Texas Children’s and Children’s Memorial Hermann hospital officials said Thursday several patients have or are suspected to have what’s known as multisystem inflammatory syndrome in children, or MIS-C.

Penny said the Texas Children’s patients, fewer than 10, are on the road to recovery.

Texas’ department of health said Thursday no cases reported to the agency have met their definition of MIS-C, even though Cook Children’s Hospital in Fort Worth publicly announced four cases Tuesday.

Penny said Texas Children’s has reported cases it has confirmed to the CDC.

Texas Children’s diagnosed MIS-C after its testing found those patients had antibodies to the virus — that is, that they’d previously mounted an immune response.
