Its pretty difficult to surge test before you identify an outbreak though?
You regularly mention a better test and trace system but I still don't really understand what system you want to see implemented.
That is the thing though - you don’t surge test before you have an outbreak; what you have is a system which can pick up the first few people in a potential chain of infection and then stop the disease before it ever becomes an outbreak.
In an ideal world you’d have people phone up when they get symptoms, someone would be despatched to where the person is and test them (and the rest of the people in the house), whilst that is happening the phone operator is getting a list of contacts. If they test positive for something posing a risk, they isolate and people are sent to contact the contacts, obtain their contacts and test them, and so on down the line until you’ve stopped it spreading.
What surge testing does is wait until local cases are of such a scale they can’t really be contained, and then starts. As a warning or prevention system it’s rather useless, sort of like a smoke alarm that only starts working at 1500 degrees centigrade.
