Doesn’t the IFR depend on things like age structure of a population? Availability of appropriate medical facilities and capabilities (care, testing, etc)?
Take Iceland: per WHO, 1836 “confirmed cases”, 10 deaths. If “90% of cases” were not counted, but 100% of the deaths were, then the IFR would be 0.05% (10/18360).
