Swimming is a popular, fun summer activity with health benefits for people of all ages. It is important to remember, however, that pools and other types of recreational water venues can be places where germs can spread.
Recreational Water Illnesses (RWIs) are caused by germs spread by swallowing, breathing in mists or aerosols of, or having contact with contaminated water in swimming pools, hot tubs, water parks, water play areas, interactive fountains, lakes, rivers or oceans1. RWIs can include infections of the skin, eye, ear, respiratory, neurologic and gastrointestinal system. The most common symptom of RWI is diarrhea, which can be caused by germs such as Crypto (short for Cryptosporidium) Giardia, Shigella, norovirus and E. coli . Other infections include Legionella, Hot Tub Rash, Swimmers Ear and MRSA.
Swimmers and individuals playing in interactive fountains and spray parks share the water with everyone. People with diarrheal illness who swim can quickly contaminate the water with millions of germs. Even water that is properly chlorinated can be potentially harmful as it can take anywhere from a few minutes to several days to remove some types of illness-causing organisms from the water. Swallowing even a small amount of recreational water that has been contaminated with germ-containing feces.
Fortunately there are steps that everyone can take to help keep recreational water safe.
