Exposure Notifications
Another part of fighting such an infectious disease is carefully tracking exposure, and understanding when you have been exposed so you can isolate or take other precautions for yourself and others. A number of contact tracing apps were used around the world to help with this, but one of the most impressive is the Exposure Notification System, a joint project between Apple and Google to make contact tracing easy for the average user with a simple update on your phone – one that fully preserves your privacy.
