Oct 27, 2021: COVID Data Weekly Update

Mortality data for South Dakota through August of 2021 have been updated on the SDDOH website (https://doh.sd.gov/documents/statistics/Mortality-Report-2021-Provisional.pdf).

As shown above, the number of deaths per 100,000 population in 2020 and 2021 follow a similar pattern as 2010-2019 during the months of February through June.  The number of total deaths during the months of January and August of 2021 are higher than number of total deaths observed in previous years.  In 2020, the number of deaths exceeded the highest number of deaths previously observed for the months of August through December.
The graph above shows the number of deaths by cause for the months of January through August for each year since 2011 (deaths in the months of September through December are not included for any year).  The large number of COVID deaths in 2020 will become more obvious the further in the year we get since most of those deaths were during the end of 2020.

Brookings School District started back to classes on August 25th and SDSU started back on August 23rd.  I thought it would be interesting to compare the number of new cases for the nine weeks since August 25th with the nine weeks prior to August 25th (6/16/21).  As shown below, the number of new cases increased in each age group, but some age groups increased more than others.  It must be acknowledged that Brookings School District is not the only school within the county.

Now for the Weekly Updates

A few notes:

  • The downward trend in cases in South Dakota and Brookings County seems to be over, with cases this past week being in the highest level of community spread and increasing slightly. 

Brookings County (highest level of spread)

  • 5,123 total cases:  51 new cases this week vs. 43 in the previous week.  The 20-39 year age group had the majority of cases this past week.  Of the new cases this past week:
    • 18% were under 20 years of age (vs. 7% last week)
    • 41% were 20-39 years (vs. 23% last week)
    • 18% were 40-59 years (vs. 30% last week)
    • 23% were 60 years or older (vs. 40% last week)
  • Since September 29th, the largest percentage increase in cases has been in the 0-9 year (8% increase, n=20) age group. However, the largest increase in cases has been in both the 20-29 and 30-39 year age groups (n=38 and n=35, respectively).
  • 121 active cases (128 last week)
  • Test positivity (PCR) this past week was 5.3% compared to 4.0% last week – this is good.  Ideally, you want this below 5%, and the lower, the better.  A high percentage indicates there are likely many more cases out there – get
  • 47% of both Brookings County residents and South Dakota residents are fully vaccinated (total population) – same as last week. 

South Dakota (highest level of spread)

  • 153,774 cases: 2,220 new cases this week vs. 2,217 in the previous week.  Of the new cases this past week:

  • 5,464 active cases (5,723 last week)
  • Test positivity (PCR) this past week was 13.0% compared to 12.9% the previous week.  Ideally, you want this below 5%, and the lower, the better.

    • 1 was 20-39 years
