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.”

那么多的人视而不见,不承认事实。真相是泡沫无处不在,随时准备爆掉。证据越来越多,结论只有显而易见的一个:泡沫破灭的风险最高可达98%。2014年这次崩盘几乎是铁定要发生的,躲过这枚子弹的概率只有区区2%。

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.

"It is a massive jump in very little time: there were just about 30 cases when I became interior minister (in mid-2012), and 1,400 today," said Valls.

Swenson, Ali. The ability of customers to air their dirty laundry to the world via Twitter and Facebook has already changed the customer service game. A 2012 Nielsen survey shows more than half of all customers now turn to social media for redress; meanwhile, some 81% of Twitter users expect a same-day response to questions and complaints. But this fall, things got even more interesting: On Sept. 2, British Airways passenger Hasan Syed spent an estimated $1,000 to purchase several promoted Tweets blasting the company for losing luggage. With paid social media now in customers' arsenal, 2014 may mark the beginning of the end of abysmal customer service at major airlines, credit card companies, banks, and other repeat offenders, characterized by endless phone wait times and those automated "phone trees" (i.e., "Press 1 for English, 2 for Spanish, 3 to waste your entire afternoon on hold ...").
