More than one individual predicted a virus that would devastate the human race. It's just that people didn't quite predict how. Maybe it was the over exposure. Society got bored with viruses and complacent with a potential new threat on the tail of Covid-19.

Something mutated the virus past what anyone could have expected and it was far too late to hope that isolation would prevent the spread. Not when those infected starting hunting those who weren't...

If there is anywhere safe left in the world.
