IFR is a really important peice of information as it effects the overall management of outbreak. consider these scenarios: A) IFR is really low and most people dont seen anything past slight discomfort, so given the number of 'cases' being treated now it would mean a much larger portion of populus is already infected. translation we can reach herd immunity faster & more safely. B) IFR is high (closer to CFR), which means the current case count is more or less in line with actual infected people. which means we really need to focus on lockdown and slow the growth so we can manage the hospital capacity. as you can see both of these scenarios have different optimal responses but we cannot decide unless we get this info. so far we only have a few biased sample sets (from us pov) diamond cruise & skorea which dont shed much light on our situation.
