TOKYO—An alternate on the 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 favorites to win the team gold, but another alternate was placed into isolation because of contact tracing, USA Gymnastics said Monday.
