population pyramids
This is a diagram of the population pyramids of India and Russia, where the coronaviruses are converging. (India on the left, Russia on the right)
Europe seems to have a large number of people whose immune systems are generally declining.
I think this is one of the reasons why the infection has not been contained.
The reason why I am looking at Russia is because I want to know if the virus will cause an error catastrophe and converge in countries with this age structure and low vaccination rates.
If there is a sharp decline within the year, I believe the battle on the Eastern Front will be over.
And the same goes for the Western Front.
As a result, I think COVID-19 will become a passing content.
(These were my thoughts before the advent of Omicron.)
