Risk factorsBy Mayo Clinic staff
In the United States, millions of people are exposed to the amoeba that causes naegleria infection each year, but fewer than 10 people a year get sick from it.
Some factors that might increase your risk of naegleria infection include:
- Freshwater swimming. Most people who become ill have been swimming in a freshwater lake within the past two weeks.
- Heat waves. The amoeba thrives in warm or hot water.
- Age. Children and young adults are the most likely age groups to be affected, possibly because they're likely to stay in the water longer and are more active in the water.
