Trends in wastewater SARS-CoV-2 viral load in the 14 sewersheds in NYC. The map in (A) shows 14 sewersheds (delineated by color) and 42 United Hospital Fund neighborhoods (delineated by lines). Dots show the per-capita SARS-CoV-2 viral load in each of the 14 sewersheds (right y-axis, in million copies per day per population by RT-qPCR; color coded per the legend) during the 2nd wave (B), Delta wave (C), and Omicron period (D). For comparison, we overlay the citywide estimates of infection prevalence (left y-axis; blue line鈥�=鈥塵edian; darker blue area鈥�=鈥�50% CI and lighter blue area鈥�=鈥�95% CI)
