The US remains home to the biggest brands and the value of its top 10 increased by 10 per cent to $1.3tn in 2016. The top 10 UK brands, headed by Vodafone, lost 8 per cent of their value. Those in continental Europe — led by Germany’s SAP software group — rose 5 per cent. Finally, the $360bn value of Asia’s top 10 brands, headed by Tencent, China Mobile and Alibaba, was only 10 per cent lower than the value of the top 10 in continental Europe and the UK combined.
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.”
But what drives the underlying optimism or pessimism? Koudijs, working with Hans-Joachim Voth at the UniversitatPompeuFabra in Barcelona, found surprising answers.

Swenson, Ali. Despite the promise of downloadable courses, teaching for officially recognised qualifications continues to be a classroom-based activity undertaken in the real world. Start-ups have taken the attitude that if they cannot beat the universities and colleges at their own game with new methods of delivery, they should join them in partnerships. As a result, they have been busy getting examining boards to endorse their online courses so that they can count towards a bachelor’s or master’s qualification. Associated Press. 7 Jul 2020.
