These symptoms are concerning for Kawasaki disease - an inflammatory condition that can affect the blood vessels, including the coronary arteries. One of the potential complications of this disease is coronary artery aneurysms. An echocardiogram is the most appropriate investigation to assess for this complication.

QuestionComment
Hi there! Kawasaki disease has a typical fever lasting >5 days, unlike scarlet fever, and is diagnosed based on the specific clinical criteria described above. With scarlet fever, although there is overlap, it would be very rare to have the features above, without evidence of pharyngitis, and diagnosis would then be confirmed with e.g. throat swab. The rash (at least in exams) is often described as 'sandpaper-like' too. Hope that helps!
