...how soon will it show if I've been in contact with someone?
I've not downloaded it yet as being vulnerable myself and caring for very vulnerable elderly parents I have pretty much locked myself away for most of the last year.
However, my elderly next door neighbour has just been taken off in an ambulance (in a wheelchair/conscious).
His son was there earlier to check on him and call 111 (we're terraced and my sofa is right next to the window at the front of the house, I couldn't avoid hearing some of the convo), but didn't go inside or stay with him so I'm concerned that it might be Covid related.
We don't have any contact personally but with my parents to consider (dad is on end of life care), I can't be too careful.
Is T & T likely to show if I need to isolate if he has got it?
