A girl born at 41 weeks' gestation was apneic upon delivery and had a rash from head to toe. She was intubated and sent to the NICU. Skin exam showed erythematous papules with purpura, crusting, and ulceration that involved the face, trunk, arms, legs, palms, and soles. The mother had a history of spontaneous abortion, but was up to date on vaccinations and her screening exams were normal. What's your diagnosis?
