With this caveat...

Long COVID is neither well-defined nor well understood, in part because the research base is still in its infancy. The term “long hauler” is broadly used to characterize individuals whose symptoms persist or develop outside the initial viral infection, but the duration and pathogenesis are unknown. Late sequelae have been described even in young, healthy people who had mild initial infection. And symptoms are often described by long haulers as being relapsing and remitting in nature—they improve, only to be struck back down again.

They referenced the following study...

One of the largest surveys so far, the King’s College London study, had four million users in the U.K. enter their ongoing symptoms on a smartphone app. The researchers reported that around 10 percent of patients had persistent symptoms for one month, with 1.5 to 2 percent having sustained symptoms at three months. As Hendrich suggests, this idea of “how many” is a moving target that will require more study and analysis.
