> That's not the system in the US - or hasn't been. The Federal government maintains what, until recently, was the world's premier infectious disease-fighting organization - the CDC. The implication was that pandemic response occurs through this organization. In the past, this is exactly what happened.
While you're right that the Federal government has the CDC, every single US States has its own infectious disease/health agency[1]. Furthermore, the EU also has its own centralized disease agency[2]. Structurally, both the US and EU are very similar in this regard. The only key difference is that (to your point) the EU States may override the ECDC, whereas US States may not — certainly a worthwhile policy change for the US.
> So the idea that this pandemic response is up to the states doesn't hold water. Had the states known that they'd be left twisting in the wind, they could have taken steps beforehand.
But this is factually incorrect, States did take steps beforehand. By March 23, every single State declared a state of emergency, and 48/50 States closed their schools. By as early as March 9th, the States were doing the VAST majority of COVID testing[3]. As of right now, the US has administered more tests per capita than Belgium, Australia, Ireland, Italy, New Zealand, Canada, Switzerland, Germany, Austria, Norway, and Sweden (to name a handful). This is not because the US has a nationwide testing regime, rather it is because testing systems have been administered at the State level[4].
