Why the study?
MIS-C can present with a severe clinical course requiring prompt treatment, but distinguishing it from similar illnesses can be confusing.
Influenza A can present with severe systemic symptoms that mimic multisystem inflammatory syndrome in children (MIS-C), highlighting the importance of comprehensive viral testing in differential diagnosis.
Answers are grounded in this paper and cite their sources.
MIS-C diagnosis in febrile children warrants viral testing to exclude mimics like influenza; this case leaves open optimal diagnostic algorithms.
Multisystem inflammatory syndrome in children (MIS-C) might present a severe clinical course that clinicians should promptly treat. However, distinguishing other illnesses similar to MIS-C could be confusing. Here, we presented a two-year-old boy diagnosed with MIS-C owing to three days of fever, gastrointestinal findings, mucosal involvement, and elevated inflammatory markers, whose respiratory virus panel resulted in influenza A.
