The Centers for Disease Control and Prevention in Atlanta has confirmed a rare case of parasitic meningitis has been found in Arkansas.
The CDC says Arkansas had five cases of the waterborne illness between 1962 and 2012.
Parasitic meningitis is formally known as primary amebic meningoencephalitis. The CDC says the condition is typically fatal and that the infection occurs when people dive in warm freshwater places such as lakes and rivers. It typically enters a body through the nose and then reaches the brain.
It is usually fatal.
The Arkansas Department of Health has not said where the rare case of parasitic meningitis was found.
