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


Quick Take

Indeed, last year produced the usual crop of new euphemisms for firing people. Infosys announced an “orderly ramp-down of about 3,000 persons”. Upworthy, a small media company, had the nerve to call sacking 14 people an “investment lay-off”. Otherwise, 2016 proved that the most egregious jargon is a sign not of failure, but of overexcitement.
2016年上半年,《实验心理学》期刊刊登了一项研究,题为“绘画效应:帮你在无障碍回忆的过程中构筑可靠强大的记忆力”。虽然这篇文章的题目看起来有点长、有点复杂,但是它证明的观点其实很简单,即把单词画出来的记忆方式能够建立更为优质牢固的记忆。研究的主持人进行了一个简单任务实验,在实验中,一位参与者要求画出简单的单词,比如常见的水果,接着,他被要求回忆自己画的是些什么单词。另一些参与者被要求重复朗读给出的单词。
A cheery New Year hold lots of happiness for you!给你特别的祝福,愿新年带给你无边的幸福、如意。

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.
