[youtube]fXzECpf4lEw[/youtube] 08/2015 The World Health Organization has asked the International Olympic Committee to run new tests on Rio’s waterways after an Associated Press investigation declared them potentially dangerous to athletes because of their high pollution levels. The request came in conjunction with an announcement from the governing body of world sailing that said it, too, would do its own independent testing. At the center of the controversy is the virus load carried in the waterways in which swimmers, rowers, canoeists, sailors and triathletes will compete. According to the AP investigation, pollution from raw sewage has made those levels dangerously high and some athletes who have been training in Rio have experienced bouts of fever, vomiting and diarrhea.
