Apple and Google are offering the API, however PHAs must develop their very own contact tracing apps. In an try to advertise adoption and keep away from fragmentation, use of the API will probably be restricted to 1 app per nation — although there could also be some exception if a rustic has opted for a state or regional strategy. A handful of US states, together with Alabama, North Dakota and South Carolina, plan to make use of the API for their very own apps.
Whereas 22 international locations have requested the API, that doesn’t imply they’ll all put it to make use of. The UK stated it received’t use the Apple-Google mannequin, and international locations like Australia have already rolled out their very own options. Nonetheless, Apple and Google count on extra international locations to request the API within the coming weeks, and the World Well being Group (WHO) stated it is going to launch a contact tracing app for international locations that don’t make their very own. The WHO might use the Apple-Google tech.
Know-how can assist well being officers quickly inform somebody they might have been uncovered to COVID-19. At this time the Publicity Notification API we created with @Google is obtainable to assist public well being businesses make their COVID-19 apps efficient whereas defending person privateness.

On its finish, Apple is including publicity notification performance to iOS 13.5, launched at this time, so its gadgets ought to work with the API and iOS apps that use it. Google is rolling out a Play Companies replace at this time, so Android gadgets operating 6.zero and above will probably be appropriate.
As beforehand reported, PHAs that use the API should conform to solely use the tech for COVID-19 contact tracing. Customers should consent earlier than the app makes use of the API and earlier than they share a optimistic take a look at consequence. Customers can even flip publicity notifications on and off. Apps can’t request entry to location knowledge, and they don’t seem to be permitted to make use of person knowledge for issues like focused promoting.
The API will enable PHAs to outline what constitutes an publicity occasion and decide transmission threat components. As an example, a PHA might resolve to ship publicity notifications when you have been uncovered for a number of minutes (say, on public transit) however not when you have been uncovered for a couple of seconds (passing somebody on the sidewalk).
Regardless of safeguards put in place to guard person privateness — all metadata related to Bluetooth will probably be encrypted — the API and phone tracing apps will possible elevate privateness considerations. And but, to be really efficient, they’ll want widespread adoption.
