It persists on surfaces. It can be picked up off a surface and

mainly being transmitted due to face to face transmission, or via
infected droplets being left on surfaces. Those infections do not
reliably fall within the range of bluetooth.
The PACT protocol, in its specification, mentions the issue and
suggests a possible solution: a phone (or, actually, any thing that
has Bluetooth and runs software) left on the surface on sensitive
places (such as a shop counter), redistributing the IDs it detected.
This has the feel of tech looking for a solution. If I walk into 2
railway stations two times a day five days a week. take two trains a
day. A supermarket three times a week. open and close a park gate twice
a day. How many indirect bluetooth proximity alerts will I receive?
How long will it be after getting possibly thousands of covid infection
warnings that I decide to turn bluetooth off? It is not as if there is
any reliable anti body testing going on. So the only action to take is
to go into self isolation for another two weeks.
This does this idea improve targeting? It looks more capable of just
pissing people off.
