A 19-year-old man presents to urgent care with a 5-day history of a dry cough. He says he has “felt warm” but didn’t think to check his temperature. He also complains that he has been weak, with a decreased appetite. He notes that his girlfriend had an upper respiratory infection a couple of weeks ago, but other than that he’s had no exposure to anyone who’s been sick. He has not traveled anywhere recently, and he has no recent history of weight loss or medication use.
