There are 64 potential cases of children in New York with a mysterious inflammatory disease associated with COVID-19, state Department of Health Commissioner Howard Zucker said Wednesday.

State health officials released an advisory on the condition Wednesday in order to provide guidance for testing and reporting. Health care providers, including hospitals, are required to report any cases of inflammatory syndrome in children to the state Department of Health.

“Thankfully, most children with COVID-19 only experience mild symptoms, but in some, a dangerous inflammatory syndrome can develop,” Zucker said. “While we continue to reduce cases through social distancing, discoveries like this remind us we are still in the middle of our response to this deadly pandemic.”

A possible link to COVID-19, believed to be especially dangerous for older adults, was first reported in the United Kingdom to the separate illness in children.
