> Has there ever been an influenza/coronavirus-like infection with less than 0.1% fatality rate in working-age people (https://www.worldometers.info/coronavirus/country/singapore/ https://www.worldometers.info/coronavirus/country/singapore/) that caused lasting disability in a significant proportion of the population? I've read that the low fatality rate of Singapore is due to mostly foreign, younger, healthy workers being the "cases" who were infected. Assuming that, the statistics of Singapore is not in any way inconsistent with what is observed in other locations. We already know that the older people have an order of magnitude higher probabilities to die while infected, or even two orders of magnitude when old enough. Note that the "fatality rate" in this context then says absolutely nothing about the permanent damages of the people's organs. The fatality rate is just "who promptly died after being detected positive." We don't know how many of Singapore cases remained with worse health after being infected, or even if some died or will die later, after being declared virus-free, and it's not probable that we'll know, them being the foreign workers. Therefore, it seems that citing Singapore in this way is irrelevant while talking about the known and reported cases of people with damaged health in, for example, the U.S. We need other statistics.
