Viruses evolve, which is why we get new ones all the time.

But they can only spread if people spread them. They can’t travel by themselves. Had everyone worn masks, gotten vaccinated, and stayed apart, the virus would have died on its own. Instead, the refusal of people to take even the simplest precautions only helped it grow and mutate.

It’s very easy to see who to blame for this. And my sympathy for those who are stubborn and refuse to take care of themselves and others is waning daily.
