Main Article

Figure 3

The probability of a positive SARS-CoV-2 clinical test by long-term care facility as a function of the average weekly wastewater SARS-CoV-2 concentration (genome copies/mL) at that facility, Kentucky, USA, March 2021‒February 2022. Facility-specific curves are A–F; the final curve is a composite curve that uses data from all 6 facilities. Vertical blue lines at 400 and 600 gc/mL serve as reference points to identify site-specific wastewater signal thresholds when the probably of detecting a SARS-CoV-2 case is >0.5.
