Beware of brain-eating amoeba present in local waters
Scientists are warning the public of a brain-eating amoeba present in our local waters.
According to Dr. Paula Rivadeneira , adjunct professor of the University of Arizona Cooperative Extension, Naegleria fowleri is a single-celled living organism that can act as a parasite in animals and humans. Naegleria is commonly found in warm freshwater such ask lakes, rivers, and hot springs and soil.
Dr. Rivadeneira said this amoeba is present in local waters such as in the Colorado River and Lake Martinez, though it is highly unlikely someone would contract it.
Naegleria fowleri is found around the world. In the United States, the majority of infections have been caused by Naegleria fowleri from freshwater located in southern-tier states. The amoeba is most commonly found in warm bodies of water such as ponds, lakes, rivers, hot springs, and coastal waters and can survive temperatures of up to 45°C .
Naegleria fowleri infects people by entering the body through the nose. This typically occurs during recreational activities such as swimming, diving, jet skiing, water skiing, and wakeboarding in natural waters. It is not transferred from person to person.
Infection with Naegleria fowleri occurrence is rare, with only 400 cases documented worldwide. From 2000 to 2009, 30 infections were reported in the U.S. and at least six of these infections occurred in Arizona.
You cannot get a Naegleria fowleri infection from a properly chlorinated, cleaned, and regularly maintained swimming pool.
If you do plan to take part in water-related activities some measures that might reduce risk include:
â–ª Hold nose shut or wear nose plugs when jumping or diving into natural waters such as lakes, rivers, or hot springs.
â–ª Avoid swimming or diving in warm natural water during periods of high temperatures and low water volume.
â–ª Avoid digging in or stirring up sediment in shallow natural waters.
