We report a case of a 3 year-old boy with possible typhoid fever with recent travel to a typhoid endemic area who was primarily managed as a case of multisystem inflammatory syndrome in children (MIS-C). The patient was initially treated for tonsillitis after a 3 day history of persistent fever, sore throat, and constipation. The patient presented later when he deteriorated. Severe acute respiratory syndrome coronavirus (SARS-CoV-2) viral RNA was not detected but the antibodies were positive. The patient went on to develop mucosal, cardiac, and gastrointestinal manifestations and was subsequently treated with immunoglobulins and corticosteroids for MIS-C. Despite the rarity of MIS-C as a complication of COVID-19 infection, the endemic typhoid fever which is relatively more common was not ruled out. The patient additionally received antibiotics for a total of 5 weeks given his unremitting fever. Even during the COVID-19 pandemic, healthcare professionals should carry out timely testing to exclude more probable differential diagnoses, with area-specific common diseases given due diligence.

We describe a case of post-coronavirus disease 2019 (COVID-19) multisystem inflammatory syndrome in children (MIS-C). The 12-year-old child presented with appendicitis-like symptoms in the form of gradually worsening abdominal pain localizing over the right iliac fossa, fever, and vomiting. After an appendectomy, the abdominal pain did not resolve. He later developed orthopnea, bilateral lower limb pitting edema, and bilateral fine basal crepitations. This pointed to MIS-C. We should be mindful of multisystem inflammatory syndrome in children in children with a recent history of COVID-19.
