The doctor told me that it is now dominant omicron strain subtraction BA.4 and BA.5.
“Of all the strains of the coronavirus, they are known to spread the fastest and have the greatest resistance to the immune response of antibodies.
Even neutralizing antibodies, formed after infection with the first strain of omicron strain, are 3-4 times less able to neutralize BA.4 and BA.5. This means that the resistance is higher in this case,” explained Dr. M. Strioga.
Another sign, according to the interviewer, is that these omicron subspecies are not seasonal: “These waves are seen in different countries of the world, including the South, even in summer. The seasonality was also less pronounced for common cold viruses and earlier strains of the coronavirus, but many strains are still suppressed during the summer.
This is not typical for these. But the most severe course of the disease (despite the results with experimental animals that seemed to show that these subtypes – BA.4 and BA.5 – seem to be more prone to damage the lungs) was not observed in practice clinic, especially in the country where this wave happened, that is to say in Portugal. They haven’t even kept up with the number of hospitalizations and deaths they had over the winter with the wave of the BA.1 omicron strain.”
Professor Vytautas Kasiulevičius in the “Persona grata” program of “Žinių radio” observed that waves last longer in Eastern Europe than in other parts of the continent.
“Our waves are a bit longer: they rise longer than in Western Europe and last longer, then they fall longer. This is determined by certain types of people’s behavior and so on,” V. Kasiulevičius said on the show. You can read the whole text Here.
When asked why the waves last longer in Eastern Europe, Dr. Strioga said that the reasons could be diverse: “Many factors can play a role in this, both the level of vaccination and adherence to various measures to stop the spread air infections are recommended.
In the Scandinavian countries – Sweden, Norway – Governments did not introduce strict restrictions or announce mandatory quarantine, even in the presence of strong waves of old tensions. But the people there, if there is a recommendation, without even saying that it is mandatory, they follow it. In our country, even if you say that the government has already been forced to take such measures, people will comply, but they will try to avoid it as much as possible and where possible.
Even in the South, this is not the case. Even Italians, Spaniards, Portuguese were disciplined. I saw it with my own eyes when I was in Madeira.”
When asked what will happen next and if we are at risk of a “bad” strain or the strain of the strain of COVID-19, the interviewer replied that it is difficult to predict, but there is no high probability that some radical strain will appear.
“From the point of view of spread, this virus has already acquired enough properties. It is already very widespread and contagious. In general, BA.4 and BA.5 probably align with measles in terms of prevalence.
For a new strain to become dominant, it must have some sort of evolutionary advantage over existing strains. These are the laws of evolution: if you do not have some advantage, you will not take the place of someone superior to you.
If a virus were to mutate to cause serious disease, societies would put restrictions in place to prevent the virus from spreading. Quarantine would be introduced, other measures would be applied, and this characteristic would become favorable for the virus from an evolutionary point of view, and this would stop its spread.
French virologists believe that the strain or substrain that has an advantage in all respects over the existing strains begins to dominate. And what do we see? This in fact the strains are moving in the direction of greater infection, but less danger “, said M. Strioga.
The doctor did not even doubt – one way or another we will all definitely face micron, the only question is when.
“As long as this collision does not cause a heavy burden on health care, then the restrictive measures are not indicated. And the vaccination is necessary now to avoid the worst consequences.
There was an interesting review article in the New York Times that this coronavirus infection, COVID-19, will take root and become one of our companions.
He even said that the infection could even enter the top ten diseases with the highest mortality rate. It may be so.
How big this rate will be and how many infections and deaths will depend on how many people take protective measures, the main of which is immunoprophylaxis – vaccination.
But there is such a possibility that this virus will become our companion and we will not be happier that we will have to live with it. We estimate that maybe 0.03 percent will die from it in the US. people,” said the doctor.
