When the heat is on and the beach is miles away, you may find yourself at the edge of a pool, ready to jump in all of its chlorinated glory. But before you take the plunge, be aware of what lies within the waters below. According to a recent survey conducted by the
Water Quality and Health Council, 17 percent of adults admit to urinating in a pool. Another 35 percent don’t shower before taking a dip and 63 percent are unaware of the health consequences that come with swimming in contaminated water.
Swimming pools that have not been cleaned properly have caused outbreaks of
E coli O157, several types of intestinal infections and unsanitary hot tubs/whirlpools have caused outbreaks of legionellosis [a bacterial disease which may cause pneumonia] and
"hot tub rash", according to Dr. Arthur Reingold, Professor and Head of the Division of Epidemiology in the School of Public Health at UC Berkeley.
But while these illnesses sound frightening, the way they’re transmitted is even more stomach turning. Many bacterial and parasitic infections are fecal-oral, which means they arise when fecal matter is orally ingested, which is disturbingly probable if you take a big gulp of pool water, according to Dr. Kathryn Jacobsen, assistant professor in the College of Health and Human Services’ Department of Global and Community Health at George Mason University. “The most common disease spread through pool water is diarrhea, and the people most likely to get sick are young children and people with weakened immune systems.” Luckily, Jacobsen stresses that “most public pools are very well monitored,” minimizing the chance of infection, despite several outbreaks reported each year.
