This year, a German businesswoman arrived in Washington DC and promptly developed a painful sinus infection. She searched online and found a local doctor, Suzanne Doud Galli. But instead of ordering a taxi to visit Dr Galli’s office, the patient arranged a virtual consultation via her smartphone from the comfort of her hotel room, with the help of an app called HealthTap.
The app’s algorithm matched the patient’s symptoms with Dr Galli’s expertise. Dr Galli prescribed medicine and sent the prescription electronically to a pharmacy near the patient’s hotel — all in about 10 minutes.
