Cross-correlation between daily wastewater signals (RPMF) and National Syndromic Surveillance Program ED visit rates for SARS-CoV-2, influenza, and respiratory syncytial virus (RSV) in Harris and El Paso Counties, Texas, June 2022–June 2024. A) Harris County, SARS-CoV-2. B) El Paso County, SARS-CoV-2. C) Harris County, influenza. D) El Paso County, influenza. E) Harris County, RSV. F) El Paso County, RSV. Wastewater RPMF time series were shifted from −21 to +21 days relative to National Syndromic Surveillance Program ED visits, with Pearson correlation coefficients calculated at each daily lag. Negative lags indicate wastewater signals leading clinical visits. ED, emergency department; RPMF, reads per million filtered.
