In this study, the authors wanted to examine the association between clinically reported cases and viral loads in wastewater. They correlated the results of 360 samples collected from manholes in 7 distinct areas of the Village with confirmed COVID-19 cases obtained from the Organizing Committee, and with data of close contacts tests from a previous report.

The researchers found that SARS-CoV-2 was present in 151 wastewater samples—53 from the Olympics and 98 from the Paralympics. The number of confirmed cases was also higher in the Paralympics. The strongest correlation between SARS-CoV-2 RNA load in wastewater and the presence of clinical positive areas was found in areas that had maximum viral loads in wastewater in a three-day span.

The study suggests that WBE and clinical tests are complementary and that the testing strategy played a role in preventing COVID-19 clusters in the Village. This study of one of the world's largest mass gatherings provides novel evidence on the implementation and use of wastewater-based epidemiology in communities where all members undergo daily testing, and could be used to trace and control COVID-19 clusters in the future.
