What do we know about new forms of coronavirus ?
This has led to strict restrictions on gatherings for Christmas celebrations in many countries, including the UK, Scotland, and Wales. Fourth-degree restrictions mean that people will not be able to interact with anyone outside their home without their family members. Many European countries have also banned flights from the UK to curb the growing number of new cases of the corona.
How did the virus change from a non-existent form to a normal one in a few months in the UK? Government advisers have little faith in the new infection, saying it could affect more people than any other form of the virus. The whole thing is still in its infancy, full of uncertainties and a long list of unanswered questions. As I wrote earlier, the tendency of viruses is to change all the time and we have to be very careful about whether the tendency of the virus is changing.
Three things are happening together that make it interesting: It is changing faster than other forms of the virus.• There are changes and the part of the virus that is affected may be significant. Many of these changes have already been shown in the laboratory to increase the virus's ability to infect cells. The three work together to create a virus that can spread easily.
However, we do not have a solid truth. New forms can also become more common when they are in the right place at the right time. As happened in the UK where there were still only second-tier restrictions.
But already fourth-degree restrictions are meant to prevent the spread of the new form.
How fast is it spreading?
The first case came in September. One-fourth of all cases reported in London in November where new forms of coronavirus. It reached about two-thirds by mid-December.
You can see from the tests done in many centers like Milton Keynes Lighthouse Laboratory how the new form of the virus dominated the results. Mathematicians are estimating the number of cases affected by different forms of the virus to determine how many cases there may be. But it is difficult to know whether it is due to human behavior or a virus. According to figures released by Prime Minister Boris Johnson, the new look could spread 70 percent more. He said it could rise to the R-number - indicating that the epidemic is increasing or decreasing at a rate of 0.4. On Friday, Imperial College, London's Dr. In a presentation by Eric Walls, the figure was 70 percent. So there are no clear statistics on how much more virulent the virus can be. Scientists whose work has not yet been made public told me that the figures are much lower than 70 percent. But the question remains whether it is more capable of infecting.
Professor Jonathan Ball, a virologist at the University of Nottingham, says: "Evidence from the public about whether the virus has really increased the risk of infection is insufficient to form any solid or clear opinion."
What do we know about the new version?
Preliminary studies of the new form have been published and 17 potentially significant changes have been identified. Changes have been observed in spike proteins, the way in which the virus enters the body's cells.
A change called N501 changes the most important part of the spike called the "receptor binding domain"Another mutation is the deletion of H69 / V70, in which a small part of the spike is removed. It has been born many times before, including the famous mink infection.
A study by Professor Ravi Gupta at the University of Cambridge shows that mutations in the form of the virus appear to be more than double the number of infections in laboratory experiments. Studies by the same group show that deletion makes the immune system in the body of survivors less effective."It's growing very fast, that's what worries the government, most scientists are worried," Professor Gupta told me.
Where did it come from?
This form is abnormally variable.It may be that the form developed in a patient whose immune system was so weak that he or she
Will it make the infection more deadly?
There is no evidence that it will, although it needs to be monitored. However, the growing number of cases is enough to create problems for hospitals. If the new form means more people will be infected more quickly, it will create a need for hospitalization for most people.

Definitely yes or at least for now. The spikes in the three major vaccines, in turn, develop the immune system to react, which is why this question arose. The vaccine teaches the immune system to attack different parts of the virus, so the vaccine will work even if part of the tax spike is changed." But if we let it change, you start worrying," says Professor Gupta."The virus is probably on the way to a vaccine avoidance, it has taken the first few steps towards it."
Vaccine prevention is possible when the virus changes to such an extent that it continues to infect people by eliminating the effect of the vaccine. Perhaps the most worrying thing is knowing what is going on with the virus. This new look only shows that the virus is constantly adapting as it is affecting more and more people. A presentation shared by University of Glasgow professor David Robertson on Friday concluded, "The virus may be able to develop the form needed to avoid the vaccine."This will put us in a situation similar to the flu, in which the vaccine needs to be updated regularly. Fortunately, it is easy to change the vaccines we have.
