With the Rio de Janeiro Olympics a little over a year away, an investigation has shown that not a single venue is safe because of extreme water pollution that endangers their health and possibly that of spectators.
To win the Olympic bid, Brazilian officials promised to clean up its waters, but they now say they cannot keep that pledge. Fish still cover beaches and a stench hangs in the air. Nearly 1,400 athletes will sail in water near Marina da Gloria, swim just off Copacabana beach and canoe and row on Rodrigo de Freitas Lake and they are “almost certain to come into contact with disease-causing viruses that in some tests measured up to 1.7 million times the level of what would be considered hazardous on a Southern California beach,” the AP story says.
Instead, the test results found high counts of active and infectious human adenoviruses, which multiply in the intestinal and respiratory tracts of people. These are viruses that are known to cause respiratory and digestive illnesses, including explosive diarrhea and vomiting, but can also lead to more serious heart, brain and other diseases.The concentrations of the viruses in all tests were roughly equivalent to that seen in raw sewage — even at one of the least-polluted areas tested, the Copacabana Beach, where marathon and triathlon swimming will take place and where many of the expected 350,000 foreign tourists may take a dip.“Everybody runs the risk of infection in these polluted waters,” said Dr. Carlos Terra, a hepatologist and head of a Rio-based association of doctors specializing in the research and treatment of liver diseases.
Austrian sailor David Hussl told the AP that he and his teammates are being careful, washing their faces with bottled water when they are splashed and showering when they come ashore. And Hussl has still gotten sick because viruses can enter the body through the mouth, eyes, any orifice or cut.
“I’ve had high temperatures and problems with my stomach,” he said. “It’s always one day completely in bed and then usually not sailing for two or three days.”
