Sept 22, 2021: COVID Weekly Update

This pandemic is not done with us.  Based on actions I’ve seen, and what people seem to think, it would be safe to say that you can look at the worst-case scenario in the projections given below.  Based on that scenario, it is estimated that 476 more people in South Dakota will die before January 1st.

The Institute for Health Metrics and Evaluation (IHME) at the University of Washington updated its South Dakota projections last Wednesday 9/15/21) (

The following are the estimated peaks for the current wave: 

Long-COVID in Children:

The following is from a review article published on 9/16/21 in The Pediatric Infectious Disease Journal (

These investigators reviewed 14 studies that reported persistent symptoms following COVID infection in children & adolescents.  The authors noted that only five studies had a control group, and two of these five studies found no difference between the prevalence of long-term symptoms among children with and without COVID.  

The author’s conclusions were:

  • Almost all the studies to date have major limitations. 
  • Evidence for long COVID in children & adolescents is limited.
  • Given the large number of children & adolescents infected with SARS-CoV-2, the impact of even a low prevalence of persisting symptoms will be considerable.
  • The majority of studies found that symptoms do not persist longer than 12 weeks.
  • There is a scarcity of studies of long COVID & there are limitations of those reported.  Therefore, the true incidence of this syndrome in children & adolescents remains uncertain.  

Weekly Updates

A few highlights:  

  • 46% of Brookings cases this past week have been in children under 20 years of age compared to 28% statewide.
  • 1% of South Dakota K-12 students have tested positive for COVID since August 8th(1,337/135,984).
  • Out of the counties with the top ten most populated cities, Brookings County currently has the third-highest number of new cases per week per 100,000 population (371/100,000).  
  • The CDC recommends universal indoor masking for any county with substantial or high spread, defined as more than 50 new cases per week per 100,000 population.  All counties with the ten most populated cities have weekly rates greater than 100 new cases/100,000 population.

Brookings County (highest level of spread)

  • 4,838 total cases:  130 new cases this week (high spread) vs. 126 in the previous week:
    • 60 (46%) were under 20 years of age (vs. 40% last week)
    • 37 (28%) were 20-39 years (vs. 35% last week)
    • 15 (12%) were 40-59 years (vs. 16% last week)
    • 18 (14%) were 60 years or older (vs. 9% last week)
  • Since August 25th, the largest increases in the percentage of cases have been in the 0-9 year (31% increase) and 10-19 year (15% increase) age groups.  The largest increase in the number of cases has been in the 20-29 year age group (n=111).
  • 279 active cases (233 last week)
  • Test positivity (PCR) this past week was 11% compared to 11% last week.  Ideally, you want this below 5%, and the lower, the better.  A high percentage indicates there are likely many more cases out there – get tested if you have been exposed or have symptoms.
  • There were 2 new hospital admissions among Brookings County residents in the past week vs. 0 in the previous week.  Brookings Hospital currently has 1 COVID hospitalized patient.  In Sioux Falls, Avera has 24 COVID-occupied beds (13 ICU) and Sanford has 49 (17 ICU).
  • There were no new deaths reported among Brookings County residents this past week.  
  • The percentage of people vaccinated did not increase much this past week, with 44% of Brookings County fully vaccinated vs. 44% of South Dakotans (similar percentages as last week).

South Dakota (highest level of spread)

  • 141,745 cases: 2,885 new cases this week vs. 3,322 in the previous week:
    • 822 (28%) were under 20 years of age (vs. 30% last week)
    • 853 (30%) were 20-39 years (vs. 29% last week)
    • 715 (25%) were 40-59 years (vs. 24% last week)
    • 495 (17%) were 60 years or older (vs. 17% last week)
  • 7,714 active cases (7,364 last week)
  • Test positivity (PCR) this past week was 14% compared to 14% last week.  Ideally, you want this below 5%, and the lower, the better.  
  • 144 people were admitted to in-state hospitals this week vs. 124 last week:  
    • 4 (3%) were aged less than 20 years (vs. 3% last week) – NOTE:  All four patients were less than 10 years of age
    • 16 (11%) were 20-39 years (vs. 11% last week)
    • 38 (26%) were 40-59 years (vs. 25% last week)
    • 86 (60%) were 60 years of age and older (vs. 61% last week)
  • 226 people currently hospitalized vs. 204 hospitalized last week (65 currently in the ICU vs. 58 last week)
  • 2,109 deaths:  16 deaths reported this week vs. 16 in the previous week:  
    • 1 was 20-39 years
    • 3 were 40-59 years
    • 12 were 60 years of age and older

  • 4.72 million deaths: 60,011 deaths this week vs. 63,198 in the previous week 

Be kind to yourself & others, especially health care workers who are very tired of all of this – get vaccinated, wear a mask when indoors, socially distance, avoid crowds and practice good personal hygiene.
