They should self-isolate for 10 days, commencing from when the symptoms first started (if asymptomatic: from the day the test was taken). If you develop symptoms after your test, restart your 10-day self-isolation period from the day the symptoms start. You should Report a Case if any test results are positive. If your child or anyone in the household has tested positive, the rest of the household should self-isolate for 10 days.
Your child can return to the Academy after 10 days self-isolation, even if they still have a cough or loss of smell/taste.
