“As a virus mutates, it becomes more contagious and less lethal. And then eventually it mostly disappears. Many voices claim that Delta will be with us for a very long time, but we should be so lucky. It’s way more likely that it will soon be followed by a next variant that will in turn become dominant. And more contagious and less lethal.”

A good read for a sense of perspective.  Recommended.
