“It just came to our attention then. The virus is one and it may have mutants. This mutant in question in Great Britain is known in Europe and South America. It has existed in our country since June. There has been a publication about its existence since the end of March. You may be in Britain soon. ”This was declared on the air of” Hello, Bulgaria “in NOVA by virologist Prof. Radka Argirova.
He added that in addition to this mutant of the virus, there are another 4-5 species. They had a much lower prevalence, up to 3%.
“Most importantly, none of these mutants will change the reaction to any of the vaccines on the market against COVID-19,” said Professor Argirova.

According to her, if a person is infected with the new mutant of the virus, the incubation period is lengthened.
“We have the following observations, from the hospital itself. First, rejuvenate the patients, and the young get sick. Second, the incubation period seems to be longer. Previously, we observed the first signs 8-9 days after the first Symptoms Now this seems to happen in 12-13 days, and a little later the cytokine storm comes.
Prof. Argirova: 13 thousand covid-virus mutations have been described
“Our doctors have long understood that the virus is not the same. I have said many times that initially the circulating Wuhan virus no longer exists and now it is completely its mutants,” said Professor Argirova.
“There is no reason to worry. Everything works. The tests work perfectly. And the Minister of Health said they had checked everything. I think it made a little more noise, but this is beyond my competence as a virologist,” he explained Prof. Argirova.
He reported that yesterday around 100 PCRs and around 120 antigen tests were performed in the laboratory where he works.
Virologist: COVID-19 mutates, spreads more easily
“Hopefully the antigen tests that are bought across the country are sensitive enough, over 90%, so they can really replace PCR tests.”
“I am categorically against this and there is absolute evidence that this was created and launched in Wuhan,” said Professor Argirova.
He noted that 90 different coronaviruses had been isolated from bats. Among them is SARS-CoV-2.
“Now it is considered at this time that this is the natural reservoir, but from there there will probably be a hospitable interlude to enter the town and to the extent that such is a” accused “battleship. The virus isolated from this armadillo matches perfectly in the most important area to bind to the human AC2 receptor: 5 of the 6 amino acids coincide at this site. However, there is a part of the structure of S, the protein in the virus’s peak, that is not present in the armadillo or the bat, but is present in human SARS-CoV-2. It is assumed that it took an evolutionary time, several years, to develop this part “, explained Professor Argirova.
The virologist recommended the vaccine to the German company Biontek. “It is exactly the part of glycoprotein S that binds best to the human receptor. This is the most specific place in the virus, against which, if we form antibodies, they will be really effective. No matter how many mutations occur in the future, this place is not will be affected.
“More young people are already involved in the infection and disease process. Security measures are still being ignored everywhere. Now I am very concerned about the gatherings at Christmas and New Year”, commented Professor Argirova why Bulgaria ranks second in the world in mortality from covid-19 as a percentage of deaths in the last two weeks.
