You're comparing the Trump and Obama administrations handling of different diseases and it looks like you are making a partisan point.
This is the early phase of a crisis. Now is the time to call on leaders to do things; not to politic about whether something could have happened a bit earlier or not. Trump is still going to be held responsible for the administration's performance; but now isn't the time.
Nobody is going to bother going back to compare this to the Obama Administration's H1N1 response. The H1N1 response is not a useful guide for how to deal with the piles of dead bodies that are about to start appearing outside hospitals.
