In Switzerand, the wide-spread use of COVID tracking Apps has been hampered by political, psychological , regulatory and technical (e,g, updating iPhones to iOS 13.0) problems. Only less than 2 out of 8.5 millions of inhabitants have decide to install the Swiss version of th App.
Now, another problem arises: false positive alerts in protected environments, e.g.in hospitals. Are such false positiv alerts a real or an imaginary problem? Is it necessary to suppress the activity of the App whil working as a nurse or a doctor?
In Portugal, in a population of 10.000.000, about 2.500.000 have downloaded the app sponsored by the government, but only 566 people have inserted the code for their positive test in the app... :( I think it's a psychological thing, they are afraid of admitting the positive test, even thought the app doesn't have any personal information about you...

Carla Costa thanks a lot for this important observation which highlights the psychological barriers (fears of being discriminated against!) to active participation.
It is worthless in India. The application security is a big question, intention of Govt is not clear.
The approach itself is false, while infected people should be confined especially that we don't know yet how exactly the Covid-19 spreads... The apps should play a preventive role in the fight against Covid-19, that's what we explained in our article titled: "Putting the world back to work: An expert system using big data and artificial intelligence in combating the spread of COVID-19 and similar contagious diseases"
By reading our article you will see that our expert system is a preventative measure applied on people who are suspected to be infected while the contact tracing applications are used on confirmed infected people's that should be confined. In addition, our expert system is more accurate even with a small percentage of applicants compared to contact tracing applications.
You welcome dear Dr Hans-Ulrich and thank you for paying attention to this important point.
