Re: Sixty seconds on . . . the contact tracing app

Dear Editor

Not clear if triggering the app to report symptoms automatically leads to a test?

One assumes it would or we could have a large number of people repeatedly self isolating for 2 weeks without knowing if anybody is ill with covid. Please can this be clarified.

We are not yet being told what percentage of tests are positive, what is thought to the the false negative rate and how many are asymptomatically spreading from pyramid 4 data.
