Which of the following statements is true regarding the signs of Kawasaki disease?

Kawasaki disease is a condition that primarily affects children, usually under the age of five, and is known for its classic signs and symptoms. The true aspect of the disease is that rash and edema are indeed common symptoms. In Kawasaki disease, the rash often appears as a maculopapular rash, and peripheral edema can occur, particularly in the swollen hands and feet. These symptoms reflect the systemic inflammatory response that is characteristic of the disease, which can also include fever, conjunctivitis, lymphadenopathy, and oral mucosal changes.

Understanding that most cases occur in younger children rather than adults highlights the demographic focus of the illness and clarifies why the other choice is not accurate. Additionally, conjunctivitis associated with Kawasaki disease is typically bilateral, which makes the statement about it being always unilateral incorrect. It's also important to note that multiple symptoms of Kawasaki disease can be present simultaneously, contrasting with the idea that only one symptom can occur at a time.

Thus, the acknowledgment that rash and edema are common in Kawasaki disease underlines the nature of the disease and its multifaceted presentation, confirming that this is the accurate statement regarding the signs of Kawasaki disease.
