A total of 21 new Covid-19 infections have been found among Olympic Games-related personnel, down from 55 a day earlier, Games organisers said ahead of the opening ceremony.

Hours before the Winter Olympics officially get underway, the total number of confirmed cases among Games participants since Jan 23 was 308, among them six unnamed athletes of the German Olympic team, who tested positive after their arrival on Thursday.

They have now gone into isolation and are undergoing further PCR tests, the German team said.
