And dropping the "after recovery" goes astray from the central point of the article. That we are mistaken when we think that people have recovered.
should work; it's easy to infer that "after a year" refers to their hospitalisation anyway. If that is still too long: "Less than 20% hospitalised COVID patients symptom free after a year"

It seems like the primary theory is that the virus is still in the body even when tests are negative.
And that the virus causes all kinds of immune responses which cause the symptoms.
But considering how much the chance of hospitalisation is reduced, that'll probably still be the same today.
COVID has been terribly explained in the media, and emphasis now should be on how it is for way too many a chronic disease that people should avoid at all costs, a disease currently with no cure or treatment, which can turn you into a disabled person in the worst cases.
