At least 73 children have been diagnosed with symptoms similar to Kawasaki disease — a rare inflammatory condition that often impacts children aged five years or younger — and toxic shock syndrome, and it could be related to Covid-19.

New York governor Andrew Cuomo announced a five-year-old boy died in a New York City hospital on Thursday after health officials said they initially believed children would be largely unaffected by the coronavirus.

“While rare, we are seeing some cases where children affected with the Covid virus can become ill with symptoms similar to the Kawasaki disease or toxic shock-like syndrome that literally causes inflammation in their blood vessels,” Mr Cuomo said during his Friday press briefing.
