Four days later, she developed a fever, headache and confusion.Doctors suspected PAM and began treatment, but her condition got worse. She had seizures and died eight days after symptoms began, CBS News said."Improperly maintained municipal water and recreational vehicle (RV) water systems can be a source of waterborne disease. CDC recommends the use of distilled, sterile, or boiled and cooled tap water for nasal irrigation," the report said.The amoeba enters the body through the nose and travels to the brain.
