So as well as the public she met in her constituency surgery, and Boris, and her mum, she will have had contact with many of her departmental staff. Who will have contact with staff in other departments. And Boris will have had contact with the No 10 staff, who similarly will have contact with other civil servants. So it could spread quite quickly in Whitehall, leaving the emergency response groups in each department having to deal with their own business continuity issues as well as trying to reassure the general public. It clearly shines a light on how easily it can affect the population, and the ripples that will increase the risk of exposure. I hope the Queen and Philip don't catch it after their Boris contact.
One of DS's colleagues was sent home from work in an ambulance today after exhibiting all the symptoms and having been in contact with someone who just returned from Italy (travel industry).
