Happy New Year, all. I think it's only right to add my own data point in case anyone else is wondering.
I tested positive on the 24th of December and finally negative (antigen/lateral flow test) yesterday on the 31st of December.
My first test yesterday had a very very faint line on the positive field and 2nd was entirely clear. I did another today and it was negative.
Let's hope we get some return to normalish travel this year and thanks for those who responded.
