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.

Isn't precaution number one when using neti pots to never do it with plain tap water?

[–] prettybunnys@sh.itjust.works 14 points 1 day ago

Yes, but precaution number one when driving or riding in a motor vehicle is putting on your seatbelt and tons of folks dgaf about that either

For as much as I despise the pool water that comes out of my tap I can at least feel safe using my neti pot.

So not just tap water but her RVs tap water. The attempt at scare-mongering - tap water - like it could happen to anyone is annoying.

[–] andros_rex@lemmy.world 89 points 2 days ago (2 children)

You can’t use tap water straight for Neti pots. I’m pretty sure every single neti pot tells you to boil the water first.

[–] Widdershins@lemmy.world 46 points 2 days ago (13 children)

I hope it tells you to let the boiling water cool, too. I feel like that's an important step.

[–] dream_weasel@sh.itjust.works 12 points 1 day ago (3 children)

It doesn't clean the sinuses as well. I personally run the boiled water through my soda stream, then directly into the face holes.

What's the difference between a neti pot and taking a shower? I'm pretty sure I get water up my nasal cavity every time I shower. Is the neti pot warning a cya thing or is there a greater risk?

[–] Taleya@aussie.zone 16 points 1 day ago

Big difference between a little water in your schnozz and a deep irrigation of your sinus cavities.

Use (cold) boiled or distilled water

[–] Nindelofocho@lemmy.world 3 points 1 day ago (4 children)

Its the same amoeba you can get swimming in lakes. It doesn’t happen every time but it CAN happen. It is grossly ignorant to not be cautious of it

[–] Duamerthrax@lemmy.world 1 points 1 day ago (1 children)

Is it more likely to come from reservoirs then it is from wells that tap the water table?

It could, with warming temperatures the bacteria is moving north. Showing up in areas unfamiliar with it

But you’re way more likely to get it by swimming and just don’t pour water up your nose

Well, they're not sure if the water came directly from the RV tank or the local water supply, so it certainly could have been tap water.

The potable water tank, the investigation found, was filled before the woman bought the RV three months ago and could have contained contaminated water. The investigation also concluded that the municipal water system, which was connected to the potable water system and bypassed the tank, could have caused the contamination.

The agency stressed the importance of using distilled, sterilized or boiled and cooled tap water when people perform nasal irrigation to reduce the risk of infection and illness.

Sounds like the general idea is also just don't use tap water directly out of the tap if you want to run water through your sinuses (which is where these infections come from). They aren't saying that tap water is unsafe to drink. I don't see this as fear mongering at all.

I'll just keep chilling out safely over here on Team Blow Your Nose With A Tissue.

[–] ILikeBoobies@lemmy.ca 6 points 1 day ago

You can use steam to break up mucus, making it easier to use a tissue

[–] ColeSloth@discuss.tchncs.de 48 points 2 days ago (4 children)

This wasn't the tap waters fault. This was the rv water tanks fault, most likely. Most people pretty much never clean\sanatize them.

[–] Nindelofocho@lemmy.world 3 points 1 day ago (3 children)

Neti pot instructions typically state you need to use distilled or boiled water. You should follow these instructions regardless of the quality of your municipal water. It does not hurt to do so

[–] milicent_bystandr@lemm.ee 3 points 1 day ago (1 children)

It does not hurt to do so

Unless, like another commenter, you panic and forget to let the boiled water cool enough!

[–] Nindelofocho@lemmy.world 3 points 1 day ago (1 children)

Pro tip, boil water and put it in the freezer for later! /s

[–] milicent_bystandr@lemm.ee 2 points 1 day ago (1 children)

Squirt ice up your nose!

But for real, boiling water and keeping it in a container for later is a common strategy in many places.

Those icicles reach places even a pinky can't hit

Apparently this is why you can’t actually go in the Roman Baths in Bath.

Just pick your nose like a normal person. Sheesh.

[–] CidVicious@sh.itjust.works 107 points 2 days ago (18 children)

Neti pots and similar have very, very clear warnings that the water needs to be sterilized.

I'm getting convinced kennedy's worm caused this.

[–] xeekei@lemmy.zip 4 points 1 day ago (7 children)

Can this happen in Sweden as well? 'Cos I clean mine with shower water almost every shower.

[–] Quexotic@infosec.pub 6 points 1 day ago (2 children)

Use distilled ONLY. With good chlorinated city water systems it's still very unlikely to happen, but it's such a horrible way to go, just get some distilled from the store.

I believe the amoeba grows in warm water, which is why hot springs in New Zealand are at risk. So hopefully you're more safe! You might want to check better info than me though!
