Oh ok! Brilliant idea! Let's control the infection! Fab!
Now if you can tell me how we do that when:
You can't tell if people have the bastard thing reliably without a pcr test which takes hours to run
Hospitals have very limited space for people to wait in isolation before going up to a ward
Hospitals have very limited isolation spaces on the wards
The infection can spread with short periods of contact and in the air
Staff can be positive without feeling ill
Any hospital has huge numbers coming in and out especially they try to keep appointments running
Any IPC experts please do volunteer to hit the wards with the teams. They've only been living a nightmare for the last year, they're basically clueless and no doubt you will soon show them how to defeat a highly infectious virus that we have only a limited understanding of even now,
