I hope somebody can help as I am struggling to find the answer to this. My son tested positive as of last Monday which meant he had to isolate for 10 days and the rest of the family for 14 days. Two days later, I tested positive which then meant I only had to isolate for 10 days. Do the rest of the family then begin their 14 day quarantine again from my first days symptoms or do they continue their count from the first contact with a positive person?
