On the other hand, the "three quarters" is probably not the number that matters, since the vast majority of Covid-19 cases are not hospitalized. Looking at CDC data (https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/burden.html https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/burd...) it seems that roughly 6% of Covid-infected people with symptomatic illness get hospitalized; so if three quarters of those will have long-lasting symptoms then it means that if you get Covid, then your likelihood of having long-lasting symptoms is something like 4.5%. On the other hand, while that risk is not that widespread, that still will mean millions of affected people.
