DD took a PCR test on new year's day. We got the positive result by email/text on Sunday (2nd Jan). So far, track and trace still haven't called. Does it matter? We're trying to figure out when they count day 1 from (first day of symptoms, or day after? Only symptom was 2 days of a mild sore throat) to work out when she can go back to school. Today's LFT was negative.
