10 days ago I was pinged by the covid app to isolate as I was supposedly in contact with someone who tested positive for Corona. Like a good person I stayed at home. Did a lateral test every day. I even did a PCR test. All negative. This ended on Monday evening.
This morning I again received a message to isolate for 10 days as I'm again been in contact with someone.
BUT and it's a big but I've not been out apart from being in the garden. How can I have been in contact if I've not been anywhere. Even yesterday I didn't go out.
