FORT WAYNE, Ind. (WFFT) - A hard-to-kill intestinal parasite is showing up in swimming pools across the country.
The Centers for Disease Control and Prevention said Crypto cases are up more than 10% since 2009.
The parasite is most common in pools and causes diarrhea.
"When you think about it, yeah it is a concern," said Adina McGriff, who was at Northside pool with her son Thursday.
McGriff said she always tries to take precautions with her son.
"I always shower when I get home too, when I leave here. Because you never know," she said.
"Crypto" spreads through humans or animal waste, and can survive up to 10 days in chlorinated pool water.
Fort Wayne Parks and Recreation are always checking their levels.
"Too high of levels is also equally damaging as too low of a level. It's not safe if your if your chlorine, PH is too high," said Jenny Barney, Fort Wayne Parks aquatic director.
The best way to protect yourself is to follow rules posted at the pool including showering before and after getting in the water and staying out if you've recently had diarrhea.
"As long as you trust where you are going, then you won't too much worry about it at that point," said McGriff.
The Allen County Health Department said there have been 6 cases of Crypto reported, which is up slightly from this time last year.
