She's not going to be 'at risk of infection' like the regular plebians tho is she?
The NHS have a problem with spread of infection because they have vast numbers of patients and a tiny nursing staff seeing to all of them. Also shared wards, shared bathrooms, grubby air exchange systems, poor cleaning standards etc.
Imagine the staff to patient ratio that Kate's going to get? And the cleanliness and privacy and high standards.
