US Rowing is reviewing details of illnesses that 11 athletes suffered while at the Rio 2016 Olympic venue for the World Junior Championships last week, a spokesperson said Monday.
U.S. rowers suffered stomach illnesses with reports of vomiting and diarrhea, according to The Associated Press, amid concerns about water quality at the open-water venues for the Olympics next year.
The site of the World Junior Championships, Rodrigo de Freitas Lake, is also the site of the Olympic rowing competition next year.
US Rowing did not announce the source of the illnesses. It has experienced illnesses during team travel on other trips to well-known destinations, including recently in Italy when six athletes out of 25 became ill.
