He may never admit it; but he seems to have learned too that he can't control a virus by words alone and denying there's a problem. I think he knows if he keeps denying things, he'll be in a worse spot politically so lying would hurt him not help. That too is a good thing since it would show he learned from his mistakes. Who''s perfect? I don't ask anyone to be perfect; but it is great when people learn from their mistakes.
One can hope. Let's see if he manages to change his behavior. I don't think he can control it.
