Ann: Cellmid's Shipment of SARS-CoV-2 Tests Received, page-277

"You’ve got antibodies...great son, go back to work."
Unfortunately it doesnt end there.
"Can you give me a list of all the people you have been in contact with recently, we will need to test all them as well to see if they are carriers.
Somebody gave it to you and you got off lightly, produced antibodies readily and have become immune, hopefully . Others might not be so lucky"

Six months later they are still testing all the possible connections to that small group of workers that cleared the work hurdle by having antibodies

The task is phenomenal
