11. There must be some way to test for the presence of the antibody.

Two negative tests as confirmation of recovery from the virus should be accompanied by a test for the presence of the antibody.

I think we don't know enough now to know how long immunity generally lasts. I know there was a report about a fairly rapid reinfection in a recovered person, but it's unclear to me how common that is. There may have been reason unique to the person that explains why the antibody didn't "last" in them.

Part of research will be testing recovered for presence of the antibody over the course of many months to determine how long it generally "lasts."

Whatever we know, or learn about how long immunity lasts, and the possibility of it lasting only a short time, must be conveyed to every person deemed "recovered." That should help limit any "invincible" feeling they might walk away with.
