MIS-C term became more popular during covid era as the infection started to affect pediatric age group. Now, a large number pediatricians have seencases of MIS-C. Reactivation of BCG scar is less commonly seen in Kawasaki disease and rare to never in a case of MIS-C. Case Presentation: We report a 6-month-old male child who presented with cold and fever. Covid Rapid Antigen Test (RAT) and Covid RTPCR were negative. He continued to have high grade feverwhich is unusual for a case of bronchiolitis and started on antibiotics. Clinical suspicion of MIS-C made and started to work up for the same. Examination revealed reactivation at BCG site with pealing of skin. Further investigations showed elevated CRP and d-dimer with positive anti-SARS COV2 antibody. Diagnosis of MIS-C confirmed and treated with methylprednisolone and IVIG.
