Could this child syndrome have a link to COVID-19?

Can we find any research that shows evidence?

It’s a new disease that we think may be caused by the COVID-19 virus — we’re not 100% sure because some of the people who got it hadn’t tested positive, so we’re doing a lot of research now but it is something we’re worried about. Although it is very significant for those children who do get it, the number of cases is small.”

He also says: It’s an absolutely tiny number! I think the number of infected children is tiny anyway.

    Wikipedia answers your question. And since Kawasaki disease was identified almost 60 years before the SARS-CoV-2 virus even existed, I think we can safely say there's no connection. – Carey Gregory May 1 '20 at 0:05
  • Some other coronaviruses have been linked to Kawasaki Disease. – Graham Chiu May 1 '20 at 4:06
  • @Carey: Kawasaki disease can be diagnosed only clinically (i.e., by medical signs and symptoms). No specific laboratory test exists for this condition. This wiki has been written before the SARS-2 virus could have been tested. My question is pointing whether it has to be rewritten. – Albrecht Hügli May 1 '20 at 4:59
  • My point is that your question demonstrates zero prior research. If I can google your question and find an answer immediately, then your question needs work. This is a poor question. – Carey Gregory May 1 '20 at 5:12
  • The CNBC report linked states that the new inflammatory disease is likened to Kawasaki disease and sepsis, not that it is Kawasaki disease or sepsis. – Chris Rogers May 16 '20 at 9:04

The causes of Kawasaki disease/syndrome are not well understood.

Kawasaki involves inflammation of blood vessels, and is rare but almost exclusively found in young children.

There are media reports of associations of Kawasaki and COVID-19 but these are fairly early reports and it is unlikely (and I am unaware of any) that there are any sufficiently large samples of cases that have been organized to suggest a true causal role: these alerts are best directed towards physicians to be aware of the possibility when examining patients rather than to the general public.

  • There have also been reports of some kind of [rare] inflammatory reaction to Covid-19 in children. I have no idea if they could be related but Kawasaki's disease has been mentioned in such contexts/discussion. cnbc.com/2020/04/28/… (I see you CNN link is actually about the same thing, i.e. the alert from the England NHS on children with this presentation.) – Fizz Apr 30 '20 at 23:19

    @Fizz - the CNBC report you linked states that the new inflammatory disease is likened to Kawasaki disease and sepsis, not that it is Kawasaki disease or sepsis. – Chris Rogers May 16 '20 at 9:03
