Yes, as long as the virus causing the epidemic infects people. But this does not mean that new variants will appear more often or that they are more dangerous.
With more than half of the world’s population still not immune, The virus will likely continue to find people to infect and where it will continue to recur in the coming months or years. And every time this happens, a small boom can occur. These changes can help you survive, transforming into new variables.
But this does not mean that the virus will continue to evolve in the same way that it has evolved since its appearance at the end of 2019.
When a virus infects a new species, it needs to adapt to the new future to spread more widely.said Andrew Reed, a virologist at Penn State University.
According to the Centers for Disease Control and Prevention (CDC), the delta variant is twice as contagious as previous versions of the virus. Dr. Adam Loring, an expert in viruses and infectious diseases at the University of Michigan, said that while it may continue to mutate to become more contagious, it is unlikely to double its rate of transmission again.
“We have seen a rapid evolution of the phase of the virus. He has been reaping the ripe fruits, but there is no infinite amount of things he can do,” Lauring added.
The virus may become more deadly, but there is no evolutionary reason for that. People who are very sick are also less likely to come into contact and spread the virus to others.
Experts are investigating whether emerging variants might be more effective in avoiding protection that develops with vaccination and infection. Dr. Joshua Schaefer, a virologist at the Fred Hutchinson Cancer Research Center, said that as more people are vaccinated, the virus must be able to spread between people with a certain level of immunity to survive.
“The virus can adopt a mutation that makes the immune response less effective”, pointed out.
If this happens, scientists may recommend updating vaccine formulas regularly, as with influenza vaccines.
