Apple and Google have launched coronavirus exposure notifications without an appon September 2, 2020 at 10:15 am

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, then notifies someone’s close contacts if they test positive for coronavirus. The original system launched in May and has since been adopted by six states in the US and at least 15 countries since. Four US states will be the first to sign up to use the revamped system, Apple and Google said in a conference call. These are: Maryland, Nevada, Virginia, and Washington, DC.

How it works: In states or regions which 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 they are able to access it. Apple users just need to tap the screen to enable it. Android users will still have to download an app–however the app is automatically generated for public health authorities by Google. 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. Anything that makes it easier for agencies to set up contact tracing apps should help to boost adoption in the population at large, which is crucial if they are going to help break the chain of infections. However, it’s still not a panacea. These apps will only ever be part of the overall fight against covid-19, which still heavily relies on manual contact tracing, social distancing, and mass testing.
