How can I reduce the risk of infection with Naegleria fowleri?
It is likely that a low risk of Naegleria fowleri infection will always exist with recreational use of warm freshwater lakes, rivers and hot springs. The low number of infections makes it difficult to know why some people have been infected compared to the millions of other people using the same or similar waters across the U.S. The only way to prevent Naegleria fowleri infections is to refrain from water-related activities. If you do plan to take part in water-related activities, here are some measures that might reduce risk: • Avoid water-related activities in bodies of warm freshwater during periods of high water temperature and low water levels • Hold the nose shut or use nose clips when taking part in water-related activities in bodies of warm freshwater such as lakes, rivers, or hot springs. • Avoid digging in or stirring up the sediment while taking part in water-related activities in shallow, warm freshwater areas.
