Officials said that an Ohio teenager died earlier this week after visiting the U.S. National Whitewater Center near Charlotte.
"The U.S. National Whitewater Center, after discussion with the Centers for Disease Control (CDC) and local health officials, has decided to temporarily suspend all whitewater activities effective immediately," the Center said in a statement Friday.
"This decision was made by the Whitewater Center after initial test results found Naegleria fowleri DNA was present in the whitewater system," it added. "Only whitewater activities are suspended."
It is still not known why the amoeba, called Naegleria fowleri, occasionally kills people. It's often found in warm bodies of water such as lakes or ponds, but cases of infection are not so common. The amoeba is linked to the use of sinus-rinsing neti pots.
