Rare, Fatal Amoeba Infection: Your Questions Answered
How Can I Protect Myself Against Brain-Eating Amoebas?
It makes sense to avoid swimming underwater, diving, water skiing, and jumping in warm, still waters during the late summer. It also makes sense to wear a nose clip when swimming, boating, or playing in or on warm waters.
However, there's no scientific proof that these measures will prevent N. fowleri infection. Millions of people play in warm waters every summer without having their brains infested by amoebas.
It's a waste of time to put up signs warning that a body of water contains N. fowleri amoebas. There may be more or fewer amoebas depending on the time of year and other factors. More importantly, putting up such signs might imply that bodies of water without signs are safe -- and brain-eating amoebas are relatively common.
