Recreational Water Illness Prevention Week
Overview
The week preceding Memorial Day has been designated as National Recreational Water Illness Prevention Week. This yearly observance is an opportunity for swimmers to learn more about recreational water illnesses (RWIs) and the steps they can take to protect themselves. Our goal is to highlight the importance of healthy swimming, healthy swimming behaviors, and recreational water illness prevention. This is done by emphasizing operation and prevention tips for pool operators and pool patrons to ensure a healthy swimming experience.
What are RWIs?
RWIs are illnesses that are spread by swallowing, breathing, or having contact with contaminated water from swimming pools, water parks, spas, interactive fountains, lakes, rivers, or oceans. Diarrhea is the most common RWI, and it is often caused by germs like Cryptosporidium ("Crypto"), Giardia, Norovirus, Shigella, and E. coli O157:H7. Other common RWIs include skin, ear, respiratory, eye, neurologic, and wound infections. Children, pregnant women, and people with weakened immune systems are most at risk for RWIs.
