As I never leave home except for medical appointments I doubt that it will ever be necessary to contact me anyway.
as a scenario in 4 months time you go to your Drs appointment. Another in the waiting room is CO-VID 19 positive but asymptomatic....they are only there for an ingrowing toenail....after some banter their Dr decides to test them for CO-VID19 .. just for a laugh Once a positive test is confirmed anybody that was in the waiting room that has the app and spent 15 minutes in the waiting room the same time as the asympyomatic patient is automatically notified. Their exposure can be digitally traced down to the second and the mm.
On the way home one of those with the app go to the chemist and the reject shop because the dingleberrys were on special.
Anybody that has the app and spent 15 minutes and came within catching distance at the chemist and the reject shop will be
notified about the same time as the original phone owner that was in the DR surgery is notified
As you do not have the app it takes a bit longer (days possibly) to check the appointment times manually to see if you fall into the time period when the asymptomatic patient was in the waiting room. As the manual times/distance trace can only be estimated and larger overlapping scatter gun like sample of people will be notified manually.
Days later you test positive...on the way home from the Drs when you were first infected you went to the chemist and the reject shop too because the dingleberrys were on special.
Because your movement times and contact distances can only come only come from your memory manual tracing at the chemists and reject shop eftpos or healthcare card tracing may mean that 100's of people will need to be notified and tested....but it's too late by then...dys lter the horse has bolted and a cluster infection is born..........
The app gives expediency to the contact trail....
To use an a simple analogy think that the app is notifying you that you have had an infectious contact via email almost instantly whereas with no app it's akin to being notified via snail mail days later after a health boffin public servant does some gazintering and postulating.
