71-year-old contracted deadly Naegleria fowleri infection while staying in RV campground
A 71-year-old woman has died from a rare and nearly always fatal brain infection caused by Naegleria fowleri, a microscopic amoeba commonly known as the “brain-eating amoeba.” According to a new report from the U.S. Centers for Disease Control and Prevention (CDC), the woman contracted the infection after using tap water from a recreational vehicle (RV) to rinse her sinuses at a Texas campground.
The incident was documented in the CDC’s Morbidity and Mortality Weekly Report (MMWR) last week, drawing attention to the hidden dangers of improper nasal irrigation and poor water sanitation in portable systems.
Fatal infection developed within days
The woman began experiencing neurological symptoms just four days after using the tainted water, initially presenting with fever, headaches, and confusion. Doctors at a local hospital quickly suspected primary amebic meningoencephalitis (PAM), a rare but severe brain infection caused by Naegleria fowleri.
Despite rapid medical intervention, the woman’s condition deteriorated quickly. She died just eight days after the onset of symptoms.
An amoeba was suspected in the RV water tank
Following her death, health officials from the Texas Department of State Health Services and the CDC launched an investigation into the source of the infection. The woman had been staying in an RV that used water from a portable tank connected to a municipal system during her trip. That tap water was used in a nasal irrigation device to clear her sinuses, a common practice that, when done improperly, can carry significant health risks.
Although no traces of the amoeba were detected in samples taken from the RV’s water system or the municipal source, officials noted the water had been tested 23 days after it was used, potentially too late to detect the organism. The RV’s water system was also found to be inadequately disinfected, creating conditions where N. fowleri could have thrived.
Warnings against using unsterilized water for nasal rinsing
“This case reinforces the potential for serious health risks associated with improper use of nasal irrigation devices, as well as the importance of maintaining RV water quality and ensuring that municipal water systems adhere to regulatory standards,” the CDC stated in its report.
Health officials strongly advise against using untreated tap water for nasal irrigation. Instead, they recommend using distilled, sterile, or previously boiled water to prevent infection.
What is Naegleria fowleri?
Naegleria fowleri was first discovered in the 1960s. Since then, only about 150 cases have been reported in the United States, but nearly all have been fatal. The amoeba is typically found in warm freshwater environments like lakes and hot springs, and infections usually occur when contaminated water enters the body through the nose.
While rare, the infection is often fast-moving and devastating, as seen in this case. The woman’s tragic death highlights the critical importance of proper hygiene and water sanitation practices, particularly when using nasal irrigation devices.
