how much more contagious the British strain is / Argentina News


The new variant of covid-19 is noted for its high degree of transmissibility and a case has already been reported in Argentina. The details

The doctor in Virology Carolina Torres, researcher at Conicet and member of the team of the interdisciplinary consortium of Argentine scientists who reported the entry into the country of the UK SARS-CoV-2 virus variant in a traveler, he remarked that “the important thing is that there is no community transmission” and that, according to the WHO, this strain “would be between 40 and 70% higher in transmissibility”.

Torres is part of the PAIS Project (Argentine Inter-institutional Genomics Project of SARS-CoV-2), a team of scientists coordinated by Mariana Viegas, from the Ricardo Gutiérrez Children’s Hospital Virology Laboratory, created by the Ministry of Science, Technology and Innovation .

From there a report was presented where today it was reported that the variant of the SARS-CoV-2 of the United Kingdom was identified through a PCR analysis carried out on a passenger who arrived on a flight to Ezeiza, from Frankfurt, Germany.

“There were different studies on the evolution of the VOC202012-01 variant, lineage B.1.1.7, based on epidemiological information, but from different places, and they all reached the conclusion that it would be a 50% higher transmissibility,” he told Télam today the biochemist Torres.

And he added that last Monday, the team of researchers participated in a meeting, as an international consultancy, and the World Health Organization (WHO) said that “this variant has a transmissibility power of between 40 and 70%“based on background based on studies from England.

The British strain spreads around the world

This variant entered a lot of countries, about 54 so far and almost half of them became community, but it is being followed to see what is causing it, “explained the scientist.

The important thing to highlight at the local level, according to Torres, is that the case detected in Argentina is “isolated, it was detected when entering the country and is not of community transmission, since the Argentine tourist fulfilled home isolation without close contacts” .

In turn, the scientist explained that “the behavior of the variant is studied with the local population once there is community transmission and it is verified how the virus behaves in people according to the place of origin.”

Therefore, he added, “we do not know if this variant would behave in the same way in all populations, but according to the studies that were carried out, it was not shown to have the capacity to generate a more severe disease.”

“What is always good to remember, is that We must strengthen protection measures because although it does not generate greater deaths, indirectly, it brings increased risk of new infections and more deceased“, he concluded.

Global alert: the British strain has already been detected in 54 countries.

The UK strain, in the country

The Minister of Science, Technology and Innovation, Roberto Salvarezza, confirmed this Saturday that the UK variant of SARS-COV-2 was detected in a traveler from Frankfurt and the studies carried out to date have shown that although it has a “greater power of transmissibility, it does not aggravate the clinical picture of the disease.”

The inter-institutional Consortium for Genome Sequencing and genomic studies of SARS-COV-2, created by the Ministry of Science, “detected the entry into the country of an Argentine resident in the United Kingdom, with a history of travel to Austria and Germany for work reasons , which arrives asymptomatic to Argentina from Frankfurt at the end of December 2020 and in Ezeiza it is positive for SARS CoV 2 antigens “, Salvarezza reported this morning on Twitter.

The report of active surveillance of virus variants added that “the result was confirmed by laboratory PCR and the sequencing of the S gene confirmed the presence of the variant VOC202012 / 01 (United Kingdom) (lineage B.1.1.7), being the first time it is detected in the country “.

In this regard, the technical scientific director of ANLIS Malbrán, Claudia Perandones, explained to Télam that the variant of the SARS CoV2 virus from the United Kingdom, although it showed greater transmissibility, “does not aggravate the clinical picture of the disease, and that is very reassuring” , according to tests carried out in conjunction with a team from New York.

The Malbrán team is collaborating with a study by the Mount Sinai School of Medicine in New York to answer the question about what happens to the body’s immune response, in the face of this UK variation of the SARS CoV2 virus, specifically with the N501Y mutation, which has more adherence to the ACE2 receptor, where entry into the human cell is facilitated.

Although the results have not yet been published, it was confirmed that the N501Y mutation (from British variant) cannot escape neutralizing antibody-mediated immune response“, detailed Perandones regarding the American study with which Malbrán collaborates.

Experts say that the British strain can be neutralized by vaccines already in use around the world.

In this regard, he added that “this is very reassuring and explains why this British variant does not imply a greater severity in the clinical picture of the coronavirus.”

This study in which the National Administration of Laboratories and Health Institutes “Dr. Carlos Malbrán” (ANLIS) participates, will be replicated with the strain detected in Rio de Janeiro, explained the specialist.
