Warm water seems to increase the likelihood of it's existence..BD
This thing is just there. It's lurking like some deadly thing in the water which can take our children's lives and we all have to be aware," said Orange County Health Department Director Dr. Kevin Sherin. The "thing" isn't a fish or alligator. It is so small it cannot be seen with the naked eye. The killer that lives in the hot, fresh water is a single cell amoeba that once exposed to the human brain through the nasal passages is almost always fatal.
At first people exposed to the amoeba, naegleria fowleri, suffer from flu-like symptoms. Very quickly, in from one to 14 days, the symptoms worsen, Sherin said. "There's a downhill course. Folks lapse into a coma; there are abnormal movements of the eyes and a terrible cascade of events leading to the actual death of parts of the brain." So, at 15 parks and lakes around the city, warnings about the amoeba have been posted. The signs urge bathers to wear nose clips or stay out of water warmer than 80 degrees Fahrenheit, which can be a breeding ground for the amoeba.
