Вирусолог Анатолий Альтштейн оценил перспективы формировании в России коллективного иммунитета. Все что нужно знать о коронавирусе Covid-19 и его тестах.
Новый тест на Covid-19 имеет скорее научное значение
A test system has been developed in Russia for the diagnosis of the British strain of Sars-Cov-2, which is transmitted faster from person to person. The express test is now being tested, new technology allows analysis in just 1,5 o'clock, while, as for a classic test, three times as long is needed.
That is unnecessary. The new test has more scientific significance, we need to find out how widespread this British virus is.
An ordinary test is sufficient for diagnosis., which we already had. Правда, I must admit, that it gives false negative results quite often, while, как клиника
Treatment tactics depend on the severity of the disease, not from the strain. No data, that people infected with different variants of Sars-Cov-2 need to be treated differently.
It is necessary to focus on the human condition, to control, what happens to his lungs and other organs and, depending on this, build treatment.
Yes, while we think so. No data yet, who say, that this vaccine might not work against some strains of the virus.
Today we believe, that there is one serotype of this virus and any vaccine works against it, which are now produced. But this question, of course, will need further study too.
There are general patterns. Постепенно эволюция вируса идет в сторону большей заразности при снижении его патогенности – то есть уменьшения летальности. Cannot be said, that this is happening at a fast pace. But we see clearly, that in the spring many more people died from covid, than now.
This is not only due to the change in the virus, but also with the improvement of treatment methods. But, honestly, they have not improved that much, to explain this big difference. World average more died in spring 5 percent of patients from identified cases. Now the mortality rate is somewhere in the area 2 percent.
Vaccination has a twofold meaning. The first point is, that the vaccinated person himself will be largely protected from infection.
Immunity is formed later 42 days after the first shot of the two-part vaccine and the likelihood that, that the vaccinated person will become infected and die is reduced to 10 time. The second and very important side of vaccination is the creation of herd immunity.
To obtain herd immunity, at least half of the population must be vaccinated. Those vaccinations that are now being carried out, they will also have a certain value, но небольшое – они снизят заболеваемость на 5-10 percent.
And only when this process becomes universal will it be possible to talk about herd immunity. But I'm afraid, that this is still very far.
