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


Quick Take

与去年相比,亚马逊(Amazon)、星巴克(Starbucks)和Facebook今年的品牌价值飙升。亚马逊的品牌价值增长59%,至990亿美元,排名第七,Elspeth Cheung表示,这在一定程度上源于其创造需求、而不仅仅是满足需求的能力。她表示,亚马逊的一小时送货服务对其他零售商加快送货速度构成压力,同时这家在线零售商进入物流领域对联合包裹(UPS)、联邦快递(FedEx)以及DHL等快递公司构成威胁。
筹备IPO交易的公司正在增多,尽管今年在美国高调上市的Snap(旗下拥有Snapchat)表现不佳,同时投资者担忧欧元不断走强可能遏制欧洲企业的盈利复苏。

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.”

She said: "I am extremely surprised and overwhelmed. I just want to start by saying what an incredible year for women in film. These categories are so crowed and crammed with incredible integrity and skill and I feel prouder than ever to be included."

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.

One might expect that online programmes would appeal proportionately more to women than full-time programmes due to their flexibility. How-ever, data from the 2016 rankings show that women account for 30 per cent of enrolled students compared with 35 per cent for full-time programmes.
12. 最有希望的迹象。有段时间,你会觉得现状已经改善了,人们可以公开大声谈及业内的歧视现象。维奥拉·戴维斯(Viola Davis)出来说话,詹妮弗·劳伦斯(Jennifer Lawrence)公开谈起,自己比片中的合作男星片酬少。“我不想被视为‘难搞’或者‘被宠坏了’,”她在简报《伦尼》(Lenny)中为许多人发言,其中包括许多薪酬更低的人们。
鉴于FIFA世界杯将于2018年在俄罗斯举办,届时的旅游成本会大大提高,所以选择在2017年去可谓是明智之举。
