Cardiovascular complications are unfortunately most common in young infants and it is in this age group, incomplete Kawasaki disease (IKD) is more frequently reported. Because IKD is a diagnostic dilemma, any sign that could help early diagnosis, such as BCG reactivation is useful. Here we report on an infant less than 3 months old with IKD wherein, BCG reactivation helped us in making the diagnosis. In this article, we highlight the usefulness of this sign for early diagnosis of IKD, especially in countries where BCG vaccination is still part of the immunization schedule.
