This is an acute condition that mostly affects children.
The study found that incidents of this new Kawasaki-like disease increased during the COVID-19 outbreak, as compared to cases in the last 5 years. None of the children sampled in the study died but they did have more severe symptoms, like heart complications, than those who only had Kawasaki disease earlier.
However, the number of cases was still small and COVID-19 is generally less harmful to children. Experts suggest that while COVID-19 affects the lungs directly, this inflammatory disease seems to be caused by a delayed response from the children's immune systems.
But again, it is too early to tell for sure, although it is best to talk to your doctor if you notice your child in any discomfort.
