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.”

In month-on-month terms, consumer prices fell 0.1 per cent after having risen 0.7 per cent a month earlier.

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.

为Kinect开发《迪斯尼乐园大冒险》(Disneyland Adventures)和《精英:危险》(Elite: Dangerous)的开发商在ScreamRide中,将主题乐园经营发挥到了极致。玩家可以在游戏中建立夸张的过山车、云霄飞车和其他游乐设施,并进行试运营。游戏有三种玩法:工程师可以建设复杂的飞车,测试物理和重力极限;“尖叫骑手”则乘坐这些飞车,直接体验这种惊险与刺激——这有时会直接导致游戏人物死亡;而拆除专家可以用任何必要手段拆掉整个游乐园。随着《过山车大亨》(Roller Coaster Tycoon)等电脑游戏移植到了智能手机上,这一款次世代的过山车游戏可以让玩家有着时尚的互动体验。建设、体验和拆除过山车总是很有趣的,而ScreamRide则提供了多种方式,让你与朋友们共享这种兴奋之情。
