Sena je primerna za plavanje :
"Belgium announced it was dropping out of the race after one of its triathletes, Claire Michel, has fallen ill, its National Olympic Committee said in a statement. The statement did not specify Michel’s illness, which was reported days after she swam in the River Seine during the women’s triathlon on Wednesday.
The Swiss team, meanwhile, had to replace Adrien Briffod, who had to withdraw due to a gastrointestinal infection. Simon Westermann will replace him.
Swiss Olympic Chief Medical Officer Hanspeter Betschart noted that it is unclear if Briffod’s infection is related to the Seine’s water quality."
