They say about 5% (edit, that may be critical care rather than hospitalisation; if so, then this is an overestimate) of people who contract the virus need hospitalisation, so if you assume that is the case then there would be about 50k odd cases in NI based on the numbers of confirmed positive tests (I’m ignoring health care workers being tested for the purposes of this exercise).Nonsense that in my view. The figures in New York alone make that estimate nearly impossible, as it'd mean something like 80% of the population have it if you reconcile it with the death toll.
That works out at about 2%-3% of the population which would correspond to the Chinese study.
Impossible to know for sure without widespread, accurate testing.
