In a follow-up report, for the second time this summer, a person has contracted the brain-eating amoeba, Naegleria fowleri.

Jacksonville media report that 13-year-old Tanner Wall of Palatka had contracted the lethal parasite this summer in July and died on Aug. 2. It is believed this occurred while on vacation at a North Florida campground.

This followed a case reported about a month prior in Hillsborough County. The identification of the first patient or the condition has not been disclosed.

Naegleria fowleri is a microscopic amoeba which is a single-celled living organism. It can cause a rare and devastating infection of the brain called primary amebic meningoencephalitis (PAM). 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 (which destroys brain tissue) and is usually fatal. Infections usually occur when it is hot for prolonged periods of time, which results in higher water temperatures and lower water levels.

Naegleria fowleri infections are rare. Most  infections occur from exposure to contaminated recreational water. Cases due to the use of neti pots and the practice of ablution have been documented.

You cannot be infected with Naegleria fowleri by drinking contaminated water and the amoeba is not found in salt water.

Initial symptoms of PAM usually start within 1 to 7 days after infection. The initial symptoms may include headache, fever, nausea, or vomiting. Other symptoms can include stiff neck, confusion, loss of balance, seizures, and hallucinations. After the start of symptoms, the disease progresses rapidly.
