RIO DE JANEIRO (Associated Press) – Olympic sailor Erik Heil floated a novel idea to protect himself from the sewage-infested waters he and other athletes will compete in during next year's games: He'd wear plastic overalls and peel them off when he was safely past the contaminated waters nearest shore.

Heil, 26, was treated at a Berlin hospital for MRSA, a flesh-eating bacteria, shortly after sailing in an Olympic test event in Rio in August. But his strategy to avoid a repeat infection won't limit his risk.

A new round of testing by The Associated Press shows the city's Olympic waterways are as rife with pathogens far offshore as they are nearer land, where raw sewage flows into them from fetid rivers and storm drains. That means there is no dilution factor in the bay or lagoon where events will take place and no less risk to the health of athletes like sailors competing farther from the shore.

"Those virus levels are widespread. It's not just along the shoreline but it's elsewhere in the water, therefore it's going to increase the exposure of the people who come into contact with those waters," said Kristina Mena, an expert in waterborne viruses and an associate professor of public health at the University of Texas Health Science Center at Houston. "We're talking about an extreme environment, where the pollution is so high that exposure is imminent and the chance of infection very likely."

In July, the AP reported that its first round of tests showed disease-causing viruses directly linked to human sewage at levels up to 1.7 million times what would be considered highly alarming in the U.S. or Europe. Experts said athletes were competing in the viral equivalent of raw sewage and exposure to dangerous health risks almost certain. […]

"The levels of viruses are so high in these Brazilian waters that if we saw those levels here in the United States on beaches, officials would likely close those beaches," Mena said. […]

As a result, none of the venues are fit for swimmers or boaters, she said. Athletes who ingest three teaspoons of water have a 99 percent chance of being infected by viruses. […]

But the high levels of sewage-linked pathogens found in the offshore sailing courses "show that these viruses don't just come from the marina -- there are many, many points where sewage enters the bay," Spilki, the Brazilian expert, said. "These pathogens we're looking for, especially the viruses, are able to migrate in the currents in a big way."

Those pollution points are mostly the dozens of rivers that crisscross metropolitan Rio and dump hundreds of millions of liters of raw sewage into the bay each day. By the government's own estimate, just half of the city's wastewater flowing into the bay is treated. [more]

    Do you have any articles on the environmental impact of golf courses? Pesticide use, water use, etc.

    The Olympics is not about competition, it's about money and that's why these Olympics will not be cancelled.

    All modern sports events are about money, so this isn't an exclusive crime, it's ubiquitous.

    Nobody cares.

    Gladiator sports for the masses while Rome burns. And still, nobody cares.
