You are completing your Pediatrics rotation and are working in the pediatric emergency department for the night. At 4:00 PM, your preceptor asks you to see Austin, a 3 year old male who has presented with a fever and sore throat. As you enter the room you notice that Austin is awake and alert, and being held by his father.

Austin’s father also noticed that he felt warm at that time, and measured a temperature of 38.1°C. Which of the following options should be obtained on history?
