I've been monitoring the
SD Dept. of Health for the last two weeks to see if any sort of breakout would occur there.
Here is the data I have so far. These numbers are the total numbers of coronavirus cases taken directly from the website above. The three counties are:
1. Meade County, where Sturgis is (Sturgis is way over on the western border of Meade Co.)
2. Lawrence Co., just west of Meade
3. Pennington Co., south of Meade and home to Rapid City and Mount Rushmore

Those are the total number of cases up through that date. The numbers you typically see on charts are new cases per day. To get that, we subtract each row from the prior row. Note that this means we lose one row.

There's definitely been an uptick in Meade County since Aug. 16, but how much? Doesn't look like too much until you get today, right?
No. Those are total numbers. We need to look at the per-capita numbers there. Multiplying each county's new daily totals by 1 million and dividing by their respective populations gives us the same per-capita numbers that you see in places such as
here. Those per capita numbers are:

The decimals are annoying, so I'm just going to focus on the Meade County column, because that's where Sturgis is anyway.

For comparison, at its peak of the first wave, Florida was suffering over 500 new daily cases per million people. New York state briefly got up there, too.
But wait, it gets better. Meade County had an estimated 2018 population of 28,294, and Sturgis had an estimated 2019 population of 6,922. Giving Sturgis a head start of a year actually amplifies the point I am about to make: Sturgis has a little less than a fourth of Meade County's population. So if at least half of Meade's cases are occurring in Sturgis, which is a very conservative assumption, then as of today, nearly 1 in 1000 people in Sturgis are getting infected
per day.
Congratulations, Sturgis. You've just become the latest hotspot. Exactly as the experts predicted, exactly as the deniers denied.
