“If any athlete tests positive for COVID-19, he/she will be reported and managed according to relevant requirements,” the media team told CNN on Saturday.

The media team did not say whether any other Olympic personnel outside of athletes had tested positive. CNN has followed up requesting this information but has not yet heard back.

As of Friday, more than 2,000 participants have arrived in Beijing, including athletes, officials, members of the IOC and media, according to the official app for the Beijing Winter Games.

To limit the spread of infection, Beijing is sealing the entire Games inside what authorities have called a “closed loop system” — a bubble completely cut off from the rest of the city. Thousands of Chinese volunteers and staff have already spent days, if not weeks, inside the closed loop.
