Brain-Eating Amoeba

As we wind down our summer activities, I recall seeing several cases in the news of people thacquiring serious infections from swimming in contaminated lakes and improperly treated pools. These events remind me of the lethal dangers of recreational water illnesses (RWIs).

The Centers for Disease Control and Prevention (CDC) estimate that one in eight public swimming pools are unsafe because of improper chlorination procedures.

Serious illnesses can result and these include gastrointestinal, skin, ear, respiratory, eye and even neurological infections. The most common symptom of such contamination is diarrhea, but any of these symptoms can turn lethal if not properly treated.

Of all the infections that one can get from summer activities, there is one in particular thatamoeba is as lethal as any I’ve come across. The disease is called primary amoebic meningoencephalitis, or PAM for short. Fortunately, PAM is rare and only 128 cases have been reported in the United States between 1962 and 2012.

The bad news is that of those 128 cases, there was only one survivor. PAM is a devastating infection of the brain caused by the free-living Naegleria fowleri organism. It’s been called the “brain-eating amoeba” in the media because the organism enters the body through the nose and travels up the olfactory nerve to the brain. It then causes the often-fatal PAM.

The Naegleria fowleri amoeba is found in warm freshwater (such as lakes, streams and hot springs) and the infection occurs when people go swimming or diving in MH900430603these waters. PAM can occur also from inadequately chlorinated swimming pools. Infections could even result from contaminated tap water if an individual uses the water to flush out the nose, as in using a neti pot for sinus irrigation.

Most infections occur in southern-tier states, with more than half of the occurrences in Texas and Florida, but cases have been identified in Louisiana after the hurricane Katrina hit the area. Aside from such a natural disaster, the PAM infection disproportionately affects males and children, probably as a result of their more aggressive water sports activities.

The infection presents much like bacterial meningitis. Symptoms include severe headache, fever, vomiting, neck stiffness and seizures. The most important medical clue leading to a proper diagnosis of PAM, however, is if the patient presents with the above-mentioned symptoms AND, in the two weeks prior to symptom onset, the patient swam in a freshwater lake, river or stream.

The only certain way to prevent this amoebic infection is to refrain fromMH900442342 swimming in warm freshwater. Barring that, there are several preventive measures one can take to reduce the risk of contracting this disease. You could hold your nose shut while diving into freshwater or use nose clips when swimming in these waters. The best safety measure is to keep your head above water at all times when enjoying outdoor water sports. And never put your head under water when soaking in natural hot spring pools.

Additional advice is to resist digging into or stirring up the sediment in shallow freshwater. The sediment is a perfect breeding ground for such amoeba. And when irrigating the sinuses with tap water, be sure to boil the water first for at least one minute (or for three minutes at elevations higher than 6,500 feet). And always allow the water to cool before use.

These measures may seem drastic, but a PAM infection is nearly ALWAYS FATAL, so act cautiously to ensure your safety against this lethal organism.

Thoughts? Comments? I’d love to hear them!
