    Snippet: When we consider the bottom half of figure 6 and look at the impact on the proportion of the population able to leave quarantine, unlike previously, the number of false positives dominates when there is a lower specificity. So there are many more people leaving the quarantine, even when the prevalence is very low (0.1%). This may be desirable to some who favour increasing economic and social activity, but it is of course at the cost of further in.....
    Document: When we consider the bottom half of figure 6 and look at the impact on the proportion of the population able to leave quarantine, unlike previously, the number of false positives dominates when there is a lower specificity. So there are many more people leaving the quarantine, even when the prevalence is very low (0.1%). This may be desirable to some who favour increasing economic and social activity, but it is of course at the cost of further infections. Decision makers and the public need to be aware of the trade-off being made. The dangers of neglecting uncertainties in medical diagnostic testing are pertinent to this decision [26] , particularly if immunity passports become prominent in the strategy to end the current social distancing measures.
