The Centers for Disease Control and Prevention issued a health alert to physicians Thursday on what has emerged as a rare but potentially deadly condition linked to COVID-19 in children.
The illness, which the CDC calls "multisystem inflammatory syndrome in children," or MIS-C, has been reported in at least 19 states and Washington, D.C. It was previously referred to as pediatric multisystem inflammatory syndrome, NBC News reports.
