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.”
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.”
THE SLAP (NBC, Feb. 12) Jon Robin Baitz and Lisa Cholodenko are producers of this adaptation of an Australian mini-series about the fallout from a momentary loss of control at a backyard birthday party. The impressive cast includes Peter Sarsgaard, Uma Thurman, Thandie Newton, Brian Cox and Melissa George (who also appeared in the original).
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.”
Of course, these same new forces may also trigger a backlash and a reversion to old command-and-control ways of leading. The politicians who dominate the world stage are, depressingly, mostly cut from the old cloth, and the leadership challenges they face, from Brexit to North Korea, are particularly complex.
It’s wall-to-wall pure pop heaven, crackling with originality and dark humor, teeming with action sequences so perfectly timed and executed you almost want to run out of the theater on the spot so you can call a friend and rave about it — but you wouldn’t dare leave your seat because you wouldn’t want to miss a frame of this brilliant, pulse-quickening gem.

Fauzia, Miriam. “Yes — by an eyelash. Democrats will need to win an additional 24 seats, meaning they will have to hold on to all 12 Democratic districts that Mr Trump won last year and pick up the 23 Republican districts that voted for Hillary Clinton, plus one or two more for good measure. The math is not on the Democrats’ side, but history is. The president’s party almost always loses some House seats in the midterms, and sometimes loses big, especially when the president has an approval rating below 50 per cent. See Barack Obama in 2010.
