Hillsborough County, Fla.— The Florida Department of Health (DOH) (click here) has confirmed one Florida case infected with Naegleria fowleri in Hillsborough County. Naegleria fowleri is a microscopic single-celled living amoeba. The amoeba can cause a rare infection of the brain called primary amebic meningoencephalitis (PAM) that destroys brain tissue and is usually fatal. The amoeba is commonly found in warm freshwater such as lakes, rivers, ponds and canals.

Infections can happen when contaminated water enters the body through the nose. Once the amoeba enters the nose, it travels to the brain where it causes PAM. Infections usually occur when temperatures increase for prolonged periods of time, which results in higher water temperatures and lower water levels. The peak season for this amoeba is July, August and September. Naegleria fowleri is found in many warm freshwater lakes, ponds and rivers in the United States, but is more common in southern states. The low number of infections makes it difficult to know why a few people have been infected compared to the millions of other people that used the same or similar waters across the U.S....
