There will be lots of bad stuff floating in the nation’s swimming pools this summer.
CNN tells us that outbreaks of parasitic diarrhea-causing infection linked to pools and water playgrounds doubled in the United States from 2014 to 2016.
The key germ that causes illness is cryptosporidium, which can make people sick for up to three weeks. It spreads through contact with the feces of an infected person.
In a single bowel movement, millions of cryptosporidium parasites can be released from an infected human or animal, according to the CDC.
Crypto may be found in water sources, including private wells, that have been contaminated with feces from infected humans or animals. Sewage overflows, polluted stormwater and agricultural runoff may also contaminate water.
The single most important thing one can do to prevent the illness is to avoid drinking any pool water.
