The Judge stated that there were 12 x=cases, assumed confirmed by testing. If there were 12 confirmed cases, that means they likely sought care and were tested as a result of symptoms.
Logic dictates that of course there are quite a few more people who have been exposed, had minor or no symptoms or had serious symptoms but did not seek medical help, lets say for every 1 confirmed case at hospital, there were five more who got mildly ill, 5 more who had no symptoms and maybe 2 who had pretty serious illness but did not seek medical help, so for every one confirmed, lets say 13 more also had been infected etc. So, if my SWAG ( more science than the US Dept of Health I think) is anywhere near accurate, then 12 times 12 means 144 at that time could have been infected or suck of covid19 to some degree not including those who wen to hospital. Now, roll that up over time, say, each week since the first confirmed case, that ratio of 12 to 144 carried on, some in a few weeks the county could have possibly have had 500 exposed, but only 12 confirmed.
Of course, my math is just conjecture. this is why Iceland study of widespread testing makes sense while modeling in a math program means nothing but fear, overreaction and useless and harmful political maneuverings.
Lets test 10 percent of population randomly in every area, say a million tests. I bet the rate of antibodies shows that many many more of us have had covid19 and survived, thinking we had a bug or a cold or maybe flu.
Then run the numbers based on what we know from CDC reporting etc and come up with a real risk, then proceed to hang the fools advising our POTUS and get America turning and burning again. As it should have been since Marches Madness.
Sorry for the typos, cell phones scuk for accuracie.
If you're right in your speculated number, only 2/3 of 1% of the county's population has been exposed so far, and there's still another 76,000 of the roughly 76,500 population of his county that haven't been exposed yet. It's going to be an awfully long, sustained slowdown to the economy if we're going to let the virus works it's way though the population at less than 1% per month. Of course, it could also be that you're low on your guess, and there may have already been many thousands in that county that have been exposed with minimal effect.
