Olympic organisers say they're addressing complaints about isolation conditions for athletes who test positive for the coronavirus and are working to ensure they have clean rooms, better food and access to training equipment and the internet.

"These are exactly the kind of things we have to address. It's a duty. It's a responsibility. We have to make sure that the expectations are met," said Christophe Dubi, the International Olympic Committee's executive director for the games.

Dubi said that organisers will work to ensure everything is perfect for athletes waiting to be released.
