Several local municipalities and private pools have recently been closed due to possible or confirmed outbreaks of the infectious parasite that causes cryptosporidiosis.

“Crypto,” as it is commonly called, is highly contagious and causes diarrhea.

Water is the most common method of transmission, and, unfortunately, the parasite that causes the disease is “very resistant” to chlorine disinfection, according to the federal Centers for Disease Control and Prevention (CDC). Cryptosporidiosis outbreaks are common and can occur both from recreational water (splash zones, water parks, splash and spray pads, etc.) and from drinking water.

• Wash your hands thoroughly and often with soap and water, especially after changing diapers or using the toilet.
• Don’t swim or play in recreational water if you have cryptosporidiosis for at least two weeks after your symptoms have stopped. Cryptosporidiosis can remain on the skin for long periods and can be washed off and infect other people.
• Don't let your child swallow recreational water.
• Avoid close contact with anyone with a weakened immune system. They are most at risk of more serious adverse effects from the disease.
• Keep your child with diarrhea home and away from child care settings until his or her diarrhea has stopped completely.
