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.”

这其中包括麦肯锡(McKinsey)。去年10月,这家咨询机构的500多名高级合伙人汇聚伦敦格罗夫纳豪斯酒店(Grosvenor House Hotel),启动了神神秘秘的领导层选举程序。下一阶段涉及该公司550名高级合伙人于1月对鲍达民(Dominic Barton)继任者的候选名单进行投票,之后在2月份对两名人气最高的候选人进行第二轮投票。鲍达民自2009年起执掌麦肯锡。

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.

But the runaway winner was Ford CEO Mark Fields, who began the year with the depressing news that his company was “transitioning from an auto company to an auto company and a mobility company”. He then went on to declare: “Heritage is history with a future.” He was so chuffed with this, he said it more than once. On hearing it repeated, I’ve concluded it is less gnomic than downright moronic. Mr Fields is thus my new Chief Obfuscation Champion.
值得庆幸的是,这些户籍规定正在发生改变。12月初,在中国中央经济工作会议上,与会代表建议给予农村居民城市户口,这也强有力地证明了户籍制度正在变化。温家宝总理于12月底呼吁,应加快户籍制度改革的进程。
