The trailing 7 day positivity rate for individuals newly tested edged up once again to 2.2%, the highest rate since the middle of June. However, this rate has remained constant for the past three days, perhaps indicating that the increases since the end of August might be stalling out. The overall positivity rate based on testing remains steady at 0.8%, driven by repeat testers, very few of whom are testing positive. Only 30% of tests over the past 7 days were given to individuals who haven’t been tested before.
However, the large increase in the number of repeat testers over the past month is slowing down (the widespread college testing programs are probably up to speed). The number of first time testers actually decreased from one week ago.

Hospitalization, case, and death statistics remain basically unchanged from a week or a month ago. One encouraging sign may be a small drop in the number of intubated patients, both in absolute terms and as a percentage of patients in the ICU.

I’ve added two new statistics to Table 3 so that confirmed cases and deaths can be separated from suspected cases and deaths.

Thank you for this!
Off topic a bit. Do you have any idea why MA tracks anti- body testing? I can understand their value if (a) they were highly accurate; and (b) there was large scale, free random testing.
But neither of those conditions apply. So what’s the point? …
