What now? How pandemics end

> Unfortunately, viruses don’t change to become less severe. It’s true that Omicron is less severe than Delta. And, it’s an obviously attractive scenario if this virus continues to mutate to be less and less severe. But it’s not guaranteed. That’s because mutations are random.

Nope. See Cholera that spreads via contaminated water supply versus Cholera that spreads person to person. Given random mutations, natural selection and emergent pressures take hold. That so many people who ostensibly believe in evolution don't actually understand the mechanisms of it is a continuing personal frustration of mine.
