Q. A 25-year-old Yale University student presents to his primary care physician. An avid outdoorsman, he has always been in good physical health and spends most weekends hiking or climbing mountains. A few months ago, after returning from a camping weekend with his friends, he noticed a rash on his calf along with flu-like symptoms. The rash and symptoms resolved on their own and he attributed them to overdoing it on the trip. Recently, he started having symptoms of dizziness, syncope, dyspnea, chest pain, and palpitations that lasted for several weeks. His physician obtains an EKG: shown in the image. Knowing the student’s disease, what other disease is carried by the same vector?
