A 2-year-old child is admitted to your hospital team. The child's primary care doctor has been following the child for several days and has noted her to have had high fever, peeling skin, abdominal pain, and a bright red throat. You are concerned because two common pediatric problems that could explain this child's condition have overlapping presenting signs and symptoms. Which of the following statements comparing these two diseases in your differential is true?
- Neither has cardiac complications
- Serologic tests are helpful in diagnosing both
- Only one of the diseases has mucocutaneous and lymph node involvement
- Pharyngeal culture aids in the diagnosis of one of the conditions
- A specific antibiotic therapy is recommended for one of the conditions, but only supportive care is recommended for the other
