So someone at DHs work tested positive last Wednesday, those in close contact were told bu HO to self isolate. On Monday a member of staff said they had taken a test (no symptoms) and it was negative. They have been told its therefore ok to return to work! I'm right in thinking that this is not ok? That there is incubation period and that 14 days standard regardless? The person in question came into contact with a positive case.... worried as have 90 year old DGM in hospital.
