COVID-19 Nasal Swab Test Does Not Cause Risk of Infection

去年12月,包括中国商务部、中国央行在内的四个政府部门表示,将收紧对房地产、酒店、影城、娱乐业、体育俱乐部等领域的“非理性”对外投资项目的审查。
的确,这种兴奋会导致上述团体的成员做出不切实际的声明。一些比特币开发者和投资者宣称,五年内,各大银行将接受比特币。比特币钱包Blockchain公司首席运营官彼得o史密斯承认,上述说法有些夸张。史密斯表示:“我听到很多预测称,很快全世界都将使用比特币,这些预测大都不现实。我们正试图做的,是一个相当大胆的生态系统,所以这将需要很长的时间。”

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.”

The Fed last month laid out a timetable to slow the pace of its bond purchases throughout the year. The central bank, which had been soaking up $85 billion a month in Treasurys and mortgage-backed securities since late 2012, plans to reduce the pace of purchases by $10 billion at each meeting until it is no longer buying bonds at year-end.

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.
