NPHET repeatedly cited test-driven case numbers.

Can ⁦ @ronan_glynn⁩ or NPHET please tell us

1. How many positive cases are active or infectious, given that PCRs detect the virus when it is no longer infectious? https://www.irishtimes.com/news/health/coronavirus-61-more-cases-as-glynn-appeals-for-public-solidarity-1.4336951

2. how accurately test-based numbers reflect disease trends in the wider population, given that the number of detected cases depends on the volume & selection of candidates for testing?

3. Why NPHET is relying so heavily on case numbers when they are not a true measure of disease prevalence?

4. Why trends in hospital admissions & deaths, the only reliable indicator of the spread of disease, are not more central to NPHET’s analysis & public engagement on Covid-19?
