Teruei Hayashi, a fifth-grade elementary school student, was playing dodgeball in a park when he felt something was wrong with his body. He continued to have a high fever and severe diarrhea, and I visited a nearby hospital, but it was difficult to find the cause.

Since it is similar to "Kawasaki disease" that occurs in infants, it is difficult to judge and even if you visit a hospital, it takes a long time to diagnose. At least 64 people had been diagnosed with MIS-C in Japan.
