USA Swim Team Hit By Acute Gastroenteritis Outbreak At World Championships

The U.S.A. Swimming Team at the 2025 World Aquatics Championships in Singapore has been hit with an acute gastroenteritis outbreak, causing disruptions in their performance. The exact extent of the outbreak is unclear, with notable absences from different races among team members. Torri Huske, a gold medalist at the 2024 Paris Olympics, did not compete in the women’s 100m butterfly event, while Claire Weinstein, another Olympian, was absent from the women’s 400m freestyle race.

Speculation surrounds whether these absences were due to acute gastroenteritis, as USA Swimming has not provided detailed information on the outbreak. However, Nikki Warner, senior communications director for USA Swimming, mentioned that the team’s medical staff is actively treating affected individuals and advising on preventive measures.

Acute gastroenteritis involves inflammation of the stomach and intestines, leading to symptoms such as nausea, vomiting, abdominal cramps, and diarrhea. It can be caused by viral infections like norovirus, bacterial pathogens such as Salmonella, parasites like Giardia, or exposure to harmful substances like alcohol or medications.

Preventing acute gastroenteritis involves practicing good hygiene, cleaning surfaces, avoiding sharing items with infected individuals, and being cautious with food sources. Treatment for infectious gastroenteritis typically involves rest and hydration, while severe cases may require hospitalization and additional interventions.

It remains to be seen how long it will take for the affected U.S. swimmers to recover fully and return to competition. With proper care and time, they should be able to overcome the effects of acute gastroenteritis and resume their pursuit of success in the pool.
