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.”

Phil Baty, editor of the rankings, said: "it seems that China's relentless march up the global league tables has stalled, after making major gains in recent years. This new data shows just how hard it is for emerging powers to break into the traditional global elite."
In 2013, the total number of applicants who qualified for the national service exam reached a record 1.52 million. In 2014, the total number decreased for the first time in four years to 1.41 million, the People's Daily website said.

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.

至于英国,官方虚构数据同样盛行。英国国家统计局(Office For National Statistics)周二公布,以由来已久的零售价格指数(RPI)衡量,去年12月英国通胀率上升至4.1%。该数字纯属胡扯,英国国家统计局对此心知肚明。该机构告诉人们RPI“没有达到规定标准”,不能作为合格的通胀指标,但自2012年以来该机构一直拒绝采取措施来改善该指标并使之贴近3%的整体通胀率。
This year's lift was slower than the 6.5% rise in 2016, which is attributed to moderating economic growth and a rapidly aging society.
