For UK residents (or those who can spoof their IP location) BBC radio 4's 'Inside Science' programme covered the engineering of buildings, public transport etc. to control infection:
https://www.bbc.co.uk/sounds/play/m000jxvpPerhaps most interestingly, starting at 9:05, Birmingham University (UK) have developed anti-bacterial surface treatments with very long lifetimes - several years at least. Bacteria are killed within milliseconds of contact; they are very sure they will be equally effective against coronavirus but need to test it when their labs, closed by the lockdown, become available again (a few weeks work).
The process involves nitriding to bind anti-bacterial chemicals such as bleach or chlorhexidine to the surface. It has been succesfully trialled in the Royal Navy for 12 months. It can't be retro-fitted to existing surfaces but they are investigating films that can be applied. This sounds very promising and a relatively cheap way of eliminating risks of contact transmission in public places, especially hospitals, by replacing light switches, door handles, water taps etc.
No doubt the bureaucrats will manage to kill it in short order.
[EDIT] Corrected the programme name from 'Science Direct'. No idea where that came from.
