It's worth pointing out that the %'s are very guesswork-y and vary considerably between reporting institution, so hanging on single % changes is not particularly meaningful (apparently people were accusing my governor of conspiracy theory-esque minimizing the threat because he quoted a lower %, but it was simply from a different source). These are also likely to be higher than the actual mortality rate, because people who are mildly or non-symptomatic account for the bulk of cases yet rarely make it into the statistics at all.
They are valuable in a comparative sense because other illnesses are measured the same way, with the same flaws, and these %s are an order of magnitude higher than typical flu mortality.
