@darnell What we've got is the percentage of people who show up at a medical center and go "Doc, I'm as sick as I've ever been in my life" and the place tests and finds it is Flu A, but the Doc is suspicious and has it sequenced or they sequence it because it resulted in mortality. What we know is that a high percentage of people who show up at the ER really, really sick, do end up dying from it.
