RIO DE JANEIRO (AP) -- Just days ahead of the Olympic Games the waterways of Rio de Janeiro are as filthy as ever, contaminated with raw human sewage teeming with dangerous viruses and bacteria, according to a 16-month-long study commissioned by The Associated Press.
Not only are some 1,400 athletes at risk of getting violently ill in water competitions, but the AP's tests indicate that tourists also face potentially serious health risks on the golden beaches of Ipanema and Copacabana.
The first results of the study published over a year ago showed viral levels at up to 1.7 million times what would be considered worrisome in the United States or Europe. At those concentrations, swimmers and athletes who ingest just three teaspoons of water are almost certain to be infected with viruses that can cause stomach and respiratory illnesses and more rarely heart and brain inflammation - although whether they actually fall ill depends on a series of factors including the strength of the individual's immune system.
Since the AP released the initial results last July, athletes have been taking elaborate precautions to prevent illnesses that could potentially knock them out of the competition, including preventatively taking antibiotics, bleaching oars and donning plastic suits and gloves in a bid to limit contact with the water.
But antibiotics combat bacterial infections, not viruses. And the AP investigation found that infectious adenovirus readings - tested with cell cultures and verified with molecular biology protocols - turned up at nearly 90 percent of the test sites over 16 months of testing.
The beaches even violate Rio state's own standards, which are much less stringent than those in California, many other U.S. states and beach-loving countries such as Australia and New Zealand. In Rio, beaches are considered unfit if bacterial tests turn up more than 2,500 fecal coliforms per 100 milliliters - more than six times higher than the upper limit in California. But Copacabana and Ipanema even violated those much higher limits on three separate occasions. The state environmental agency, INEA, did not respond to repeated requests for comment.
