   Le sigh. On that day I had recording in the studio with 2 external guests who both say they were negative. My tests (last Thursday, Saturday, will do another one today) are negative. You just can’t trust people anymore :(

     @jwildeboer I wouldn't jump straight to malice or incompetence. They could have tested negative before but positive after?
     
     I don't know how far the app traces. Could they have passed through some space that day where someone who was present would later test positive? Would that trigger a warning to you?

     @clacke The algorithm is quite straightforward. It collects derivative keys with signal strength for the last 14 days. If someone gets tested positive, the daily keys that allow the derivation are shared. Should this result in a match, it check for risk factor based on time of infection and signal strength to determine risk that possibly leads to a warning.

     @jwildeboer Do that and keep in mind that the CWA does not know when your contact was infectious and has a buffer. Your contacts may really have been negative that day.

     @jwildeboer I understand that, but as I said, CWA sent alerts to my contacts for days were I was not infectious. As the kids already were positive we were as accurate as possible with our tests and the test centers. Maybe CWA does not care wether you are boostered or unvaccinated? However: stay healthy and be careful!

     @mobaer Of course the CWA doesn’t care about my vaccination status. Because that has nothing to do with my exposure risk. It’s task is to tell me if I had exposure so I can act accordingly. Which I’m doing right now.

     @mobaer They are positive now and shared that with the CWA. So they know on which days in the past they were infectious. I got the warning and do what is needed. But I specifically asked today and both denied they were positive. I’ll accept that. But I don’t trust them. That’s all.

     @jwildeboer there is nobody to blame. CWA takes a date prior to the positive test and starts warning the contacts. My wife got a warning for a contact with me five days back, while I had two trustworthy tests a day that were negative everyday until the PCR was positive. It’s absolutely possible that they were not positive when you met.
