Association between hospital‐acquired (HA) COVID‐19 cases and wastewater SARS‐CoV‐2 signal from hospitals. Heatmap for the Spearman analysis between cases of COVID‐19 attributed to Delta, Omicron VOC and/or all active cases and wastewater signal obtained with either the N1 assay or N200 assay or VOCs specific assays (i.e., R203M [Delta] or R203K/G204R [Omicron]) from five hospital locations: Hospital 1, Hospital 2, Hospital 3A, Hospital 3B; and Hospital 3C. HA cases occurring ± 2 days were compared to wastewater signals. Spearman r value is only shown for those analysis when p < 0.05. VOC, variants of concern
