RIO DE JANEIRO—The waters where Olympians will compete in swimming and boating events next summer in South America’s first games are rife with human sewage and present a serious health risk for athletes, as well as for visitors to the iconic beaches of Rio de Janeiro.
An Associated Press investigation found dangerously high levels of viruses and bacteria from sewage in venues where athletes will compete in the 2016 Olympic and Paralympic water sports, though an Olympic official said Thursday there are no plans to press for authorities to monitor for viruses, which many experts consider the biggest problem.
In the first independent comprehensive testing for both viruses and bacteria at the Olympic sites, the AP conducted four rounds of tests starting in March. The results have alarmed international experts and dismayed competitors training in Rio, some of whom have already have fallen ill with fevers, vomiting, and diarrhea.
