OLYMPIA, Wash. — Health authorities in Washington on Friday said there are now 11 cases of pediatric inflammatory illness associated with the new coronavirus that have been reported in the state.

Department of Health spokesperson Kristen Maki said the cases occurred between April and July. She said according to the latest information available to state officials most of the children were admitted to intensive care units but have since been discharged home.

The Department of Health said Multisystem Inflammatory Syndrome in Children is defined as a patient under the age of 21 with a fever, laboratory evidence of inflammation and severe illness involving more than two organs that requires hospitalization.

Patients must also have a positive COVID-19 test or exposure to a confirmed case in the four weeks before symptoms began, the department said.

Six of the cases in Washington are children 9 or younger and five are in children 10 or older.
