Nearly six hundred children were admitted to the hospital with a rare inflammatory syndrome associated with the novel coronavirus during the four months of the coronavirus pandemic in the United States, Centers for Disease Control and Prevention (CDC) said on Friday.
Multisystem inflammatory syndrome (MIS-C) is a rare but severe condition that shares symptoms with toxic shock and Kawasaki disease, including fever, rashes, swollen glands and, in severe cases, heart inflammation.
It has been reported in children and adolescent patients about two to four weeks after the onset of COVID-19.
With rising COVID-19 cases, there could be an increased occurrence of MIS-C, but this might not be apparent immediately because of the delay in development of symptoms, said the report.
As of July 29, state health departments reported a total of 570 MIS-C patients diagnosed with the illness from March 2 to July 18.
Among the MIS-C cases, all patients tested positive for COVID-19 and 10 died, the CDC said in the report.
