That's true. We would have a better understanding of incubation time and contagious time, and symptom rate. And the CDC would have been able to resolve that information with time to get it to us before it hit the US, and so we would better know how to handle it as citizens. The only way China would have not wanted the CDC in is if they wanted us to be blind when it hit us because they were hoping it would spread easily here because of our lack of information in the crucial beginning. This is a weapon. China unleashed it on themselves for plausible deniability.
