And do you remember recently there was such a covid

And do you remember recently there was such a covid, everyone sat at home, closed the borders and did not shake hands when they met?

The question of where the epidemic has gone gnaws at the most inquisitive minds of mankind. Less than half of the population is vaccinated, judging by the posts here, people occasionally continue to get sick, but they treat it as seasonal flu: well covid and covid.

Has the virus run out of batteries? Has humanity’s immune system adapted? Covid was man-made and they shut down its source?
