These are the advances in the coronavirus pandemic worldwide.
Scientists in Houston on Wednesday published an examination of more than 5,000 genetic sequences of coronavirus, showing the continued accumulation of mutations in the virus, one of which could possibly have made it more contagious.
This mutation is related to a higher viral load in patients in the initial diagnosis, the researchers found.
The study, which has not been peer-reviewed, was published Wednesday on the MedRxiv prepress server and appears to be the largest aggregation of genetic virus sequences in the United States to date. United Kingdom and, like the Houston study, concluded that a mutation that alters the design of the “advanced protein” on the surface of the virus can lead to a superior spread of this specific strain.
However, the new report concluded that these mutations had made the virus more deadly. All viruses collect genetic mutations and the maximum are negligible, according to scientists.
Coronaviruses such as SARS-CoV-2 are solid when viruses disappear because they have a reproduction mechanism when replicated.
But the mutation is a dice game, and with transmission so widespread in the United States, that it continues to see tens of thousands of new infections shown in both a day and both, the virus has had many opportunities to change, potentially with embarrassing consequences, according to the study, author James Musser of Houston Methodist Hospital.
“We have given this virus many opportunities,” Musser told The Washington Post. “Right now there’s a mass population. “
Scientists from Weill Cornell Medicine, the University of Chicago, Argonne National Laboratory and the University of Texas at Austin contributed to the study.
David Morens, virologist at the National Institute of Allergy and Infectious Diseases, reviewed the new study and said the effects involve the strong choice that the virus, as it moves in the population, has become more communicable and that this “could have implications. because of our skill in it. “
Morens noted that this is an exclusive item and that “you don’t need to overinterpret what it means. “But the virus, he said, could potentially respond, with random mutations, to interventions such as masking and social est esture, Morens said Wednesday. .
“Wearing masks, washing your hands, all these things are barriers to transmissibility or contagion, as the virus becomes more contagious, it’s statistically more effective at bypassing those barriers,” said Morens, Senior Adviser to Anthony S. Fauci, director of NIAID.

Finland tests coronavirus detector at Helsinki airport
HELSINKI – Finland has deployed coronavirus tracker dogs at the main foreign airport in the Nordic country as a component of a four-month trial of a proof-of-choice approach that can be a quick and cost-effective way to identify inflamed travelers.
Four dogs of other breeds trained through the Finland Odour Detection Association began painting Wednesday at Helsinki Airport as part of the government-funded test.
Helsinki Airport (@HelsinkiAirport) 22 September 2020
“It’s a very promising method. Dogs are very olfactory,” said Anna Hielm-Bjorkman, professor of equine medicine and small animals at the University of Helsinki.
“If it works, it will be a smart detection approach (coronavirus) in all other locations,” he said, in the directory of hospitals, ports, nursing homes, sports facilities and cultural events among imaginable locations where trained dogs can simply snout. . Work.
While researchers from several countries, including Australia, France, Germany and the United States, are also dogs as coronavirus detectors, the Finnish trial is among the largest to date.
Hielm-Bjorkman told The Associated Press that Finland is the country where, after the United Arab Emirates, and the first in Europe, dogs are assigned to suffer the coronavirus. A similar program began at Dubai International Airport during the summer.
Passengers who agree to write a loose check under the voluntary program in Helsinki have direct physical contact with a dog.
They are asked to rub their skin with a wipe that is then placed in a jar and delivered to a dog waiting in a separate cabin. Participating animals, ET, Kossi, Miina and Valo, have already been trained to run into cancer, diabetes or disease.
The dog only takes 10 seconds to sniff out the virus samples before giving the result of the verification by scraping one leg, measuring it down, barking or making its conclusion known. The procedure will be completed in one minute, according to Hielm-Bjorkman.
If the result is positive, the passenger is asked to perform a chain reaction using polymerosis, or PCR, coronavirus test, to check the accuracy of the dog.
Timo Aronkyto, deputy mayor of Vantaa, the capital of the region where the airport is located, said the program charges 300,000 euros ($350,000), an amount he described as “significantly lower” than other mass passenger arrival strategies.
The 4 tracker dogs are put to paint at the airport in turn, with two service at a time while the other two have a break.
“Dogs want to rest from time to time. If the smell is mild, do not wear the dog too far. But if there are many new smells, dogs get more easily tired,” said Anette Kare of the Finnish Odour Detection Association, also known as WiseNose, as she gently caressed ET, her white shepherd.
Fauci says scientists can tell if the vaccine is effective until December
WASHINGTON – Dr. Anthony Fauci says that until the end of this year, government scientists deserve to know if they have an effective vaccine that opposes COVID-19.
Fauci is one of the elders who testified before the Senate Committee on Health, Education, Labour and Pensions on Wednesday.
As the government’s leading infectious disease expert, Fauci has been realistic about the risks of coronavirus, but also positive about customers of a Fauci vaccine saying that others who from the virus expand antibodies that oppose it, giving him confidence that a vaccine that triggers the immune formula to work.
Fauci says several types of vaccines are in the latter phase in the United States. A single-dose candidate is the recent maximum trial, which requires thousands of volunteers.
Early knowledge shows fewer COVID outbreaks in schools than was feared in the first place
Thousands of academics and teachers have contracted COVID-19 since schools opened last month, however, until now, public fitness experts have discovered little evidence that the disease is spreading through internal buildings, and infection rates are much lower than those discovered in surrounding communities.
This early evidence, experts say, suggests that opening a school might not be as difficult as many have feared and may also be just principal advisors while loading the rest of what is already an unprecedented school year.
“Everyone was afraid that there would be explosive outbreaks of transmission in schools. In colleges, there have been. We have to say that to date, we haven’t noticed it in younger people, and that’s a vital observation,” Michael said. Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota.
This does not mean that the threat of coVID-19, coronavirus disease, is zero, poor and inconsistent reports in many parts of the country mean that experts do not yet have a complete picture of the scenario and that maximum schools have only been open for a few weeks. It is not yet transparent to what extent the effect of COVID on schools is similar to policies within schools, such as mandatory use of masks.
Most of the country’s largest districts have been opened with fully distance learning, so the knowledge to date comes largely from small communities, and the pandemic may worsen as flu season and winter approach. .
But the fact that giant sections of the country opened up to school in users while others did not offer the most cautious districts the chance to see how things were going by making plans for their next steps.
On Wednesday, Brown University researchers, in collaboration with administrators, published their first set of knowledge from a new national COVID-19 reaction knowledge panel, created to track COVID cases, and discovered low degrees of infection among academics and teachers.

Lufthansa to implement passenger coronavirus testing, a resolution industry leaders hope can save air travel
German airline Lufthansa plans to begin providing immediate coronavirus testing to passengers in October, a corporate executive said Tuesday, according to Reuters.
The new antigen controls will first only be available to first-class and business class passengers because materials are limited, journalists Bjoern Becker, the company’s senior director of product management, told reporters, who added that Lufthansa is also considering the option. to open checkpoints at airports in the United States and Canada.
Rapid antigenic testing is affordable to produce, but is sometimes less accurate than polymer chain reaction (PCR) tests and can produce false negatives. The U. S. Food and Drug Administration. He has stated that all negative effects of antigen testing are shown through a PCR test.
While the call abroad has sold out, some in the industry expect quick verification before taking a flight to be more appropriate than the 14-day remote perspective. The International Air Transport Association on Tuesday called for quick and affordable verification for all. noting that many potential customers are discouraged by quarantine needs and a constantly changing patch of restrictions.
“Quarantine measures are ending the recovery of the industry,” Alexandre de Juniac, the organization’s director and CEO, said Tuesday. “About 83% of readers in a recent survey of 11 markets said they would not do so if there was a possibility of being quarantined. at his destination. It’s a very transparent sign that this industry won’t recover until we find an option to quarantine.
Public opinion polls show that an overwhelming majority of travelers are in a position to be monitored as part of the travel procedure and that negative control of the coronavirus deserves to be mandatory for all travelers, said De Juniac, who noted that two pharmaceutical companies, Roche and Abbott, have developed immediate antigenic controls that produce effects in minutes.
“The speed at which the functions progress tells us that we will have drop-down functions in the coming weeks,” he said.
Dubai sees an increase in cases
DUBAI, United Arab Emirates – The United Arab Emirates has recorded 1,083 new coronavirus infections, peaking four months after business reopening across the country.
This brings the total number of people shown in the United Arab Emirates to 87,530 and 406 deaths.
While the peak follows a competitive coronavirus screening campaign, the country has noticed such high infection rates since mid-May.
In the months that follow, the government eased the restrictions. Dubai, the region’s business center, has reopened its airport to foreign travellers and schools have resumed face-to-face education.
Rising restrictions in the Spanish capital can be extended to more areas
MADRID – The Madrid fitness government may increase the movement restrictions it has imposed in the spaces of the Spanish capital with the highest rates of coronavirus infection to more communities.
About 860,000 Madrilenians already have to justify themselves before 37 neighborhoods, usually working-class neighborhoods. People have complained that the restrictions stigmatize the poor.
The region’s deputy director of fitness, Antonio Zapatero, said a resolution on new measures would be announced on Friday, adding imaginable visitor limits in restaurants.
Zapatero said the scene of the epidemic in the Community of Madrid, which has a population of 6. 6 million, is a “sustained increase”.
Madrid had a contagion rate of 772 cases consisting of 100,000 inhabitants in 14 days, 3 times the Spanish national average of 287 cases consisting of 100,000 inhabitants.
Spain recorded 241 deaths more similar to the virus on Tuesday, bringing the total number of deaths shown to 30,904.
UK criticised following announcement of new modest restrictions for England
LONDON – Prime Minister Boris Johnson criticized Wednesday after introducing new curfews in pubs and restaurants in England and encouraging remote paintings, restrictions that can remain in place for six months.
In his announcement Tuesday, Johnson described a number of new limitations for England: starting Thursday, pubs and restaurants will offer only table service and will have to close at 10pm Johnson also said that if other people can paint from home, they . . . a change of direction after past government tension so that others return to their paint sites and help revive urban centers.
The measures were more modest than those allegedly discussed, adding a two-week mini-lock, however, they have been the subject of complaints from commercial and industry teams. hotel industry, which are preparing for economic consequences.
Some said Wednesday that the measures were insufficient. In statements to the BBC, epidemiologist John Edmunds described the premature closure of pubs as “quite trivial. “
“Overall, I don’t think the measures have gone far enough,” he said.
The accumulation of infections and hospitalization rates has raised considerations for a momentary outbreak of new coronavirus cases. On Monday, the most sensitive government scientists predicted that the country could face 50,000 cases of coronavirus consistent with the day until mid-October if it stays on. their existing trajectory.
New cases of coronavirus are shrinking in India
NEW DELHI – India has added 83347 new cases of coronavirus in more than 24 hours, a decrease after a record 97,000 a week ago.
The last six days have shown some decline in new cases, but Wednesday’s accumulation reported through the Department of Health brought the national total to more than 5. 6 million, which is about to surpass the total United States in a matter of weeks.
The ministry said another 1,085 people had died in the last 24 hours, for a total of 90,020.
The Ministry of Health says more than 80% of the inflamed have recovered, leaving less than one million cases active.
Balram Bhargava, director general of the Indian Medical Research Council, said vaccines with 50% efficacy will be used against coronavirus.
This is the benchmark established through the World Health Organization, because no respiratory disease vaccine is 100 percent effective, he told reporters On Tuesday.
