One night, when her face turned puffy and painful from what she thought was a sinus infection, Jessica DeVisser briefly considered going to an urgent care clinic, but then decided to try something "kind of sci-fi." She sat with her laptop on her living room couch, went online and requested a virtual consultation. She typed in her symptoms and credit card number, and within half an hour, a doctor appeared on her screen via Skype. He looked her over, asked some questions and agreed she had sinusitis. In minutes, Ms. DeVisser, a stay-at-home mother, had an antibiotics prescription called in to her pharmacy.
