Association between weekly wastewater signals (RPMF) and weekly TX-APCD ED claims for SARS-CoV-2, influenza, and RSV in Harris and El Paso Counties, Texas, June 2022–June 2024. A–C) Harris County weekly trends in wastewater RPMF values versus TX-APCD ED visits for SARS-CoV-2 (A), influenza (B), and RSV (C). Solid lines represent TX-APCD claims; dashed lines represent RPMF data. D–F) Weekly RPMF values versus NSSP ED visits for SARS-CoV-2 (D), influenza (E), and RSV (F). Triangles and diamonds represent single-week observations. G–I) El Paso County interpolated daily time series of RPMF values versus TX-APCD ED visits for SARS-CoV-2 (G), influenza (H), and RSV (I). Solid lines represent TX-APCD claims; dashed lines represent RPMF data. J–L) Weekly RPMF values versus NSSP ED visits for (J) SARS-CoV-2, (K) influenza, and (L) RSV. Triangles and diamonds represent single-week observations. Corresponding Pearson correlation coefficients (r) and p values are shown. ED, emergency department; RPMF, reads per million filtered; TX-APCD, Texas All-Payer Claims Database.
