TEXAS LAKE AND RIVER SWIMMERS REMINDED OF POTENTIAL HEALTH RISKS

When you pack safety items for a family trip to a Texas lake or river this season, you probably will bring sunscreen, insect repellant and floatation devices. But did you remember the nose plugs?

You may not know it, in fact few people do, but nose clips could help prevent a rare but deadly disease caused by a microorganism that can be found in untreated fresh water. With the weather really starting to heat up, the Brazos River Authority encourages visitors to have fun, while being aware of health risks associated with swimming in stagnant or slow-moving water.

Primary amebic meningoencephalitis (PAM), is a rare disease caused by naegleria fowleri, an amoeba found in almost all untreated, fresh surface water and in soil. The amoeba thrives in low levels of fresh water that is warmer than 80 degrees and stagnant or slowmoving.

The PAM infection occurs when water containing the organism is forced into the nasal passages – usually from diving or jumping into water or from water skiing. The amoeba makes its way into the brain and spinal cord, destroying brain tissue. Again, while the disease is extremely uncommon, identified cases thus far have almost always been lethal.

According to state health officials there have been only 10 cases of PAM diagnosed in Texas since 2000, including the death last year of an Arlington boy. In that case, 7-year-old Kyle Lewis died a few days after a swimming trip with his family. Since this tragedy, Kyle’s family have taken up the call to urge parents to be aware of the issue and to use protection such as nose clips when their children swim in fresh, untreated water.

There have been no known PAM cases in Texas yet this year. Symptoms of the infection include severe headache, high fever, stiff neck, nausea, vomiting, seizures and hallucinations as the condition worsens. Although PAM is rare, those infected usually succumb to the disease within a week.

To help reduce the already low chance of infection, state health officials recommend that those taking part in warm, fresh water-related activities use nose clips or hold their noses shut while jumping into water. With the amoeba often found in soil, it is best to avoid stirring up underwater sediment. Health officials recommend people avoid stagnant or polluted water and take “No Swimming” signs seriously.

PAM cannot be spread person to person nor by drinking water. Swimming pools and hot tubs that are properly cleaned, maintained and chlorinated are generally safe, as is salt water.
