We understand how the flu behaves. We've had >100 years of flus and Spanish Flu only happened once. The only experience we have with poxes in humans is smallpox and monkeypox. Smallpox was not a good time. Past monkeypox outbreaks have killed 5%. This one is behaving very differently, but we don't know if it's going to revert to killing people! It has in the past, like every outbreak, so it's a rational worry.
