Prior to the COVID-19 pandemic, a few papers had suggested other coronaviruses could cause Kawasaki disease. Burn has applied for a National Institutes of Health grant that would allow her to perform whole genome sequencing on children with different types of MIS-C, as well as children who were diagnosed with Kawasaki disease before the COVID-19 pandemic, to find differences and similarities. Scores of UK and US children have been affected by a rare inflammatory disease linked to coronavirus. Given the high likelihood that MIS-C results in much more severe symptoms than the typical case of Kawasaki, “the overall spectrum is more different to Kawaski than similar to Kawasaki,” he concludes.
