The organizers of the Tokyo 2020 Olympic and Paralympic Games estimate that there will be about seven Covid-19 cases per day among people involved in the event, Japanese public broadcaster NHK reported Saturday.

The estimate was presented at a Friday meeting of experts on anti-covid measures, and was prepared by the organizing committee and the Tokyo authorities based on the number of people who tested positive during a test event conducted in May.

The calculation is based on the participation of about 77,000 people, including athletes and personnel, although it does not take into account the administration of vaccines between them, so the real figures could be lower.
