The Paris Olympics has been hit by a health scare as multiple athletes fall seriously ill after competing in the triathlon events held in the Seine River. Belgium has been forced to pull out of the mixed triathlon relay after athlete Claire Michel was hospitalized with an E. coli infection. Swiss Triathlete Also AffectedSwiss triathlete Adrien Briffod has also fallen seriously ill following the men’s individual triathlon event. This follows concerns over the water quality in the Seine, which had previously led to the postponement of the men’s event. Despite the French government’s $1.5 billion effort to clean up the Seine River, which had been banned for swimming since 1923 due to pollution, the water quality has not met expectations.
