Long covid: One in seven children may still have symptoms 15 weeks after infection, data show
A large study of children and young people who caught SARS-CoV-2 has found that as many as one in seven (14%) may still have symptoms 15 weeks later.1 However, this figure is lower than in some studies that have reported a prevalence of long covid as high as 51% in children and young people...www.bmj.com
Most studies arrive at the 7%-12% range.
One study doesn't necessarily mean it's true.

These symptoms may last up to six weeks?
Once they get to college these symptoms will be more permanent.
