May as well forget scanning in

[king1]

With numbers of cases now over 400 a day contact tracing breaks down and is virtually impossible.  The government has previously said that cases more than 200 a day strained their ability to trace people's movements.

record keeping is mandatory in most places, so scanning in is still absolutely necessary.

How do you know that 400 a day makes it "virtually impossible" to contact trace? You have some inside info on that you would like to share?  That 200 number was thrown around very early in the outbreak, i'm quite sure they must have scaled up a bit by now...
