On the BBC news there was an interview with a nurse who was off work self isolating with a viral illness. She had not been offered an opportunity for a corona virus test so she was uncertain whether she was staying off work for longer than necessary and she was not offered the peace of mind that might be gained from knowing whether the episode had left her with some degree of immunity against corona virus.
By contrast I remembered the way various politicians, professional footballers and celebrities had quickly been able to report that they had corona virus.
Right now there will be retired health professionals in self isolation with flu like viral illness. They have no way of finding out whether this episode has been corona virus and whether it has left them with some degree of immunity, if asked to volunteer when things get busy.
The best use of testing kits for the U.K. seems badly thought through to me.
