The Florida Department of Health (DOH-Charlotte) has recently confirmed a Florida case infected with Naegleria fowleri, likely caused by practices involving tap water use for sinus rinsing.Naegleria fowleri is a microscopic single-celled amoeba found in warm lakes, rivers and soil that can cause infection to the brain called primary amebic meningoencephalitis (PAM).Drinking contaminated water does not put you at risk; however, health officials urge residents to take caution when using tap water for sinus rinsing: boil compromised water for at least one minute before using.More potential risks include unsupervised sprinklers or squirt guns being used by children; as such, small hard plastic/blow-up pools should be emptied and scrubbed after each use, and all swimming pools should be sufficiently sanitized. Anyone who experiences symptoms like headaches, fever or nausea – especially after swimming in warm inland bodies of water or after nasal exposure – are advised to seek medical attention immediately.
