Belgian athlete Claire Michel has been hospitalized for three days following a swim in the Seine River last week, and other athletes have reported health issues, including one who allegedly vomited ten times. While recent water tests show bacteria levels within acceptable limits, concerns persist as no direct link between the water quality and the illnesses has been confirmed. This uncertainty has raised doubts about holding events in the river. Despite assurances from Paris 2024 Olympic organizers that investments are being made to improve water safety, athletes and residents remain cautious.
