Infectious diseases can spread through communities before all cases are identified through individual testing or hospital reports. To monitor these changes more broadly, health authorities are becoming interested in a method called wastewater-based epidemiology, or WBE. This approach examines sewage for viruses and other materials connected with disease. Since infected people may leave these signs in wastewater, samples from treatment plants can reveal changes in disease activity across a community.
