Wife got a COVID-19 exposure notification. The only scenarios where she could have gotten exposed for continuous 15 minutes at max 2 meters (which is the threshold for the notification) would be on Monday at work or yesterday when sewing next to the wall against our neighbor. At work she didn’t see people for that long and they kept their social distances. But it is possible that there would have been someone working one floor above her who got it. But then again, I have received matches with a device of that informs of an infection last night when my phone was close to that wall against our neighbor, so it is very likely that she has it.
