Louisiana health officials are warning residents not to use nonsterilized tap water in neti pots after the deaths of two people who exposed their brains to a deadly amoeba while flushing out their nasal passages.
The amoeba, Naegleria fowleri, can be found in lakes and ponds as well as in contaminated lukewarm tap water. The organism doesn't pose a threat when ingested, but if it becomes lodged in a person's nose it can end up in the brain and cause an infection.
The infection, lethal in 95% of cases, triggers an array of symptoms that resemble those of bacterial meningitis, including vomiting, headaches and sleepiness. As it progresses, it can cause changes in a person’s behavior and lead to confusion and hallucinations. It usually causes death within one to 12 days, according to the Centers for Disease Control and Prevention.
The Louisiana Department of Health and Hospitals issued its warning after a 51-year-old woman in DeSoto Parish died after rinsing her sinuses with a neti pot, a small vessel used to pour warm water into one nostril and out the other. Earlier this year, a 20-year-old man near New Orleans died after contracting the infection in the same way.
