Kawasaki disease mainly occur in young children below 5 years.Coronary artery aneurysm (CAA) is one of the most dreaded complication of   KD. The illness is very rarely seen in infants younger than 2 months.  Case Report:  An unusual presentation of KD in an infant as early as 60 days, was investigated, received immunoglobulins and aspirin, but due to delay in diagnosis developed CAA and had prolongrd derangement of lab parameters. Conclusion: We need to consider KD even in an infant with a case of prolonged fever so that CAA complication can be prevented.
