The Tokyo 2020 Olympic and Paralympic Games were held in the summer of 2021, despite concerns about SARS-CoV-2 transmission.1,2 We assessed SARS-CoV-2 infections detected in close contacts of confirmed cases within the Olympic and Paralympic Village.
All participants (such as athletes, coaches, medical staff, physical therapists, and Paralympic companions) were required to test negative for SARS-CoV-2 prior to departure from their country of origin. COVID-19 vaccination was recommended but not mandatory. All individuals were tested with a SARS-CoV-2 saliva antigen test on airport arrival in Japan and were moved to the Village immediately if results were negative.
