Three-year-old Eran might look like a picture of health, but two months ago it was a very different story. One month after recovering from a mild case of Covid, his mother Sara Bittan found herself rushing him to an Israeli emergency room. "He had a terrible rash, all over his body, swollen eyes, red eyes. He was very weak. He didn't have an appetite. He didn't eat for a few days. He was crying a lot. He had pains in his legs, stomach pains. He couldn't go to the toilet. I mean he didn't go to the toilet for a few days. He suffered a lot and all the tests they did for him. It was terrible." Eran was eventually diagnosed with pediatric inflammatory multisystem syndrome, also known as PIMS, and was hospitalized for a week. It also goes by the acronym MIS-C. Eran has since fully recovered. While cases of severe illness and death from Covid-19 remain far more rare in kids than adults, tens of thousands of children worldwide may still struggle with its effects
