Tracking epidemics at the population level through wastewater-based epidemiology



Throughout the world, wastewater is continually collected from human populations and conveyed to central locations for treatment and/or discharge. The chemical and biological features of wastewater contain insight into the disease state and behavior of a community.  This talk reports on the Yale COVID-19 wastewater project, where daily samples were collected from eight different wastewater treatment facilities representing 20 Connecticut towns and cities and covering a population of more than one million. Tracking SARS-CoV-2 concentrations in these treatment facilities during the COVID-19 pandemic and linking these concentrations to public health data demonstrate how wastewater-based epidemiology can be a rapid, cost-effective, and accurate measure of disease dynamics within a community.
