Texas woman dies from brain-eating amoeba after using RV tap water for nasal rinse

In 2024, a 71-year-old woman in Texas tragically passed away after contracting Naegleria fowleri, a rare brain-eating amoeba. During her stay at a campground, she used tap water from a recreational vehicle (RV) to fill a nasal rinse device without boiling the water beforehand. Symptoms of primary amebic meningoencephalitis appeared days later, including fever and headaches, leading to her hospitalization. Despite attempts to treat her, she died eight days after her symptoms began. The Centers for Disease Control and Prevention (CDC) investigated the case, confirming the presence of the amoeba in her cerebrospinal fluid and emphasizing that her use of unboiled tap water was the likely cause of infection. The investigation revealed significant issues with the water quality from the RV and the campground's municipal supply. Tests showed that disinfectant levels were below state standards, and turbidity was high, suggesting a potential breakdown in disinfection. While no N. fowleri was detected in the water samples collected from the camp, investigators warned that harmful organisms could flourish in biofilms if water quality fails. These findings raised awareness about the critical importance of ensuring safe water for any nasal procedures. The CDC reiterated that although infections from Naegleria fowleri are infrequent in the United States, they usually prove fatal. Individuals are reminded to use only distilled, sterilized, or boiled water for nasal rinsing to prevent such dangerous infections. This unfortunate incident serves as a stark reminder about the serious health risks associated with improper use of nasal irrigation devices, particularly in relation to the quality of water used. Shocking statistics reveal that fewer than ten cases in the U.S. occur each year, yet the mortality rate is alarmingly high. Therefore, proper precautions must be taken to avoid a similarly tragic outcome for others. As millions of Americans enjoy outdoor activities, including swimming in freshwater lakes and using RVs, it becomes even more essential to follow recommended safety guidelines when it comes to water usage. Many people may not be aware of the dangers posed by unboiled tap water, but incidents like this reinforce the critical need for public awareness and consistent education regarding water safety and the risks associated with Naegleria fowleri. The CDC’s recommendations are clear: tap water should never be used for nasal rinsing unless treated properly to ensure it is free from harmful pathogens.
