A new variant of coronavirus, detected first in England and now extending worldwide, including United States, “can be associated with a mayor mortality rate“, the fourth British Prime Minister, Boris Johnson, said at a press conference.
The new mutation is contagious with more facilities than the coronavirus that started the pandemic. Some studies have suggested that it is between 50 and 70% more infectious. United States registered in December finals the first case confirmed of the variant, known as B.1.1.7, but the experts have said that now is not even more lethal of the known agreement.
At the Downing Street, Johnson Press Conference and his assessors, there is little information about the even higher mortality rate.
Without embarrassment, the chief assessor of England, Patrick Valance, gave an example. In a group of 1000 men from 60 years or more, the original virus matures to 10. The new cepa, index, matures to 13 or 14.
The news came when there were other mutations of the virus, detected in South Africa and Brazil, which generate concern about the effects that can be had on the vacancies now to freeze the contagion.
Preoccupation with the efficiency of vacancies
Sanitary experts have ensured that the variant detected in the United Kingdom does not show resistance to the currently approved vehicles (Pfizer-BioNTech and Modern).
This week, without embarrassment, the scientific studies will begin to show concern for another variant of the virus, located in South Africa and known as 501Y.V2. Some experts have potential for that is a mutation that has not been registered in the United States, can complicate the response to the pandemic.
This preoccupation is based on studies published this March that suggest that the mutations in the South African variant, present in at least 23 countries, can provoke a mayor risk reinforcement by COVID-19 in the people he has been with virus and deberían have developed an immune system.
The scientists have not confirmed that this variant is more contagious, although the evidence points to its direction. Also the preoccupation that 501Y.V2 can complicate the response to existing treatment against the COVID-19.
For example, Regeneron, a company that developed a cocktail of monoclonal anticoagulants as a therapy for patients with encephalitis, informed that 501Y.V2 could evade one of the antidotes in its cell.
But the most alarming quiz is the possibility that these mutations can limit the effectiveness of existing vacancies, one of the best measures to control the pandemic.

The studies published on the following March that this variant is less susceptible to the anti-cancer creams due to the natural infection and the vacancies of Pfizer-BioNTech and Moderna.
Michel Nussenzweig, Immunologist at the Rockefeller University of New York, who conducted one of the studies, told The New York Times that existing vacancies would prevent more serious symptoms and that people would be required to receive them:
“If the objective is to keep the people going to the hospital, then it will work well,” he said.
Pero while the vacancies do not prevent people from becoming infected or asymptomatically with the variants, advirtió Nussenzweig; “It is possible that we will not know if they are infected”. If you are infected you can transmit the virus to other people who have not been vaccinated, the virus coexists with live viruses.
South African scientists will be informing you at the end of the week that you will be conducting laboratory exams for a group of 44 coVID-19 submarines, including the use of these vacancies to destroy the new variant.
The samples that were taken against the variant were taken from patients who were hospitalized. These patients have higher blood levels than the neutralizing antipyretics (the subset of antecedents necessary to ward off the virus and prevent the infection) that only live in hospitals.
The results “strongly suggest that Various mutations that we see in the South African variant have a significant effect on the susceptibility of this virus to neutralization“, said Penny Moore, virologist at the National Institute of Transmissible Subjects of South Africa, who directed the study earlier.
Another preoccupation mutation in Brazil
The federal government has suspended some roads in the country where it has cut new variants of COVID-19, such as the United Kingdom and Brazil.
These judges, President Joe Biden, have issued a decree of executive orders that includes restrictions on international travelers who arrive in the country. The new Administration will require negative COVID-19 exams to enter national territory. The travelers will also have to stay in quarantine for a while.
Además de la que circula en Sudáfrica, the variant of Manaus, Brazil, known as P.1, also is a source of preoccupation.
Investigators in this country document the case of a COVID-19 patient for 45 years without any other concerns that, even though he had first contact with the nurse, he wanted to infect with the new variant. The patient experiences a more serious illness the second time.
Although the evidence is currently limited, “there will be important implications for public health policies, vigilance and immunization strategies”, according to Brazilian scientists.

In Manaus, however, it is estimated that more than three quarters of the population were infected with the virus during an outbreak, the cases were accumulating new and the hospitals were in disrepair. Investigators suspect that a cause could be the new variant.
According to the Centers for Control and Prevention of Injuries, the information on the characteristics of the new variants in the world is surging rapidly.
“Scientists are working to learn more about the facility with which they can propagate, if they can cause more serious illness and if the vacancies are currently authorized to protect persons against them”, he assured the CDC in its official page. “At the moment, there is no evidence that these variants cause a serious illness or a mayor’s death risk,” he added.
More than 400,000 people in United States caused COVID-19 initiated the pandemic in the country in March 2020.
