Abstract
Several studies have demonstrated that wastewater surveillance can be used to monitor SARS-CoV-2 incidence.1-3 This surveillance intends to overcome the limitations of traditional surveillance indicators,4 such as the number of positive tests, which depends on test availability and indications, or COVID-19–related hospitalizations, which occur weeks after the spread of SARS-CoV-2 and do not include mild or asymptomatic cases. This study evaluated the association between SARS-CoV-2 load in urban wastewater and surveillance indicators of infection prevalence and severity in Milan, Italy.Keywords
