What is Exposure Notifications System?
In May, Apple and Google jointly launched the Exposure Notifications System (ENS) which consists of the Exposure Notification API to supplement manual COVID-19 contact tracing efforts. Apps developed by public health authorities based on the Exposure Notification API use privacy-preserving technology and Bluetooth Low Energy. A user can choose to turn on or off, the Exposure Notifications.
Traditional methods of contact tracing are critical to containing the spread of infection. Technology can support and augment these efforts by allowing public health authorities to quickly notify people who may have been exposed to a person who has contracted COVID-19, including those the person might not know directly. This starts with Exposure Notifications on your smartphone. These will help your public health authority alert you if you’ve been exposed to COVID-19.
