Remember that the decrease in the number of new cases is despite a dramatic increase in testing. We are now testing more than two times as many people every day then we did back in the beginning of April. And yet the number of new cases is less than half of what we had a few weeks ago.
You are absolutely correct. If you recall and one of the Corona briefings Dr. Birx and Fauci stated that then the numbers consistently fall below 10% (+) we are on the right track. In Florida, all counties are reporting less than 10% (+) with most counties well under 5%. This means one of two things — we are done with this because
1. The disease is being overhyped
2. It has spread all the way through and we have some degree of herd immunity
Given all the anecdotal data of people who are likely to have had it plus the experience of seeing critically ill patients with (-) influenza swabs in January and February, and now with the news that Ohio had cases in early January, I would bet on the development of herd immunity plus the fizzling of the virus due to mutations making it weaker combined with the warmer weather coming.
Common things are common, and this would be the explanation that we have seen over and over again for the last 100 years.
