A lone sunbather relaxes near a warning sign reading "Inappropriate for bathing" along the Leblon beachfront in Rio de Janeiro May 19. Rio had no sooner patched up its main sewage line, which had dumped tons of raw sewer into the sea, and lifted a month-long swimming ban last week when leaks sprang in other parts of the aging system, spewing out a fresh wave of contamination along the shoreline. The city was forced to reimpose no-swim zones on the main tourist beaches such as Leblon, which runs as an extension to Ipanema, one of Rio's most famous. The high level of pollutants in the surf have a risk for causing hepatitis, typhoid fever or intestinal parasites, environment officials said.
