August 24, 2022: COVID Weekly Data Update

COVID-19 and Wastewater Surveillance

Because of the use of COVID-19 home test kits, the number of new cases per week is no longer adequate for monitoring the presence of SARS-CoV-2 in a community since the results of the home kits are not reported to public health officials. 

Methods have been developed to track the presence of SARS-CoV-2 in a community by measuring wastewater samples and may provide an early warning of COVID-19’s spread.

Wastewater samples are collected from sewer systems and then the SARS-CoV-2 genetic material is measured and the data are normalized to take into account differences between sewer systems, such as the wastewater flow rate and the number of people served by a sewer system.

Communities voluntarily report wastewater data to the CDC and the CDC generates maps based on these data.  The CDC data can be presented with and without “new sites,” which are sites that have reported less than 10 samples, which is not enough samples to meaningfully compare levels over time (see CDC website).

The following maps are provided by the CDC and do not include new sites, only include those sites that began collecting data after December 1, 2021, and represent the period of August 5 – August 19, 2022:

Current virus levels in wastewater:

Percent change in the last 15 days:

Percent of wastewater samples with detectable virus in the last 15 days:

Although South Dakota does not currently contribute very many samples to this analysis, it is possible to see places in the US that currently have high amounts of virus in their wastewater; in particular, Nebraska and Illinois.
