This is just some stuff I'm observing and thinking about. I'll probably want to add to it later. Make of it what you will; I don't know myself how much of it is relevant to the way we should be guided.
USA 50 million +/- tests
Worldometer Corona virus USA says:
3,926,000 alleged positives. (Some were presumptive, we don't now how many)
1,982,000 currently active positives (about 1 person in 166.)
Testing records 7.8% positive overall, more than that recently. Regarding these, we can suspect that there is at least some bias toward positives among those people who choose to present themselves for testing.
These numbers indicate a case mortality rate of 3.7% (3.7% of the people who catch it will die and it will be attributed as the cause of their deaths.)
We hear reports that much of the recent upturn in cases is positives found among a much younger cohort than had been seen previously. We can suspect from media reports and our own observations that many adults under 30 seem to have been far less cautious than other groups. At the time it didn't seem as crazy as it is looking now, given that their group showed a very small percentage of infections in their group previously.
I heard a report earlier today that a substantial group -- I think it was 18 -- of infants had tested positive in one locale (I think I heard somewhere in Texas, but don't quote me.)
Anyway, my thoughts about that is that there are two possible explanations: either the virus has mutated, or; the test protocol in that locale was compromised in some way, because the very young were previously getting infected at a rate of 1 in 1000 or some other crazy number I could have made up (77% of statistics are made up.)
Still trying to find US figures, but in Great Britain, only 33% of the people who test positive have or ever develop symptoms. (Based upon reporting on July 7.)
