A 5-year-old girl presented with a 2-day history of a widespread pruritic rash that began while the family was on vacation. The rash appeared suddenly as small pink macules and progressed to papules and pustules. Her brother had a similar-appearing but milder rash. She denied fever, chills, or constitutional symptoms. On further questioning, her father reported that she and her brother had been in a hot tub at their vacation home.
