A child presents with high fever, conjunctivitis, rash, and strawberry tongue; which condition is most likely?

• A. Scarlet fever
• B. Measles
• C. Kawasaki disease
• D. Roseola

Answer: (C)

High fever with bilateral conjunctivitis, a polymorphous rash, and mucosal changes such as strawberry tongue point most strongly to Kawasaki disease. This pattern is classic for a pediatric vasculitis that affects the medium-sized arteries, and recognizing it early is crucial because untreated Kawasaki can lead to coronary artery aneurysms. While scarlet fever can also feature fever, a strawberry tongue, and a rash, conjunctivitis is not typical and the overall presentation differs. Measles includes cough, coryza, and Koplik spots with a rash that spreads in a different pattern, and roseola presents with a high fever that resolves before a rash appears, not with strawberry tongue and conjunctival involvement.
