Ministers prepare for border restrictions as Britain concludes another lockdown | Instant News



Topline In an effort to control the spread of the most infectious variant of the coronavirus which is causing another wave of Covid-19 cases across the country, UK ministers are preparing to announce new restrictions on international travel on Tuesday to supplement measures lockdowns that prohibit everything but essential activities and travel for the foreseeable future. The UK will announce tighter border restrictions on Tuesday in a bid to control a recent outbreak of … [+] coronavirus case. Getty Images Key Facts Cabinet Minister Michael Gove said the government will release new border restriction plans on Tuesday, which is the first day of the third Covid-19 lockdown in England. “The message is very, very clear to British citizens that they should not travel,” the minister told Sky News. It’s unclear what the new restrictions will entail, although it is possible they will include Covid-19 testing on new arrivals – which ministers have long ruled out – as well as stricter quarantines and a travel ban abroad. When the lockdown was first announced on Monday, travel agency ABTA urged the government to support the struggling sector which it said has not received personalized government support. “It is true, of course, that the government is taking action to control the spread of the virus,” the group said, “but it must be accompanied by the right measures to support travel companies that have little or no means. to work.” Key Context In an effort to control an upsurge in Covid-19 cases across the country, British nations have imposed strict lockdowns restricting individual freedoms. Prime Minister Boris Johnson on Monday imposed a new lockdown in England, banning all activities except essential activities outside the home, including the closure of schools and universities. Scotland has issued similar stay-at-home orders, Wales has closed schools and Northern Ireland is expected to finalize tougher restrictions on Tuesday. It’s unclear when many of these restrictions will end, although politicians have said they will likely be in place until at least mid-February. Much of the new wave of Covid-19 is being driven by a contagious new variant, B.1.1.7., Which was discovered in south-eastern England and London in December. While the new variant isn’t considered vaccine resistant – manufacturers are testing it to make sure – or causing more serious illness, it is more infectious. This makes the virus harder to control and can overwhelm hospitals with an influx of cases.

EU countries set to adopt common travel rules amid pandemic | Instant News



European Union countries to adopt common traffic light system to coordinate travel across the 27-nation blocBy SAMUEL PETREQUIN Associated PressOctober 12, 2020, 1:08 pm • 3 min readShare on FacebookShare on TwitterSend this article ready to adopt a common system of traffic lights to coordinate movement across the bloc of 27 nations, but the return to full freedom of movement amid the COVID-19 pandemic remains far from being achieved. 151,000 EU citizens and plunging the EU economy into recession, the coronavirus also struck a blow at a cherished cornerstone of European citizenship, the free movement of people. When the virus struck in March, several EU countries have decided to close their borders to non-citizens without speaking to their neighbors, creating huge traffic jams and slowing the delivery of essential medical equipment. The cacophony, which also ravaged millions of tourists caught off guard by the virus, prompted the EU’s executive arm to push for a more unified approach. Last month, the European Commission presented proposals which were discussed and amended ahead of their expected approval by EU nations on Tuesday: “This new system will make things easier for citizens. I am happy that we found this solution together, ”said European Commission President Ursula von der Leyen. The key measure is a common infection map drawn up by the European Center for Disease Prevention and Control. It will classify European regions into green, orange and red zones based on the severity of the coronavirus outbreaks, taking into account new confirmed cases per 100,000 people and the percentage of positive tests. According to the latest proposal, the red zones should be areas where COVID-19 cases exceed 50 per 100,000 people over a 14-day period and the percentage of positive tests reaches at least 4%. Regions with a lower positive rate but where the total number of cases is greater than 150 per 100,000 will also be classified in red. Given the very high level of infections across the continent, this means that most of the bloc is expected to be classified in red. or orange. Harmonization stops before providing common rules for the EU’s orange and red zones. Travelers from Green Zones will not face limits on their travel, but EU national governments will continue to set their own restrictions such as quarantines or mandatory arrival tests for people coming from Orange Zones or The Commission has recommended mandatory tests for travelers from the most dangerous areas but cannot impose such a measure as health and border issues remain the prerogative of national governments. The aim was to create a way for EU states not to close their borders to each other. EU countries have yet to find a unified duration of self-isolation after exposure to virus, but they agreed to mutually recognize the test results. in all members. They will also develop a harmonized passenger tracking form for all means of transport. restrictions .——— Follow AP’s pandemic coverage at http://apnews.com/VirusOutbreak and https://apnews.com/UnderstandingtheOutbreak.

A new study about how Covid-19 can be spread through the air, even just to talk | Instant News


Washington (AFP): scientists have known for several months, the new coronavirus can be suspended in microdroplets excluded patients when they talk and breathe, but still there was no evidence that these tiny particles are infectious.

A new study conducted by researchers from the University of Nebraska, which was uploaded on the website of the medical working paper of this week showed, for the first time that SARS-cov-2 are taken from the microdroplets, which are defined as under the age of five microns, can replicate in the laboratory.

This strengthens the hypothesis that normal speak and breathe, not just coughing and sneezing, are responsible for the distribution of Covid-19-and that infectious doses of virus can overcome the distance a lot more than six feet (two meters) called the guiding principles of social distancing.

The results are still considered preliminary and has not yet appeared in a peer-reviewed journal, which will give more confidence to the methods developed by scientists.

The document was posted on the website medrxiv.org where the most advanced research during the pandemic was first published.

The same team wrote a paper in March showed that the virus remains in the air in the rooms of hospitalized Covid-19 patients, And this study will soon be published in the journal, according to the lead author.

“It’s actually quite difficult” to collect samples, said Joshua Santarpia, adjunct Professor at the University of Nebraska medical center ORP.

The team used a device the size of a cellular telephone for this purpose, but “concentrations are generally very low, your chances of recovery material small.”

Researchers took air samples from five rooms of bedridden patients, at the height of about a foot (30 centimeters) of the feet on my bed.

Patients were told that produces microdroplets, which become suspended in the air for several hours in what’s called “aerosols”, and some coughing.

The team managed to collect microdroplets as small as one micron in diameter.

Then they put the samples in the culture to get them to grow, to discover that three of the 18 samples tested were able to reproduce.

For Santarpia, this is proof that microdroplets that also travel much greater distances than large droplets, can infect people.

“It replicates in cell culture and therefore infectious,” said he.

The potential for transmission of coronavirus microdroplets were at some stage were incredible health authorities around the world.

Later, scientists started to change their opinion and admit it can be a challenge, which is the basis for the universal camouflage.

The world Health Organization was one of the last, changing his position, doing so on 7 July.

“I feel that the debate has become more political than scientific,” said Santarpia.

“I think that most scientists who work on infectious diseases agree that there likely is an air component, although we can argue about what size”.

Linsey Marr, a Professor at Virginia tech who is the leading expert on aerial transmission of viruses and was not involved in the study, said it was rare to get measuring the amount of virus present in the air.

“Based on what we know about other diseases and what we know so far about SARS-cov-2, I think we can assume that if the virus is infectious in aerosols, then we can be infected through inhalation,” said she. – AFP
