In recent years, the popularity of nasal irrigation, particularly through devices like neti pots, has surged as a natural remedy for sinus congestion and allergies. However, a recent report from the Centers for Disease Control and Prevention (CDC) has shed light on a concerning association between nasal irrigation and Acanthamoeba infections—and the issue lies in the fact that many individuals fail to use sterilized water for their nasal irrigation. Learn more about the report and the potential risks below.
Nasal irrigation linked to amoeba infection
Nasal irrigation involves rinsing the nasal passages with a saline solution to flush out mucus and debris. Neti pots, resembling small teapots, are commonly used for this purpose. Users fill the pot with a saline solution and pour it through one nostril, allowing it to flow out through the other, effectively clearing the sinuses.
According to the CDC's report, ten individuals who contracted Acanthamoeba infections had practiced nasal irrigation before falling ill. Three of these patients died of their infections.
Acanthamoeba is a genus of amoebae known to cause two severe infections: Acanthamoeba keratitis, affecting the eyes, and Granulomatous Encephalitis, which attacks the brain and spinal cord. Acanthamoeba keratitis manifests as a painful eye infection, while Granulomatous Encephalitis infiltrates the central nervous system, resulting in symptoms ranging from headaches and nausea to seizures and hallucinations. Granulomatous Encephalitis is often fatal.
This isn't the first time neti pots have been associated with amoebic infections. Previously, concerns were raised about Naegleria fowleri, also known as the brain-eating amoeba, which can thrive in tap water. Instances of individuals using tap water in their neti pots inadvertently introduced the amoeba into their nasal passages, leading to severe infections.
To mitigate the risk of Acanthamoeba infections, health experts emphasize the importance of using distilled or sterilized water in nasal irrigation practices. Tap water should be boiled and cooled before use to eliminate any potential contaminants. The report stresses that educating individuals, particularly those with compromised immune systems, about the dangers of using unboiled tap water for nasal rinsing could significantly reduce the incidence of invasive Acanthamoeba infections.
Bottom line
While nasal irrigation can offer relief from sinus symptoms, the recent CDC report underscores the need for caution. By adopting preventive measures and promoting awareness, individuals can protect themselves from potentially fatal infections.
