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


Quick Take

玛丽亚姆·谢里夫(Maryam Sharif)
Isolated in northern China, this virus was similar to the virus that spread before 1957. For this reason, individuals born before 1957 were generally protected, however children and young adults born after that year were not because they had no prior immunity. By January 1978, the virus had spread around the world, including the United States. Because illness occurred primarily in children, this event was not considered a true pandemic. Vaccine containing this virus was not produced in time for the 1977-78 season, but the virus was included in the 1978-79 vaccine.

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.”

Bangkok's 2014-15 fall from the top was largely put down to political instability in recent years.
HSBC economist Hongbin Qu said the survey pointed to lost momentum in China's manufacturing sector: He expects Beijing to respond with measures to counteract the slowdown.

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.

Small circulation also contributed to the monkey stamp's record price. Only five million "Golden Monkey" stamps were released for circulation in 1980, and they are exceedingly rare now.
