fourth Information Technology Innovation Center in Phoenix suburb Chandler. GM is expected to hire 1, 000 workers, mainly consisting of software developers, database administrators and systems analysts for the new center. “The greater Phoenix area is a fantastic hub of emerging technical talent – from university graduates to working professionals, ” said GM CIO Randy Mott in a release announcing the move.
3. Dan Weiss “Fourteen” (Pi Recordings) There’s so much in “Fourteen,” the album-length composition by the drummer Dan Weiss: meticulous chamber maneuvers; avant-garde yowling; wordless vocals of new-music and northern Indian pedigree. More impressive than the expansive frame of reference is the fact that Mr. Weiss, marshaling about a dozen of his peers, spins it all into a flowing fabric.
