PALATKA, Fla. -- The Florida Department of Health says there are tiny parasites found in freshwater areas, such as lakes and ponds -- and they could be deadly.
The parasite is a dangerous amoeba called Naegleria.
The amoeba can get into your body through your nose, and then make their way to the brain.
Once in the brain, it creates an infection called amoebic meningoencephalitis, or PAM for short. It's usually fatal within five days.
Symptoms include confusion, lack of attention, loss of balance, seizure and hallucinations.
Health experts said the amoeba grows in the muck on the bottom of lakes or ponds, so they recommend not stirring up the bottom.
Experts also recommend people keep their head out of the water or hold their nose.
Swimmers at Lake Broward in Pomona Park put on plenty of sunscreen to protect against the sun but didn't know about the deadly amoeba.
"I normally plug my nose all the time because I can't stand the water in my nose," said swimmer Keely Wheeler.
Wheeler's home county of Putnam along with Baker County have seen fatal cases of the disease in the last few years.
But Shannon Thomas said swimming in lakes always carries risks.
"Snakes, gators! There's no telling," Thomas said.
She said she won't change her ways even after hearing about the amoeba.
