CDC warns about potentially risky fecal parasite lurking in swimming pools


"In a recently released survey, about 24 percent of people would jump in an hour after diarrhea so that would be something that would advise against", said Dr. Rodgers.

The Center for Disease Control is advising those that will be swimming in a pool this summer to make sure and shower off after swimming.

The concern with crypto, according to the CDC, is that it's tough to kill.

Most people who get crypto get it from the pool, but you can also get it from lakes and cattle.

A troubling survey from the Water Quality and Health last month found that "half of Americans use swimming pools as communal bathtubs". The Giardia parasite will survive for about 45 minutes, and Cryptosporidium's 10.6-day lifespan translates to about 15,300 minutes.

Youngsters sick with diarrhea should not be placed in child care, according to the CDC, and following a cryptosporidiosis outbreak, child care workers should clean surfaces with hydrogen peroxide, as chlorine bleach is an ineffective means of killing the parasite.

The most common cause of the outbreaks was swallowing contaminated water from recreational places, researchers said.

Crypto, a parasite, is spread through the poop of infected humans or animals.

As for pools, anyone suffering diarrhea should avoid swimming until at least two weeks after their diarrhea subsides, the CDC says.

The CDC said that over the past decade, there have been more than 400 reported outbreaks in the United States, leading to almost 7,500 people becoming sick. It causes cryptosporidiosis, which can leave healthy adults suffering from "profuse, watery diarrhea" for as long as three weeks.

"The annual number of reported cryptosporidiosis outbreaks overall increased an average of approximately 13% per year over time". The cases tend to rise from June to August, according to the CDC. Others swimming in the contaminated water can get the parasite when they ingest the water.

"We watch the reports from the news to find out what beaches are closed and what beaches may be having problems", said Kearsley resident Wayne Smith". Dr Rodgers said if you have any of the symptoms, to stay out of the water.

Test strips could be purchased from hardware stores to look for adequate chlorine or bromine levels as well as correct pH of the water.
