Where are RWIs found? 

Monday, March 09, 2009 2:14:59 PM
RWIs can be spread through use of swimming pools, hot tubs, decorative water fountains, oceans, lakes and rivers.

Swimming Pools, Waterparks, Spray Features

The most common illness spread through use of swimming pools is diarrhea. If swimmers are ill with diarrhea, the germs that they carry can contaminate the water if they have an "accident" in the pool. On average, people have about 0.14 grams of feces on their bottoms which, when rinsed off, can contaminate recreational water. When people are ill with diarrhea, their stool can contain millions of germs. Therefore, swimming when ill with diarrhea can easily contaminate large pools or waterparks. As a result, if someone swallows water that has been contaminated with feces, he/she may become sick. Many of these diarrhea-causing germs do not have to be swallowed in large amounts to cause illness. Remember that standing water is not necessary for RWIs to spread so even spray decks can become contaminated (the water is just in a collection tank underground) and spread illness. To ensure that most germs are killed, chlorine or other disinfectant levels and pH should be checked regularly as part of good pool operation.

The most commonly reported RWI is diarrhea. Diarrheal illnesses can be caused by germs such as Crypto, short for Cryptosporidium, Giardia, Shigella, norovirus and E. coli O157:H7.
