Re: "Smartphone apps are the best way to provide that tracing need"
Indeed and the numbers from Germany would seem to back this up: 18 million downloads, 5,000 notifications in 3 months in a country with a case load of around 10000 per week. A great success according to the Health Minister, but what else would he say?
BTW. you could, of course, use the same app to map the spread of other dangerous illnesses*. But, having been developed by SAP, this would obviously be an add-on for another € 20 million.
* Apparently, there are indeed other dangerous airborne respiratory diseases! As if SARS-COV2 isn't enough there is something called influenza (or "latin flu") which can also kill people! Run for the hills!
