Taiwan operates comprehensive quarantine surveillance

When the phone belonging to an American University student in Taiwan, who was subject to 14 days' quarantine after returning from Europe, ran out of battery power, in less than hour he had received phone calls from four different local administrative units, a text message notifying him he would be arrested if he had broken quarantine, and a visit from two police officers. The phone tracking system uses phone signals to triangulate locations of the more than 6,000 people subject to home quarantine; an alert is sent to the authorities if the phone is turned off for more than 15 minutes.
