A health warning is going out in San Joaquin County for a microscopic parasite that is sickening people who go swimming.
People who become infected can expect diarrhea and stomach cramps for up to a month.
San Joaquin County Health officials have confirmed 17 cases of Crypto since early July with another 41 showing symptoms.
Jeff Carruesco with the County Environmental Health Department says such outbreaks are becoming more frequent nationwide.
“A common way to get it is from inadvertently ingesting swimming pool water or lake water or recreational water that is infected with the parasite,” says Carruesco.
Carruesco says even pools with regular chlorine won’t kill the parasite and symptoms can begin 2 to 10 days after someone becomes infected.
He warns people who’ve had diarrhea in the past 14 days not to go swimming in recreational water.
