Maybe they are being used only for prevalence studies.
The strange thing, though, is that positive antibody tests are being classified as "probable cases" and as these are discovered, they're being reported as equivalent to new
cases in the day to day numbers. In other words, each day there are "newly reported confirmed cases" (111, yesterday) from PCR testing and "newly reported probable cases" (25, yesterday) from antibody testing, and those are added together as 136 "newly reported cases today." And that's the number that data aggregator sites are using for the number of "new cases" each day in MA. Those time-shifted numbers could become very misleading as time goes on.
Yeah, exactly. I self-quarantined as if my test result had been positive anyhow. (Why not, it's not like I was feeling up to going out.) The only difference is, if my test had been positive, my wife would have also been quarantined and tested as a recent contact of mine. She had no symptoms at that point (or since), and went to work. All water under the bridge now, in any case.
I think MA has contact tracing going, so if my test had been positive there would have been follow up. It would have been easy enough, in my case.
