An alternate on the US women's gymnastics team has tested positive for COVID-19

• An alternate on the US women's gymnastics team has tested positive for COVID-19.
• Kara Eaker's coach confirmed her as the team's positive test to a television reporter based in Des Moines, Idaho
• She tested positive for COVID-19 less than a week before the opening ceremony for the Tokyo Olympics.

An alternate on the US women's gymnastics team tested positive for COVID-19, USA Gymnastics said on Monday.

The organization didn't initially identify the gymnast, but Kara Eaker's coach, Al Fong, confirmed her as the team's positive test to a television reporter based in Des Moines, Idaho. The 18-year-old athlete is set to be held in isolation for eight to 14 days, reporter Justin Surrency said on Twitter.

Eaker previously told Kansas City's KSHB she had been vaccinated against COVD-19, the station reported Monday.

The alternate tested positive for COVID-19 on Sunday, less than a week before the opening ceremony for the Tokyo Olympics.

"After reviewing the implemented COVID protocols with members of the delegation, the local government determined that the affected replacement athlete and one other replacement athlete would be subject to additional quarantine restrictions," the USAG told the Associated Press in a statement. "Accordingly, on Monday, the Olympic athletes moved to separate lodging accommodations and a separate training facility, as originally planned, and will continue their preparation for the Games. The entire delegation continues to be vigilant and will maintain strict protocols while they are in Tokyo."

News of the alternate's positive test came after three athletes in the Olympic Village, including two South African men's soccer players and a Czech beach volleyball player, were also confirmed positive cases. American tennis star Coco Gauff announced late Sunday that she was dropping out of the games after a positive COVID-19 test.

The athletes are among at least 55 people associated with the games, including employees and members of the media, who tested positive for COVID-19 as of July 18, Insider's Julie Gerstein previously reported.

The Olympics are set to begin on Friday, July 23.
