I think they need to temporarily empty the hospital, then runa robot through it with the radioactive stuff they use to irradiate food. That would sterilize the place, making it safe for a while.

To save money the NHS have large wards.....

However, in USA, all new hospitals, and many older ones are converted to single patient wards.

This reduces cross infection tremendously.

Also strict hand washing and disinfection.

There is also a solid state anti-bacterial coating that can be applied to glass, (invented in Japan) and now widely used in US hospitals.
