2. Case • Anyone want to read this?  • A 30 year-old white female lab technician who lives in Boston, MA presents with an upper respiratory infection, fever, chills, and a rash on her thigh. A week ago, with a group, she took a trip to a camping grounds just outside Boston. She slept outdoors along with the rest of her group. She doesn’t remember being bitten by anything. She is concerned that her rash started small and during the last few days has been spreading. She has no allergies. She had tried an over-the-counter medication, Benadryl, with no rash improvement. Further questioning revealed that she slept on leaves she placed on the grass.
