A Tehama County child has contracted a serious and extremely rare infection after swimming in a lake. The child, less than 10-years-old, has been diagnosed with Primary Amebic Meningoencephilitis, which is so rare there have only been 10 known cases in California since 1971. It occurs when someone swims in water containing the Amoeba Naegleria Fowleri and water goes up the nose forcefully. It can then migrate to the brain and destroy brain tissue. That’s the only way the infection occurs, not by swallowing the water. Symptoms including severe headache, fever, nausea or vomiting. Tehama County Public Health has not said what the body of water was where the child picked up the infection.
