Track and trace just called as my son had positive lft then pcr on 3rd. I tested positive on 27.12,I've not had texts and emails from track and trace saying I've been identified as a contact of a positive case and so I need to isolate for 10 days,that isn't right is it? If he likely caught it from me anyway,my isolation is due to end on 6th,his day 10 is 13th
