Brain-Eating Amoeba Infection Claims Life of Texas Woman

Introduction to the Incident

A Texas woman died from an infection caused by a brain-eating amoeba days after cleaning her sinuses using tap water, according to a Centers for Disease Control and Prevention (CDC) 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.

Symptoms and Diagnosis

The woman was treated for primary amebic meningoencephalitis (PAM) — a brain infection caused by Naegleria fowleri, often referred to as the "brain-eating amoeba," the CDC said. Despite treatment, the woman experienced seizures and died from the infection eight days after she developed symptoms, the agency said. Lab tests confirmed the amoeba in the woman’s cerebrospinal fluid, according to the report.

Cause of Infection

The CDC said the infection usually occurs after "recreational water activities" but noted that cleaning sinuses with non-distilled water is also a risk factor for developing PAM. An investigation conducted by the agency found that the woman had not recently been exposed to fresh water but had done the nasal irrigation using non-boiled water from the RV’s potable water faucet "on several occasions" before her illness.

Investigation Findings

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.

Prevention of Infection

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

Conclusion

The case highlights the importance of taking precautions when using tap water for nasal irrigation. Using distilled or sterilized water can significantly reduce the risk of contracting PAM. It is crucial for individuals to be aware of the risks associated with using non-sterilized water for sinus cleaning and to take necessary precautions to prevent such infections.

FAQs

• Q: What is primary amebic meningoencephalitis (PAM)?
  A: PAM is a brain infection caused by Naegleria fowleri, often referred to as the "brain-eating amoeba."
• Q: How is PAM typically contracted?
  A: PAM is usually contracted through recreational water activities or by cleaning sinuses with non-distilled water.
• Q: Can PAM be prevented?
  A: Yes, PAM can be prevented by using distilled, sterilized, or boiled and cooled tap water for nasal irrigation.
• Q: What are the symptoms of PAM?
  A: Symptoms of PAM include fever, headache, and altered mental status, and can progress to seizures and death if left untreated.
• Q: How can I protect myself from PAM?
  A: You can protect yourself by using safe water for nasal irrigation, avoiding swimming in freshwater bodies with low water levels or warm water, and avoiding putting your head under water when bathing in freshwater lakes, rivers, and hot springs.
