Fig. 2 — Sampled seroprevalence and wastewater concentrations of SARS-CoV-2 in Jefferson County (Panels A–B) and sewersheds (Panels C–H) at specific dates between 2020 and 2021. Sewershed areas are stratified as MSD1 (C–D), MSD2 (E–F), and MSD3–5 (G–H). Left panels show changes in the SARS-CoV-2 (N1) concentration in wastewater (indicated by discrete yellow dots; solid black lines represent the model-estimated prevalence; and the shaded area corresponds to 95 % credible bounds). Right panels show the percent seroprevalence in study participants (represented by black dots indicating sample-size weighted observations; the green line is the best fit of the model median prediction; and the shaded area corresponds to the 95 % credible bounds).
