Claire Michel competed in the women’s triathlon on Wednesday and finished 38th.
A Belgian team source told Sport that, contrary to reports in Belgian media, the 35-year-old had not developed E. coli.
They also stated that they could not be positive of a link between Michel’s illness and the River Seine, where the swimming leg is held.
Prior to and during Paris 2024, the Seine’s poor water quality was a key topic of discussion.
It delayed the men’s triathlon by a day, while the practice swim for the mixed relay was postponed on Sunday for the second day in a row.
The mixed relay event began as scheduled on Monday morning, despite requests from teams to postpone the competition to allow for extra athlete preparation time.
According to a joint statement released by World Triathlon and Paris 2024, “the latest test results confirm that Seine water-quality levels at the triathlon venue have improved in recent hours, with forward-looking analysis indicating that water quality will be within the levels acceptable by World Triathlon.”
On Saturday, the Swiss team announced that their athlete Adrien Briffod, who competed in the men’s race, had a stomach virus and would not participate in the mixed relay.
The Belgian Olympic Committee (COIB) stated that Michel visited the polyclinic at the Olympic village but was not sent to the hospital.
