An alternate on the star-studded United States women's gymnastics team has tested positive for COVID-19 in an Olympic training camp in Japan.
Olympic champion Simone Biles was not affected, nor were any of the other favourites to win the team gold, but another alternate was placed into isolation because of contact tracing, USA Gymnastics said on Monday.
"One of the replacement athletes for the women's artistic gymnastics team received a positive COVID test on Sunday, July 18.
"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 statement said. "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."
US officials said the test took place when the team was training just outside Tokyo in Inzai City.
The positive test was the latest in a growing line of daily reports of athletes and others testing positive at the pandemic-delayed Olympics.
The four alternates - Leanne Wong, Kayla DiCello, Emma Malabuyo and Kara Eaker - traveled to Japan with the six-woman US delegation of Biles, Jordan Chiles, Grace McCallum, Sunisa Lee, MyKayla Skinner and Jade Carey.
The alternates are rooming and training together. While they have been traveling to training along with the actual team, they have been split into groups, with the team working on one apparatus while the alternates work on another.
The US women's team dealt with what USA Gymnastics called a "false positive" over the weekend for an unidentified athlete but the ensuing test results for the athlete were negative, according to the organisation.
Biles, who is also the world champion, and the rest of the regular team have been vaccinated.
The women's gymnastic team begins competing on Sunday.
