This doesn't appear dissimilar to other episodes. There have been a number of people testing positive to antibody tests that had no idea they ever had it, and shared households with families and beds with partners throughout, but are the only one in that house to test positive. Yet some "super-spreader" events appear to give an impression it is easy to transmit.
How accurate are the antibody tests? I know some if not most can produce false positives by picking up earlier corona virus infections that weren't/aren't Sars- CoV- 2.
I ask because I'm not up to date on current antibody tests in use in this country.
It depends on the test but specificity is pretty good these days, close to 100%. Sensitivity can be more of an issue but over 95%.
