This month, the rare infection killed a 16-year-old Florida girl, who fell ill after swimming, and a 9-year-old Virginia boy, who died a week after he went to a fishing day camp. The boy had been dunked the first day of camp, his mother told the Richmond Times-Dispatch.
Those cases are consistent with past cases, which are usually kids — often boys — who get exposed to the bug while swimming or doing water sports in warm ponds or lakes.
The third case, in Louisiana, was more unusual. It was a young man whose death in June was traced to the tap water he used in a device called a neti pot. It's a small teapot-shaped container used to rinse out the nose and sinuses with salt water to relieve allergies, colds and sinus trouble.
Health officials later found the amoeba in the home's water system. The problem was confined to the house; it wasn't found in city water samples, said Dr. Raoult Ratard, Louisiana's state epidemiologist.
