Irish swimmer Daniel Wiffen, who won gold and bronze medals at the Paris 2024 Olympics, was rushed to the hospital due to a stomach bug, preventing him from serving as Team Ireland's flag bearer at the Closing Ceremony. He finished 18th in the 10km marathon swim in the River Seine, an event that faced scrutiny over water quality amid reports of illnesses affecting other athletes. Wiffen expressed his disappointment on social media, thanking supporters and wishing to be well enough to participate in a homecoming event in Dublin. The Seine's water quality issues have raised concerns, as at least three athletes reported illnesses after competing in the triathlon events held in the river. Despite these challenges, Wiffen reflected on achieving his Olympic dreams and expressed gratitude to his support team. Paris 2024 organizers maintain that the water quality was within acceptable levels during competition times.
