Our president's an idiot who doesn't what he's doing, surrounded by sycophants who feed his ego even as he says and tweets insane things that lead to the impression that we're going to beat this in a matter of weeks, so people are not taking it as seriously as they should. There's that on the government side. And on the larger society side, because so many are not taking it seriously, it is spreading very quickly from asymptomatic people to people like me (went out to get groceries yesterday; came home with groceries and a fever). And I've been self-quarantining as best as I can, and wearing a mask when I go out, etc.
This is a perfect storm of stupidity. We're going to pass China in no time, assuming we haven't already (most people are not getting tested, so we have no real way to know the true numbers).
