@migizii-- Not necessarily @migizii, I haven't heard anything either. I think that this will most likely be a process and not an event at this time. It just started so let's wait a bit and see what happens, ok?

migizii - I think @ihatediabetes rapid response was due to the facts that she lives in one of the "targeted areas" for testing - large metro area with a clinic just beginning their trial, and with her disabled son, she is out and about in the community often.

Nerd Alert! The following is a description of how to choose a sample population.
The statisticians tell the team the number of each "type" of subject they need to enroll to get the valid sample, and they work outward from the center of their study area to enroll the numbers they need. Types can include age, ethnicity, gender, occupation, location, underlying conditions... History shows the nearer subjects are to the test location (for followup) the more likely they are to stay all the way through to the end.
Finally, if you are in an area with very little Covid, or you are self-isolating due to underlying conditions, you will be near the bottom of the list because they want people who will likely be exposed to the virus.
