Re: How will they know it's a false alarm?
Only the test can tell you if you have it. One of the issues is asymptomatic carriers.
Just like all the Track & Trace, leaving details at bars, quarantine, isolation and testing on symptoms everything is based on trust. The App is just an additional tool however the single biggest improvement will come from the population behaving responsibly.
It works both ways and currently we are lucky to live in a country where we are not forced to be monitored like Singapore. Unfortunately there appear to be so many who do not give a stuff that at some point we are going to end up with another major outbreak. All that we (and everyone else) are doing are suppressing Covid19. Nobody is beating it or eradicating it, that is the nature of the virus. Looking at the research on immunity they only ways out of this are:
A viable vaccine with sufficient take-up to be effective.
Live with the virus and no restrictions accepting a significantly higher risk to the population as a whole.
Continue with the restrictions (up and down) and to try and to make the best of it whilst having an increasingly horrendous economic situation.
Biting the hand that feeds IT
