How it works: In states or regions that have enabled the “Exposure Notifications Express” tool, a prompt will flash up on phones with the latest version of Apple or Android’s operating system, informing the user that it’s available.
The news: Apple and Google have announced they’re expanding their coronavirus exposure warning system so health agencies can take part without needing to create a customized app.
It’s a significant upgrade to the system, which uses Bluetooth to work out if people have spent extended periods of time near each other and then notifies the close contacts of someone who tests positive for coronavirus.
Maryland, Nevada, Virginia, and Washington, DC, will be the first to sign up to use the revamped system, Apple and Google said in a conference call.
All the agency has to do is provide Apple and Google with some basic information and set up servers to host Bluetooth keys and exposure verification.
Why it matters: It’s a promising development at a time when excitement around contact tracing apps has distinctly cooled.
