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


Quick Take

One side of the capsized Eastern Star was rolled above water at 7:30 am Friday, as rescuers worked through the night to right the upturned ship in the Yangtze River. The side that has emerged shows "Eastern Star" in Chinese character on the hull.
But economists generally expect the momentum of the recent past to resume and continue once storm distortions abate. The 45 economists who responded to The Wall Street Journal's latest monthly forecasting survey saw the jobless rate falling to 7.8% by next June and 7.5% by the end of 2013. Some say job growth could accelerate from its slow pace. 'I think businesses are going to have to hire,' said Bob Baur, an economist with Principal Global Investors.[qh]

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.”

“Domestic demand expanded at a sluggish pace while new export order growth eased to a five-month low ... We continue to expect further monetary and fiscal easing measures to offset downside risks to growth.”
World Health Organisation declared that the cluster of microcephaly cases and other neurological disorders were a public health emergency of international concern, it was a rallying cry for the international community to respond.

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.
