You can ballpark it based on similar viruses, long covid is CFS/ME/Dysautonomia which is known to occur after harsh viruses at a rate of around 10-20%. It's knowable in research but doctors and public institutions are very slow to pick it up. Just look at how little was done with CFS/ME and how much medical gaslighting is still going on even though very clear diagnostic tools now exist.
