How likely are these numbers to be accurate? This Swiss study of 431 adults gives a 26% incidence of "Long Covid" at 6-8 months.
But another study that I'm more familiar with that tracked 4,182 people (mostly from the U.K., U.S., and Sweden) says only 2.3% of participants reported symptoms past the three month point. [0]
I feel like every time I look into this topic I find a new study with a wildly different estimate.
