So apparently ( hse guidelines) only class those you have been in contact with 48 hours pre symptoms starting close contacts for tracing... I tit you not yet we isolate for 14 days if we are deemed a close contact now and only tested if there are symptoms ( hence hse not wanting you to contact anyone pre test result ) there is absolutely no way she can be sure it was christmas day, I wouldn't wish it on anyone but duck off with the stigma crap , put down the phone and leave us be we are well aware about Covid plus we weren't all over the place mixing
