How warm is warm?
I jumped of a boat into a lake in east Tenn. a couple weeks ago. The water went up my nose and THEN I remembered our friend with boundary issues, N. fowleri.
So my kids should be fine because I told them to hold their noses.
The water was a real pretty greenish color. How warm is warm?
The early symptoms of Naegleria fowleri infection are similar to those caused by other more common illnesses, such as bacterial meningitis . People should seek medical care immediately whenever they develop a sudden onset of fever, headache, stiff neck, and vomiting, particularly if they have been in warm freshwater recently.
Naegleria fowleri is a heat-loving (thermophilic) organism. It grows best at higher temperatures up to 115°F (46°C)
