Just wondered if this is common. We all tested positive on the 19th. Dh and I were clear after 7 days but ds (1) is still faintly positive and dd (5) is still very positive (ie test line appears before the control). Neither are symptomatic so I can't see any guidance that implies they need to continue to isolate... but am concerned they still shouldn't visit grandparents etc... anyone else or anyone seen any guidance on this specifically? Thanks!
