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.”
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.”
As of mid-July, there were about 50,000 stores running on Bigcommerce, which have collectively sold close to $4 billon using the platform. The developer has typically added new customers one-by-one. However, a deal it struck in early July with eBay positions its service as the preferred migration path for two Magento products that will be discontinued in February 2015, Go and ProStores. Bigcommerce previously migrated more than 5,000 merchants off ProStores, and the deal could potentially bring up to 10,000 more.

Fauzia, Miriam. “我们总会不断地去思考着NBA一个赛季接着一个赛季的时间流逝，原因也很明显。在流逝的过程中，每一项事物都是有联系的，整个过程就是一个连续体。这就是我们记住在一个赛季当中所发生事情的方式。当我们翻看日历，从1月1日到12月31日，回顾一下我们在这个过程中学到了什么，对我们来说是很有好处的。而且，很多人说NBA赛季的“非正式开端”是圣诞节，也正是因为新年很快就要开始了。下面是我们在2017年里所学到的关于nba的经验教训。 USA Today. 9 July 2020.
