Italian report showing extensive % with CoV antibodies

You need to google translate this article from Italian, but apparently in one part of Northern Italy, out of 60 healthy blood donors, 40 were found to have antibodies against SARS-CoV-2. This is remarkable, contributing to the growing notion that there are more asymptomatic infected that we thought, maybe more than half of those infected asymptomatic (as seen in Iceland where they are testing broadly). This would be Big! Implying in some of these hard hit areas like N Italy and NYC they may be closer to herd immunity than anyone thought! It bears watching and I can’t wait until we have more blood antibody tests and can figure out what to make of that information
