Is discovery of South African Covid-19 variant in India a matter of concern? | South African Strain
Rospotrebnadzor discovered the South African strain coronavirusarusia was subjected to a viral attack from South Africa, about the discovery of a new strain of the coronavirus of the South Africa reported at the end of last year. As South African scientists installed, the mutation turned out to be about 50% of the contagious. In the National Laboratory Health Service, Johannesburg warned that the new strain could be dangerous by the risk of re-infection, and the developed vaccines may be ineffective. In February, an increased contrast of mutation from South Africa confirmed the World Health Organization (WHO).
The Institute of Molecular Genetics Institute of Molecular Genetics, Russian Academy of Sciences Konstantin Severinov has no doubt that the South African strain, like a large number of other COVID-19 options, in our country “has existed for a long time”.
Microbiologist explained to “Findfairfaxandloudounhomes.com” that numerous strains, although they are geographical names, “actually spread throughout the world.”.
“In addition to the initial, so-called reference version of the coronavirus, which was first allocated in Uhana, the world was distributed quite a large number of other versions of the Wuhan strain,” said Konstantin Severinov.- Amazingly these modified viruses arose in several countries and, apparently, independently of each other. British, Brazilian, South African and many other strains have approximately 20 differences from the original virus. All these variations arose, apparently, on the same scheme – as a result of competition between viruses affecting the same person “.
The microbiologist explained that “some people are experiencing COVID-19 not so acute and not asymptomatic, but just for a very long time they hurt. As a rule, these are people with reduced immune status: viruses in them, as in the flasks, competing with each other, slowly acquire a set of mutations. These mutations change certain areas of the S-protein, as a result of which such viruses are able to better interact with human cells, that is, they are more infectious. “. Mr. Severinov does not exclude more severe pathogenicity (sickness) of some strains, including South African. It expects an increase in the proportion of such modified and “more efficient” viruses with time, calling this process “Typical Darwinian Evolution”.
What difficulties encountered campaigns vaccinations from coronavirus
The detection of the South African strain of coronavirus in Russia, Konstantin Severinov, is rapidly with chance. “It is necessary to highlight the virus from the patient, and then determine the sequence of approximately 30 thousand. "letters" RNA virus, – explained the microbiologist.- To do this, you need to possess the appropriate skills and technologies that are poorly developed in Russia. To date, more than 400 thousand were obtained in the world. Full-hegeneous sequences of coronavirus isolated from individuals. Of these, several thousand are made in Russia, and this is very little. We use a fairly simple reaction test, which says there is a virus or not, and what – we do not know, our tests do not give such information. Most likely, they took two random patients, determined the sequence of the genome of the virus, which they had, and found out that it was similar to the South African strain “.
Konstantin Severinov added that a very small proportion of the population was vaccinated in Russia. “Such variants of the virus truly weaken the effect of the vaccine, but not so much to prevent their protective action,” he believes.
Vaccinologist, Chief Physician of the Medical Center “Leader-Medicine” Evgeny Timakov believes that the new coronavirus strain was discovered due to the “clearer monitoring and more surveys conducted”.
Mr. Timakov confirmed “Findfairfaxandloudounhomes.com” that the South African strain, as, however, and the British, is able to “transfer to a person faster”.
“In Russia, a rather large number of people susceptible to coronavirus infection remained, respectively, if we have a massively multiplinary virus, you should expect a sharp jump in the incidence, – Evgeny Timakov said.- Therefore, the anti-epidemic regime should be maintained, it is impossible to cancel mask mode, and vaccination should be actively carried out, so we will be ready for the strains will come. And they still come to us, we want it or not. “.
The vaccineologist added that people who were vaccinated from COVID-19 so far there is nothing to fear: “Our domestic vaccines work against all the coronavirus mutations that are now proven by experiments on the abilities of human antibodies in the blood plasma to neutralize this coronavirus.
According to the deputy director of the St. Petersburg Research Institute of Epidemiology and Microbiology named after Pasteur Alexander Semenov, “the principal differences from the South African strain known for those known earlier in terms of forecasting, therapy and prevention does not have”. “We are monitored by all strains, we have already studied its properties and can quite responsibly say that the developed diagnostic tools allow it to identify it,” Alexander Semenov said.- Now they put experiments on neutralization tests at the graft and passing – there are no features, emergency options, which would make us alert more than before the identification of this strain. We are ready to define it, and treat them infected people “.
According to a scientist, you can be calm about the fact that the projacination Russian citizens are protected from the South African strain “no less and no more than from British, South American and others”.
At the same time, Alexander Semenov warned that all new coronavirus strains periodically appear: “This is a natural process of coexistence of a person and a parasite, which suggests that the population of people will try to form antibodies, and the population of viruses – trying to break through immune protection and infect as many people as possible What we are ready “.
