I’m glad I read the book about the 1918 pandemic last year, because I understand something that most people should and don’t. Mutations aren’t necessarily bad, in fact over time the mutations will make the virus less deadly. It’s all about evolution and survival of the fittest. Mutation is how evolution happens. A new variant shows up and if it is in some way more likely to propagate and survive than previous variants, it will stick around and thrive, and continue to mutate. If a virus kills its host — that’s not good for survivability. So what happens over time, a virus like Covid becomes less harmful and more transmissible, that’s how it becomes “the flu.” The 1918 influenza virus is still with us today. But it doesn’t kill people in the numbers that it did a hundred years ago. Over time Covid will get less deadly too.
