Sewer tests in Massachusetts lend support to this German study. As a Mainer, I will refrain from gratuitous comments on Massachusetts hygiene. But in all seriousness, the more widely spread the better.
The number that should decide policy in the coronavirus crisis is the denominator-- deaths as numerator, but out of what share of the population? The coming widespread antibody testing will give us a better denominator.https://spectator.us/covid-antibody-test-german-town-shows-15-percent-infection-rate/ …

Don't we have more info/examples like this? Remember the cruise ships that were stranded off of FLA. The Pres said they studied the passengers on 2 ships that docked. We have info from the USS Teddy Roosevelt too. And there is another cruise ship full of passengers off Uruguay.

Could we do random testing now like Germany did in the town? Do we have to wait for the fingerstick test to start randomly testing? And how about selectively testing those who think they had this virus in Dec., Jan., or Feb. to see if those people have have antibodies?

Antibody tests are great for research, but dangerous if used to predict individuals' status. Let's say an antibody test offers ~95% sensitivity & specificity. If we extrapolate from Gangelt, using this test would mean that 23% of people would falsely be considered immune.

Test 100,000 random people. 15k will actually be positive, 85k negative. You would expect 18.5k positive results. 14.3k would be positive people (0.95×15), but 4.3k would be negative people with the wrong test result (0.05×85) So 23% of positive results out would be wrong.

Bingo! The title of my weekly research note is ‘It’s all about the denominator’ the study you site is discussed.https://ironsidesmacro.substack.com
