The symptoms they had during the acute infection may not go away, even long after their infection is gone. What experts do know is that long-haul COVID can happen even in people who had mild or no symptoms of COVID-19. Office for National Statistics estimated that 12.9% of children 2 to 11 years of age, and 14.5% of children 12 to 16 years old, still experienced symptoms 5 weeks after infection. One study showed that as many as 52% of teens and young adults between ages 16 and 30 may experience lingering symptoms 6 months after having COVID.

No one is certain exactly how many people who've had COVID-19 end up being long haulers. Most notable are continued or recurring symptoms referred to as "long-haul COVID," or sometimes as "long COVID" or "Post-Acute COVID-19." Research on this condition continues. Post-COVID conditions have been identified in kids. But it has become clear that some are experiencing symptoms more than a month after they've been infected with SARS-CoV-2, the virus that causes COVID-19.

Most kids and teens who test positive for COVID-19 have mild, or even no, symptoms.
