Gov. Andrew Cuomo said Saturday that three young children in New York have died after being hospitalized with a rare and mysterious COVID-19 related illness.

One of the deaths was a 5-year-old boy on Thursday.

At his daily coronavirus briefing in Manhattan, Cuomo said the news was “disturbing.”

“This is the last thing we need at this time,” he said.

New York hospitals have reported 73 cases involving children experiencing symptoms similar to Kawasaki disease and toxic shock-like syndrome possibly due to COVID-19.

Cuomo said the illness has been found mostly in toddlers and children of elementary school age.

"These children happen to have the COVID antibodies or be positive for COVID," he said. "But those were not the symptoms they showed when they came in to the hospital system."

He told reporters that the Center for Disease Control has asked New York to develop national criteria so that other hospitals in the U.S. will know what to look for if the case warrants.

The New York State Department of Health has issued an advisory about the inflammatory disease, called "Pediatric Multi-System Inflammatory Syndrome Associated with COVID-19," informing hospitals and doctors of the condition, as well as guidance for testing and reporting.
