Also the children I’ve met with suspected PIMS -TS weren’t children with additional health needs. They were healthy children who developed symptoms post covid. (antibodies can be checked)
It has been a small number that have either been treated in a normal ward or needed higher level care. It’s something to have an awareness of but it’s not happening in large scale numbers.
But the more children that catch covid, even mild asymptomatic infections you suggest more could go on to develop post viral symptoms.
Covid is still a new condition we are learning about the post infection developments and medics don’t know what variants will do:if anything different or nothing at all. Which is why we still should remain cautious.
