What is a common finding in infants with Kawasaki disease?

A common finding in infants with Kawasaki disease is the presence of a strawberry tongue, which is characterized by a red, swollen tongue with prominent papillae. This sign is part of a constellation of symptoms associated with Kawasaki disease, a vasculitis that primarily affects children. Other symptoms may include fever, conjunctival injection, cervical lymphadenopathy, and rash.

The appearance of the strawberry tongue is significant because it highlights the inflammatory nature of Kawasaki disease and aids in distinguishing it from other conditions. Recognizing this symptom can be crucial for early diagnosis and intervention to prevent complications such as coronary artery aneurysms, which can occur if the disease is not treated promptly.

The other symptoms provided in the options, while they may be related to different conditions or infections, do not specifically characterize Kawasaki disease. For example, white spots on the tongue could be indicative of a yeast infection or a viral infection. Flaky skin over the body may be associated with a variety of dermatological conditions rather than Kawasaki disease specifically. Blue-tinged skin (cyanosis) might suggest a problem with oxygenation or circulation rather than the inflammatory condition seen in Kawasaki disease.
