The dangerous Kawasaki Disease-like syndrome occurs in a small number of children exposed to the COVID-19 (SARS-CoV-2) virus. MIS-C is an autoimmune reaction where the COVID appears asymptomatic, but the immune system overeacts to the virus and begins attacking health tissues in the body. It causes severe causes inflammation of the heart, lungs and other vital organs.
