The Case:
An otherwise healthy 3-year-old presented to the emergency department with a chief complaint of a pruritic rash for 2 days that started on the back and progressed down the arm to the hand. The child and his family were migrants recently arriving in the United States from South America and currently staying at a migrant shelter. The patient’s blood pressure was 104/60 mmHg, heart rate 100 BPM, respiratory rate 22 BPM, oxygen saturation 97% on room air, and temperature 37ºC (98.6ºF). On examination, the child was overall well-appearing, and significant only for a crusted-over patch of lesions was noted at the C6-7 dermatome on the child’s back lateral to midline, clustered papulovesicular lesions along the outer side of the left arm and involving the left hand along the C6-7 dermatome. What is causing the patient’s rash?
