A US Olympic athlete has tested positive for Covid-19 in Tokyo, according to the US Olympic Committee.
It did not reveal the identity of the athlete.
"Of the 1,038 US Olympic delegates in Japan on July 24, one Covid test was confirmed positive based on daily results," the committee said in a tweet on Saturday night.
The committee announced on Friday that it would report daily positive cases from US Olympic athletes in Tokyo.
"Additionally, of the nearly 60% of the US Olympic delegation who was expected to travel to Japan from July 1-23, six US athletes and officials tested positive for Covid-19 as part of the rigorous pre-departure testing process and were not permitted to travel," the committee said Friday.
"The remaining 40% of the US delegation for the Olympic Games will arrive in Tokyo periodically over the coming weeks as pre-departure testing and monitoring continues," it added.
