China says virus infections certain in Olympics bubble

Chinese officials said Thursday they were ready for coronavirus outbreaks inside the Winter Olympics bubble, with plans in place to send symptomatic athletes to designated Beijing hospitals.

February's Olympics are set to be the most restrictive mass sporting event since the pandemic began, with international spectators banned and all participants required to stay inside a closed-loop system. 

"There will definitely be infections and there could be a chance of a small-scale cluster outbreak happening," said Beijing Olympics virus control official Huang Chun at a briefing, adding that the large number of people involved will have a "very high risk of transmission".

"There will be a certain number of positive cases" another organizing committee official, Han Zirong, said. "This is a high probability event."

China -- where Covid-19 was first detected -- has slowed new cases to a trickle, implementing a strict "zero-Covid" strategy involving tight border restrictions, targeted lockdowns, lengthy quarantines and population tracing technology.

Even a single case can lead to a swift imposition of curbs, and officials deemed to have failed at controlling Covid-19 are often sacked.

Hosting a high number of foreigners for the Winter Olympics remains a high-risk endeavor for China's leaders. 

In addition to mandatory vaccinations before landing in China, all athletes and personnel inside the bubble must undergo daily virus testing and health monitoring.

Officials strongly encouraged athletes to get a booster jab due to the global spread of the Omicron variant. 

They also provided guidelines for the limited number of domestic spectators.

"We encourage clapping to encourage athletes and don't recommend (spectators) take their masks off to sing or shout," Han said.

Athletes who test positive for the virus cannot participate in the Games.
