It’s unclear. In other reporting on this it’s been reported that several of the cases where in children who had recently tested positive for Covid, so there could be a link there, but there were just as many who didn’t test positive so it could be coincidental. Even more of them tested positive for an adenovirus, though it’s unclear if it’s a new adenovirus or variant. There’s also speculation that perhaps that due to Covid preventative measures, there are more children whose immune systems haven’t been primed the way they normally would and it’s manifesting itself this way in response to viruses that aren’t novel. But at this point it all seems to be speculation and there doesn’t seem to be any thing like a definitive answer.
