It's been reported today (April 4) that
New York state has recorded 630 more coronavirus deaths, another daily record that takes its [death] toll to 3,565.
Most deaths have been in New York City. The state now has almost as many cases - over 113,000 - as the whole of Italy.
But clearly Italy has had more Covid-19 deaths, over 15,000 (15,362 on the same April 4 day), which puts the case fatality ratio (CFR) estimate substantially higher in Italy than in NY.
The CFR is sensitive to the number of asymptomatic cases, i.e. cases that should be included in the CFR denominator, but might not be so because not enough testing is done on the asymptomatic individuals. (There are also other factors that can drive up the CFR "for real", like the age structure of the population, and smoking history.)
But to stick to a public-health measures comparison question (as opposed to [all] other confounding factors), how do NY and Italy compare in terms of testing, per capita?
