“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 Sunday that organizers will work to ensure “everything is perfect” for athletes waiting to be released. Han Zirong of the Beijing Organizing Committee also noted that athletes who test positive will now be able to order food from the Olympic Village and have it delivered to their isolation rooms.

As part of China’s efforts to prevent the virus from spreading during the Games, everyone in the so-called Olympic bubble has to take daily PCR tests. Those who are confirmed to be positive go to an isolation facility until they’re cleared for discharge, either through tests showing they’re negative or a review by a panel of medical experts.

Dubi’s comments came after complaints about the hotels where athletes must isolate. The German delegation called the situation “unreasonable” and said rooms should be bigger and cleaner after Eric Frenzel, a three-time gold medalist in Nordic combined, tested positive.

So far, organizers say 363 people inside the Olympic bubble have tested positive for COVID-19. In addition to athletes, the figure includes media and team officials.
