A Professor Sharn Griffiths on Radio 5 Live a few minutes ago. She was involved in the control of the SARs outbreak in Hong Kong and talking about testing prior to entry to a nightclub, football ground etc. and the time it takes for lft and the fact that tests are progressing all the time. She suggested maybe: "...test at home & get something on your phone, an app or something....". Maybe BT is still alive and well and not too far away.
