The woman contracted a fatal infection caused by a brain-eating amoeba and died eight days after developing symptoms.

A Texas woman died from an infection caused by a brain-eating amoeba days after she cleaned her sinuses using tap water, according to a Centers for Disease Control and Prevention case report.

The woman, an otherwise healthy 71-year-old, developed "severe neurologic symptoms," including fever, headache and an altered mental status, four days after she filled a nasal irrigation device with tap water from her RV's water system at a Texas campsite, the CDC report said.

She was treated for primary amebic meningoencephalitis — a brain infection caused by Naegleria fowleri, often referred to as the "brain-eating amoeba." Despite treatment, the woman experienced seizures and died from the infection eight days after she developed symptoms, the agency said.

I'm seeing many, many comments from people who have never used a neti pot or have questions. There are some basic answers, from a man who has, at times, safely used a neti pot.

You only use a neti pot with distilled water or previously boiled water. I use water fresh off a boil, cooled down just enough to where my nose can tolerate it. You can use that expensive gentle salt or table salt or sea salt, anything is fine.

You guys have no idea how satisfying it is when your head is all stuffed up with snot, blowing with a tissue is impossible....and you cycle some warm saline solution in your sinuses & a massive glob of 3-4 tablespoons of snot effortlessly glides out your other nostril into the sink & you can breathe again. It is a disgusting miracle when you're sick, it is amazing.

Let's clarify a few things -- always use distilled or previously boiled water, as the brain-eating amoeba is present in most of North America's waters. It can potentially survive water processing plants, and possibly domestic hot water tanks. The brain-eating amoeba can only survive in warm, moist environments....like your sinuses right next to your brain....it must be forcibly injected into there, so no cannonballs into the lake. No snorting untreated lake water. Normal swimming is okay.

You can use the neti pot too much. I was using it to aggressively clear out my sinuses for a year with limited success, and it turns out I am allergic to a mold or fungus at my workplace. Very frequent use of the neti pot only irritated my nose further, causing it to become inflamed (but not dangerous), and it would never ever cure the root problem: allergies. That was only fixed by pills & anti-histamine spray.

There is no need to be afraid of the neti pot, or the brain-eating amoeba, so long as you use the neti pot responsibly. Correctly.

I use saline I buy at the drug store for something like $1 a liter. No brain amoebas for me!
