No but the feds control international commerce and travel. Therefore I agree that anything on the scale of a potential pandemic is in the realm of the feds. You think for one second the differing viewpoints of various states could coordinate a unified and exact set of rules with respect to containing a potential pandemic? Good luck on that. Let me know how that exactly works out between the state’s of California and Texas
The States do just fine with health on every issue. This will be no different.
Once they get to the States, the potential diseased people need to deal with the States, not the Feds.
And the Feds haven't done a bang-up job of it, if you haven't noticed.
