Awareness of illnesses and healthy swimming behaviors play an important role in stopping the spread of illnesses through recreational water, according to the Minnesota Department of Health (MDH).
"Germs on and in swimmers' bodies end up in the water and can make other people sick," said Dr. Kirk Smith, foodborne disease supervisor for MDH "Even healthy swimmers can get sick from recreational water illnesses, but the young, elderly, pregnant women and people with weakened immune systems are especially at risk."
Specific actions you can take to promote healthy swimming include:
- ?If you have been ill with diarrhea in the past two weeks, do not go swimming.
- ?Do not allow children who have been ill with diarrhea or vomiting in the past two weeks to go swimming.
- ?Avoid swallowing water or getting water in your mouth.
- ?Shower before swimming.
- ?Wash your hands after using the toilet or changing diapers.
- ?Take children on bathroom breaks or change diapers often.
- ?Change children's diapers in a bathroom, not at poolside or beachside.
From 2000 to 2007, 17 swimming pool outbreaks and 12 beach outbreaks were identified in Minnesota.
The parasite cryptosporidium, one of the most common waterborne disease agents, is a chlorine-resistant parasite that can survive and be transmitted even in a properly maintained pool. In 2007, a record number of 302 cases of cryptosporidium were reported to MDH. Three swimming pool outbreaks of cryptosporidiosis occurred in 2007.
