Contact tracing is used all over the world. It’s based on the knowledge that someone with a contagious disease will infect a certain number of people. With the coronavirus, it’s likely two or three. So the goal is to track down anyone in recent contact with a newly diagnosed patient, then monitor the health of these contacts while they stay at home for the period of time when they might become infected — roughly two weeks — or are held in an isolation facility.
Now think about having a application on your smartphone that tracks your movements (anonymously) and alert you if you’re in close contact with someone who has had Covid-19.
