CDC says nearly 67% of U.S. counties have substantial, high COVID-19 transmission

12. Yeah, I did some data gathering and math, and concluded

that they gave Cameron ( pop. 4339 [1] ) a "HIGH" rating for its 12.9% positivity rate [2]. The CDC map says the number of cases per 100k in the past week is "not available" [2]

Without going in more detail (here's where the math and other data gets used), that positivity rate appears to be based on just ONE or TWO actual cases in the past week. So yup, not exactly a Guinness World Book of Records for largest sample size, nor likely to ever be a textbook case illustrating the power of the Law of Large Numbers

(For anyone following along, Cameron is the bright red county approx. in the middle of the state on an East-West axis, and near the New York state border.)
