Final answer:
Naegleria fowleri is a concern for public health because it causes a fatal brain infection called primary amoebic meningoencephalitis. Public health practitioners can partner with freshwater swimming sites to control Naegleria disease through various measures.
Step-by-step explanation:
Naegleria fowleri is a concern for public health because it can cause a rare but fatal brain infection called primary amoebic meningoencephalitis (PAM). This amoeba is commonly found in warm freshwater environments, such as lakes and hot springs, and can enter the body through the nasal passages. Once inside, it can travel to the brain and cause severe inflammation and destruction of tissue.
Public health practitioners can partner with freshwater swimming sites to control Naegleria disease by implementing measures to reduce the risk of exposure. This can include monitoring water quality, providing education on safe swimming practices, and promoting the use of nose clips or keeping the head above water to prevent water from entering the nasal passages.
