Severe Bacterial Infection Initially Misdiagnosed as MIS-C: Caution Needed

Abstract

Working in the era of the novel coronavirus disease 2019 can predispose to cognitive bias. We present a case of life-threatening bacterial infection misdiagnosed as multisystem inflammatory syndrome in children. While multisystem inflammatory syndrome in children-related myocardial dysfunction is now a well-recognized complication of coronavirus disease 2019, a rigorous differential diagnosis approach, notably for infectious etiologies, is paramount.
