November 16, 2022: COVID Weekly Data Update

SARS-CoV-2 in Wastewater & Sludge

Monitoring of SARS-CoV-2 replicates in wastewater and sludge may provide a means of determining the degree to which the virus is circulating in a community.

Wastewater replicates are thought to indicate the amount of virus at that point in time, while sludge replicates are thought to indicate the amount of virus over the past seven days.

Home test kits were made available beginning in January of 2022 and have become a routine method for self-identifying COVID-positive individuals.  However, the results of these home test kits are not reported to local authorities and do not appear on the South Dakota Department of Health (SDDOH) dashboard.  Therefore, it’s not possible to determine the number of new cases.

As shown below, wastewater SARS-CoV-2 virus concentration correlates well with the number of new cases (samples from across the country).  As the use of home test kits increased, the relationship between the wastewater virus concentration and case data has become less clear. 

For the last several months, Brookings Municipal Utilities has been collaborating with USD to establish a baseline of SARS-CoV-2 replicates in the city wastewater and sludge.  Data last week showed an increase in the virus in both wastewater and sludge, indicating that the number of COVID cases in the city was likely increased.  This week the levels are back down.

Other sites in South Dakota that are being monitored can be found here.  If you click on the location you will see the trend graph for that location. 

Updated Bivalent Booster

Dr. Eric Topol briefly summarized available data on the updated bivalent boosters, noting that the majority of reports show added immune protection from the updated booster.  He also notes that more than 70% of Americans aged 65 years and older have not received this booster.  Now is the time to get your updated bivalent booster.
