Are Certain Groups Affected More Than Others?
Over 60% of U.S. cases are in children age 13 or younger. About 80% of cases are in males.
It's not at all clear whether children or males are more susceptible to the amoeba, or whether young males are more likely to engage in activities that expose them to the amoeba.
How Can I Protect Myself Against Brain-Eating Amoeba?
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.
It's also a good idea to avoid stirring up mud while taking part in such activities.
And if you are cleansing your nostrils, be sure to fill your neti pot or squeeze bottle with distilled or sterile water and not tap water. You can also use water that has been boiled for one minute (three minutes at high elevations) and then cooled. And you can filter the water using filters with pores no larger than 1 micron (1 micrometer).
