Last week Barb, her daughter Maddy, and I all had blood drawn for testing of antibodies to SARS-CoV-2.
All results came back negative. We were pretty certain Barb and I would be negative. But Maddy was working in Brooklyn, New York until late March and told us horror stories of how tight people were packed on the subways. So, when she came home she was in quarantine for a while. But we thought maybe she picked it up without symptoms. Nope.
