June 29, 2020 -- Nearly 300 children in 26 states fell ill with a mysterious COVID-related inflammatory condition between March and May, a pair of new studies show. Six of the children died.

The studies are the most detailed accounts to date of the illness called multisystem inflammatory syndrome in children, or MIS-C. And they’re giving pediatricians and parents a better idea what the condition looks like when it strikes.

The reports paint a picture of kids and teens who become severely ill, with at least four organ systems involved in the illness. Eighty percent of kids and young adults in the study, who were all under the age of 21, were treated in the intensive care unit, and 20% needed ventilators to help them breathe.

MIS-C is different than the severe course of COVID-19 that can imperil medically fragile children. MIS-C is a condition that seems to hit previously healthy kids days to weeks after they’ve fought off the virus that causes COVID-19.
