California finally has an app that links the Apple/Google contact tracing API with the state public health system
This is the one that exchanges rotating random numbers between phones over bluetooth, building a pseudonymous list of other people’s phones you’ve been near. You can use the app to report a positive covid result linked to your numbers, or check for exposures against its local list of contact events.

I remember listening to a podcast on the design way back in…May? It’s an interesting approach to balancing a legit use of tracking vs. limiting chances for abuse of the data by limiting how much is actually collected.
It’s woefully incomplete, of course, but then it’s not like interviews would be complete either, even if we had enough trained people to run them for every single patient.
