SARS-CoV-2 Titers in Wastewater Are Higher than Expected from Clinically Confirmed Cases
Category: Article Summary
Topic: Transmission
- Wu et al. tested wastewater collected at a major urban treatment facility in Massachusetts from March 18 to 25, 2020 and observed significantly higher SARS-CoV-2 titers (57 to 303 copies per mL of sewage) than expected based on number of clinically confirmed cases at the time. The investigators suggest that wastewater-based surveillance could help inform relaxing of lockdown and quarantine efforts.
