The New York Times (7/12, D7, Brody) reports that people swimming in pools, lakes, or rivers need to be mindful of “what the Centers for Disease Control and Prevention calls a ‘recreational water illness,’ an infection or irritation caused by germs or chemicals contaminating the water” that may “cause ailments of the ears, eyes, skin, nervous system, gastrointestinal and respiratory tracts, and” infect any cuts or scratches.
