Because SARS-CoV-2 transmission was a major concern during the Tokyo 2020 Olympic and Paralympic Games, wastewater surveillance,1 mandatory daily screenings with antigen saliva tests,2 and polymerase chain reaction (PCR) tests for close contacts of individuals with confirmed cases3 were conducted in the Olympic and Paralympic Village. In this cross-sectional study, we investigated the association of SARS-CoV-2 load in wastewater with the numbers of confirmed COVID-19 cases and tests for close contacts.
