This sort of foolishness is what can seriously impact the nation's and world's economies (already happening). Every disease has the potential to be fatal, from an infected scratch on your hand to the common cold. We don't know the death rate because nobody knows the actual number of cases; to know that, everybody would need to be tested, and we are nowhere near able or willing to do that. And as I posted previously, and is true to date as far as anyone knows, children don't die from this (or if they do it is rarely, and there are no reported deaths yet), and healthy young (under about 40, perhaps 50 y.o.) adults very very rarely die from this. Excluding China, the overall death rate is about 1.4%, and less than 1% in most countries, and that latter rate is what the CDC and WHO are predicting when more complete data is available
