BERLIN/PARIS
(Reuters) - French President Emmanuel Macron and German Chancellor Angela
Merkel ordered their countries back into lockdown on Wednesday, as a massive
second wave of coronavirus infections threatened to overwhelm Europe before the
winter.
World stock markets went into a dive in response to the news that
Europe’s biggest economies were imposing nationwide restrictions almost as
severe as the ones that drove the global economy this year into its deepest
recession in generations.
“The virus is circulating at a speed that not even the most pessimistic
forecasts had anticipated,” Macron said in a televised address. “Like all our
neighbours, we are submerged by the sudden acceleration of the virus.”
“We are all in the same position: overrun by a second wave which we know
will be harder, more deadly than the first,” he said. “I have decided that we
need to return to the lockdown which stopped the virus.”
Under the new French measures which come into force on Friday, people
will be required to stay in their homes except to buy essential goods, seek
medical attention, or exercise for up to one hour a day. They will be permitted
to go to work if their employer deems it impossible for them to do the job from
home. Schools will stay open.
As in the darkest days of spring, anyone leaving their home in France
will now have to carry a document justifying being outside, which can be
checked by police.
Germany will shut bars, restaurants and theatres from Nov. 2-30 under
measures agreed between Merkel and heads of regional governments. Schools will
stay open, and shops will be allowed to operate with strict limits on access.
“We need to take action now,” Merkel said. “Our health system can still
cope with this challenge today, but at this speed of infections it will reach
the limits of its capacity within weeks.”
Her finance minister, Olaf Scholz, posted on Twitter: “November will be
a month of truth. The increasing numbers of infections are forcing us to take
tough countermeasures in order to break the second wave.”

India's high use of antigen tests
risks underestimating COVID-19 spread, says diagnostician
October 28,
202011:44 AM
NEW
DELHI (Reuters) - Fast but less accurate “rapid antigen tests” now account for
60% of all coronavirus tests in India, the head of a top diagnostic firm
estimated on Wednesday, warning that such a high use could misrepresent the
actual spread of the infection.
Antigen devices return results in about 15
minutes compared with several hours for the reverse transcription polymerase
chain reaction (RT-PCR) method, a laboratory-based process which the U.S.
Centers for Disease Control and Prevention calls the "gold standard here "
for COVID-19 detection.
Whereas antigen tests typically detect the
virus around 80% to 90% of the time, lab-based tests detect the virus more than
95% of the time, say regulators and health experts in countries like the United
States.
As a consequence of the reduced accuracy,
India’s high use of antigen tests compared with a global use of around 10%,
risked underestimating the spread of coronavirus, according to the founder of
Mumbai-based Thyrocare Technologies Ltd, one of India’s top-three diagnostic
chains.
“It’s a wrong scale used to assess” the
extent of the spread of the virus, Arokiaswamy Velumani told Reuters in a phone
interview.
Though the total number of coronavirus cases reached close to 8 million
on Wednesday, India’s official tally shows daily new cases have dropped sharply
since a mid-September peak.
Velumani said Thyrocare’s centres are now receiving only about 2,500
samples a day for RT-PCR tests, down from a high of about 7,000 in September.
The health ministry and the Indian Council of Medical Research did not
immediately respond to emails from Reuters seeking comment on Velumani’s
comments.

Over 80 percent of COVID-19
patients have vitamin D deficiency, study finds
Vitamin D
deficiency was more prevalent in men
Date: October 27, 2020
Source: The Endocrine Society
Summary: Over 80 percent of 200 COVID-19 patients in a
hospital in Spain have vitamin D deficiency, according to a new study.
Over 80 percent of 200 COVID-19 patients in a hospital in Spain have
vitamin D deficiency, according to a new study published in the Endocrine
Society's Journal of Clinical Endocrinology & Metabolism .
Vitamin D is a hormone the kidneys produce that controls blood calcium
concentration and impacts the immune system. Vitamin D deficiency has been linked
to a variety of health concerns, although research is still underway into why
the hormone impacts other systems of the body. Many studies point to the
beneficial effect of vitamin D on the immune system, especially regarding
protection against infections.
"One approach is to identify and treat vitamin D deficiency,
especially in high-risk individuals such as the elderly, patients with
comorbidities, and nursing home residents, who are the main target population
for the COVID-19," said study co-author José L. Hernández, Ph.D., of the
University of Cantabria in Santander, Spain. "Vitamin D treatment should
be recommended in COVID-19 patients with low levels of vitamin D circulating in
the blood since this approach might have beneficial effects in both the
musculoskeletal and the immune system."
The researchers found 80 percent of 216 COVID-19 patients at the
Hospital Universitario Marqués de Valdecilla had vitamin D deficiency, and men
had lower vitamin D levels than women. COVID-19 patients with lower vitamin D
levels also had raised serum levels of inflammatory markers such as ferritin
and D-dimer.

Study: Loss of smell in COVID-19
far more common than thought
Oct. 28, 2020 /
3:05 AM
Loss of smell is common in COVID-19, but fewer people say they have this
symptom than objective tests reveal, a new study finds.
In fact, about 77% of COVID-19 patients who were directly measured had
smell loss, but only 44% said they did, researchers found.
Direct measures of smell involve having patients smell and report on
actual odors, while self-reporting includes getting data through patient
questionnaires, interviews or electronic health records, the study authors
explained.
"Objective measures are a more sensitive method to identify smell
loss related to COVID-19," said study co-author Mackenzie Hannum, a
postdoctoral fellow at Monell Chemical Senses Center in Philadelphia.
Subjective measures, "while expedient during the early stages of
the pandemic, underestimate the true prevalence of smell loss," said
Vicente Ramirez, a doctoral student at the University of California, Merced,
and summer intern at Monell.
The research suggests subjective measures underestimate the true extent
of smell loss and that it may be an effective tool for diagnosing COVID-19
early, the authors said in a Monell news release.
For the study, the researchers reviewed previously published studies on
COVID-19 and loss of smell.
Their findings were published online recently in the journal Chemical
Senses.
Senior author Danielle Reed, associate director at Monell, suggested
that "measuring people for smell loss may become as routine as measuring
body temperature for fever."

Tesla Autopilot 'a distant
second' to GM's Super Cruise in hands-free test: Consumer Reports
October 28,
202010:09 AM
DETROIT (Reuters) - General Motors Co's GM.N Super Cruise once again
edged Tesla's TSLA.O
Autopilot in an evaluation of 17 vehicles equipped with active driving
assistance systems (ADAS) by Consumer Reports, the testing organization said on
Wednesday.
A Tesla Model Y fitted with Autopilot
finished “a distant second,” the group said, to a Cadillac CT6 equipped with
Super Cruise, which GM is rolling out to more than 20 vehicles - including its
new Hummer electric pickup truck - over the next three years.
Safety and insurance researchers have
frequently warned of the risks of consumers overestimating ADAS systems’
abilities, a misconception increased by some automakers calling their products
Autopilot, ProPilot or Co-Pilot.
In 2018, the Cadillac CT6 with Super Cruise
scored higher than a Tesla Model 3 with Autopilot, in a Consumer Reports test
of just four vehicles equipped with ADAS.
In the latest test, conducted this summer on
a track and on public roads, the Cadillac scored 69 points out of a possible
100, while the Tesla scored 57. A Lincoln Corsair equipped with Ford Motor Co's
F.N Co-Pilot 360 system,
finished third with 52.
The critical difference in the Super Cruise
system is a driver-facing infrared camera to make sure he or she is paying
attention to the road and is ready to take over manual control when necessary,
said Kelly Funkhouser, head of connected and automated vehicle testing at
Consumer Reports.
The group noted that Autopilot can shut off
abruptly in some situations, while Super Cruise did a better job of notifying
the driver when the system is disengaging.
In recent European safety testing, a Tesla
Model 3 with Autopilot placed sixth out of 10 systems, getting high marks for
performance and ability to respond to emergencies, but falling short on its
ability to maintain a driver’s focus on the road.
