You go hiking in the woods with some of your classmates. A few days after the hike, your friend Alice calls to tell you she is not feeling well and that she is going to skip soccer practice that evening. She says she has a weird rash on her leg and wonders if she was bitten by a spider while your were hiking. She sends you a photo of the rash.

While you are waiting to see a clinician, you review answer Alice's questions about Lyme disease.
