After analyzing more than 166,000 complete SARS-CoV-2 genomes, Professors Antonio Salas and Federico Martinón of the University of Santiago de Compostela concluded that it is a great simplification to blame the strain on “the chaos we are experiencing” .
The role of Super infected Santiago de Compostela University professor believes that the “perfect catalyst” for the pandemic caused by covid-19 seems to have been proven Antonio Salas ÿ Federico Martinón on Works published in January magazine science, And other researchers have not yet reviewed this.
After analyzing more than 166,000 complete coronavirus genomes, the scientists said: “Having the strains that cause the chaos we experience is a great simplification of the pandemic algorithm.”
According to their estimates, the super-infected person is still the “engine” of the current health crisis, and whatever the situation causes, it may lead to a large-scale outbreak. tension SARS-CoV-2 dominates.
The team led by Salas and Martinón decided to explore the super-contagion model in a database much larger than the one used in the database. Published works Published by these authors in May 2020.
In this work, scientists have solved hundreds of events that have occurred throughout the world in the pandemic.By exploring thousands of Viral genome, They managed to confirm that a large part of the infection was explained by the super infection. Salas said: “It is gratifying to see increasingly consistent evidence of the importance of hyperinfection in the spread of the virus.”
magazine science It has recently been reported on Boston In the first wave. “A few months ago we had reported on two Boston incidents and dozens of incidents. We were unable to detect another incident because we could not obtain these shots. Now, we have access to a larger database and Using the exact same method as in May, we did detect this database, even hundreds,” he continued.
Strains and vaccines
As far as Professor Martin Martin is concerned, he emphasized the importance of “monitoring strains spreading around the world, because it can remind us of the need to develop preventive measures and redirect them when necessary. vaccine Existing and upcoming. It is relatively easy to update vaccines with emerging new variants.
“When it is said that one strain is more spread than another, it is important to put this statement in context.”
According to scientists from the Institute of Health Research (IDIS), the emergence of new virus strains in humans is nothing special. SARS-CoV-2. “Knowing the dynamics of the virus helps them to include strains such as the United Kingdom, Brazil, or Japan. When it is said that one type of pressure is more spread than another, it is important to put this statement in context and Don’t forget that the means of communication and social behavior are two powerful driving forces of communication. PandemicExplain Salas.
Generally speaking, whether it is a carrier of a variant, a person wearing a mask and maintaining social distancing can prevent infection. On the other hand, super infectious agents are ideal catalysts that can cause large-scale outbreaks, thereby turning mutations that occur in a single individual into major mutations.
Primary or secondary valuation Infectious ability Scientists say that the isolation of strains should always be carried out under relative conditions. “The infectivity of strains is always studied in a specific geographic space and compared with other variants that are spread in the same epidemiological context. However, Salas explained that it is not for all those circulating in the world. Or extinct, and at some point also a dominant species.
For the professor at the University of Southern California, “Holding the strain to account for the chaos we are experiencing is a great simplification of the epidemic algorithm, although it is an effective way to prove the reasons we cannot control at the social level. According to current data, the so-called The new strains of serovar are not popular in Spain or rarely appear in December, so it seems reasonable to think that “Let’s save Christmas” may be the trigger of the third wave.
A few months after the pandemic began, Salas and Martin Long’s team released the first results of their research on the SARS-CoV-2 genome. In this first work, Genome Research, The researchers studied all aspects related to the origin of the virus, starting from the leap of zoonotic diseases, and abandoned artificially created viruses in the laboratory. They also analyzed patterns of genomic variability on a global scale, System tree The isolation of SARS-CoV-2 and the distribution of its strains worldwide.
“The so-called new strains are not circulating in Spain, or rarely appear in December, so it seems reasonable to think that’Let’s save Christmas’ may be the trigger of the third wave.”
However, one of the most unpredictable results of the group is that it prompted these authors to propose a super-infectious model in the spread of infectious diseases. virus. This work is groundbreaking on an international scale, and its results become more and more important with the passage of time. Therefore, such as science ÿ natural Agree with this proposal of the Galician group.
In the author’s follow-up article, they used the same analysis model to study Pandemic mode The role of the Spanish virus genome in its first wave of expansion. There, they were able to observe that almost all cases in the state were caused by five strains, especially two of them accounted for almost 70% of all infections in the database (B3a and A2a5).
At that time, the mutations that caused B3a and A2a5 were absolutely dominant in the country.
