MONTREAL -- Specialists at Montreal’s two pediatric hospitals say a greater number of children are being admitted for treatment during Quebec’s second wave, with a rare but life-threatening condition that can develop several weeks after a child gets COVID-19. Multisystem inflammatory syndrome in children (MIS-C) is a delayed immune reaction to COVID that can occur 2-6 weeks after the initial infection. The worrisome trend is the consequence of intense virus transmission this past fall and winter, which has infected many more children than the first wave did, said Dr. Rosie Scuccimarri, a rheumatologist at the Montreal Children’s Hospital, who makes the diagnoses.
