The Florida Department of Health issued a statement at the end of last month that a Florida man died of Naegleria fowleri, commonly known as the “brain-eating amoeba” (brain-eating amoeba). As for the infection, the authorities said that they are still investigating the cause of the infection in this case, and the identity of the deceased has not been disclosed. Florida public health authorities reminded residents not to rinse their noses with tap water, while emphasizing that drinking tap water is fine.
According to the Centers for Disease Control and Prevention (CDC), Negril fowleri is a single-celled organism that can survive in soil and freshwater all over the world. It grows and reproduces most easily in high temperature, so the most common infection cases occur in summer. In some cases, the infection occurred while swimming in warm lakes or rivers .
Overall, cases of N. fowleri infection are fairly rare and only occur after contaminated water enters the sinuses.
The Florida Department of Health emphasized that drinking tap water “cannot” be infected.
Authorities are urging people to rinse their nasal passages with distilled or sterile water, and sinus rinse bottles (neti pots) are common.
“Tap water should be boiled for at least one minute and cooled before being used to clean sinuses,” the release said.
According to CDC data, three cases of Negril fowleri infection were reported last year, including Iowa, Nebraska , and Arizona, all of which had been exposed to fresh water. Report three cases.
Last year, a Missouri resident was infected in Iowa after swimming at Lake of Three Fires in Taylor County in June, which was temporarily closed after the patient was diagnosed.
In Nebraska, a child was infected after swimming in the Elkhorn River in Douglas County in August. The child died within 10 days of infection. .
Florida authorities therefore also reminded children not to let children play with hoses or sprinklers unsupervised, because they may accidentally spray water up their noses. 
Symptoms of Naegleria fowleri infection include headache, fever, nausea, loss of balance, disorientation, seizures, and neck stiffness. The disease progresses rapidly after the onset of symptoms, and patients usually die within 18 days.
