Transcript for Brain-Eating Amoeba Found in Louisiana Water Supply
We want to move now to a health alert about dangerous water in one Louisiana community. A potentially deadly amoeba has been found in the water supply for thousands of people and ABC's Steve osunsami has the story. Reporter: This morning, a deadly brain-eating amoeba often found in warm ponds and Lakes is now tainting the drinking water of nearly 13,000 people in St. John the Baptist parish, Louisiana. The problem is making sure you keep precautions to keep it from going up your nose. Reporter: Health officials are warning residents to keep water from getting into their noses while swimming or bathing and telling parents to keep a close high with children playing with hoses or sprinklers. It finds itself way back in our noses and then can work its way into our central nervous system around our brains and once it's there it just causes destruction. Reporter: The amoeba breeds in warm standing bodies of water, even a pool that's poorly chlorinated. Infections are rare but almost always fatal. Today officials will begin a chlorine burn to clear the water but that will take them 60 days. We're taking every step necessary to relieve that threat. Reporter: Last month Haley Yust died from a brain-eating amoeba. She was a waterskiing. 130 reported cases and only 3 people sur vied. Kaley Harding was one of them hospitalized for nine weeks after contracting the disease in an Arkansas water park. I was real sick. Reporter: For "Good morning America," Steve osunsami, ABC news, Atlanta.
