“The adult patient reportedly performed nasal rinsing daily with unboiled tap water, which is thought to be the source of the infection,” it said in a statement. The unnamed man lived in the Charlotte County of Florida. The county refused to answer questions from the media, instead putting out a statement: “Our water system tests and adheres to all rules and regulations from the Florida Department of Environmental Protection and the EPA regarding safe drinking water. As for this incident, I refer you to the Florida Department of Health regarding any further information.” Primary amebic meningoencephalitis: a deadly infection Primary amebic meningoencephalitis or PAM is caused only if the pathogen enters through the nose and travels up to the brain along the olfactory nerve.
Drinking contaminated water does not lead to infection. Symptoms usually begin one to nine days after exposure and start with severe headaches, fever, nausea and vomiting. The infection progresses rapidly. In the second stage the infected person can experience hallucinations, stiff neck, seizures and can slip into a coma. There are no known effective treatments for PAM, although doctors use a combination of drugs thought to have some impact on Naegleria fowleri and to manage symptoms.
