FRESNO COUNTY, Calif. - With this heat, many folks in the Central Valley are starting to the hit the pool to cool off. But the Centers for Disease Control and Prevention warns, there is an outbreak of a parasite linked to swimming pools and water parks - and it's making people very sick.
Mark Maxwell brought his three-year old granddaughter to the Martin C. Reilly Park, despite the CDC's recent warning there is a parasitic infection on the rise in U.S. pools and water parks. It's called crypto, and the CDC there were twice as many reported cases in the U.S. in 2016 from 2014.
Fresno County environmental health specialist Stephanie Kahl said, "If someone is infected with crypto and they have diarrhea, they could potentially spread that to other people."
Kahl said parents should not bring their child around a public pool if they are sick, and they should teach their children not to swallow pool water. The CDC reports crypto is not easily killed by chlorine and can live up to ten days in properly treated water.
But Kahl said Fresno County public pools are highly monitored.
"We test the water quality and make sure that the sanitation levels are acceptable that the filtration is working," said Kahl.
Kahl said if you get infected with crypto, you can suffer watery diarrhea, stomach cramps, nausea, or vomiting.
Maxwell said it's good to be cautious, but he's not going to let crypto stop the fun this summer.
"I know it sounds kinda gross, but let kids be kids," ended Maxwell.
The CDC said those with healthy immune systems will typically pass the crypto without any treatment.
