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


Quick Take

Even though we are apart, you are in my heart this season.千山万水,隔不断我在佳节对你的思念。
Participants in the study were between the ages of 18 and 44 and were asked to run twice – with and without shoes. After completing their quick runs, researchers found that the heart rate and overall run speed of each participant had no effect on memory, but the presence of shoes or bare feet did. The researchers have hypothesized that the need to engage the mind while running barefoot to avoid pebbles or other impediments could have a positive impact on a person's ability to remember things. If you're an adventurous person, you might try taking a barefoot jog around the block before your next test or before you need to remember something important.

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.”

许多分析师或许会对有关他们低估美联储的说法感到愕然。如今人们在谈论新兴市场资产时,最常提到的两个相关因素就是美联储和中国,以及它们将来造成负面冲击的风险。

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.

Mr Williams notes that early November data from the likes of Brazil, Vietnam, Taiwan and Chile suggests the picture has continued to improve since October.

This is not to take anything away from Tesla, which has demonstrated that it can create and manufacture a complex and sophisticated product with demonstrated customer appeal. But its own internal forecasts, as well as the swelling of its share price, are based on the expectation that the future will unspool in an orderly fashion identical to the recent past. That’s a dangerous assumption to make – for several reasons:
