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.”

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.

戛纳电影节素以质问与嘲笑著名。在本届电影节上,《青木原树海》(Sea of Trees)成为第一部遭遇观众挑剔的电影。该片由格斯?范?桑特Gus Van Sant指导。在媒体放映场,《青木原树海》遭遇嘲弄的风暴,陷入了嘘声之海。由于这些发生在首映红毯前,恶评迅速传播,使得盛典蒙上阴影。娜奥米?沃茨(Naomi Watts )和 马修?麦康纳(Matthew McConaughey)走上红毯时,《每日电讯报》(Daily Telegraph)形容此场景为“极其糟糕却又引人瞩目的羞辱之途”。但是在随后的新闻发布会上,马修?麦康纳,这位来自德克萨斯的演员表情坦然,“每个人都有权倒喝彩,正如他们有权喝彩一样,”他说道。我相信我们都知道他的意思。
很难想象《迷失》中若是没有杰克·谢帕德作主角,这部剧会变成什么样。大概只有编剧真的这样写了,我们才会知道答案吧。美国广播公司引进这部剧后,杰克·谢帕德这一角色本该在坠机事件中遇难,接着将由凯特在这部剧中担任更多的领导角色。
