“Naegleria fowleri is a microscopic single-celled living ameba that occurs naturally in the environment. This ameba can cause a very serious rare infection of the brain called primary amebic meningoencephalitis (PAM) that destroys brain tissue and is almost always fatal,” the DPBH release noted.
Symptoms can be mild at first, but they worsen quickly. Symptoms usually start about 5 days after infection (range 1–9 days) and can include headache, fever, nausea or vomiting. Later symptoms can include stiff neck, confusion, lack of attention to people and surroundings, loss of balance, seizures and hallucinations.
Primary amebic meningoencephalitis (PAM) is treated with a combination of drugs, often including amphotericin B, azithromycin, fluconazole, rifampin, miltefosine, and dexamethasone. These drugs are used because they are thought to be effective against Naegleria fowleri and have been used to treat patients who survived.
Last year, another Nevada boy died because of a brain-eating amoeba. Only 157 cases were reported from 1962 through 2022, according to the CDC. Only four of the patients survived in that period. The infection usually occurs in boys younger than 14, according to CDC data.
What is the prognosis (outlook) for people who are infected with brain-eating amoeba (Naegleria fowleri)? The outlook for someone who is infected with Naegleria fowleri is very poor. Even with treatment, most people die from this condition.
Cases of PAM have been recorded in South Australia, Western Australia, Queensland and New South Wales and in many countries throughout the world. N. fowleri is frequently found in the environment. It is believed that exposure to this organism is common, but illness is very rare.
Since it was first identified in 1965, only 19 infections have been reported in Australia. Infection can result in a rare form of meningitis (inflammation of the brain and lining around the brain) called primary amoebic meningoencephalitis (PAM).
Most Naegleria fowleri infections happen in young males, especially those 14 years old and younger. The reasons for this aren't clear. It's possible that young boys are more likely than others to participate in activities such as diving into the water and playing in the sediment at the bottom of lakes and rivers.
A cerebral abscess is an infection in your brain. It is a medical emergency that requires treatment right away. Symptoms can include headache, fever, changes in consciousness, confusion, neck stiffness, vomiting, seizures, weakness, trouble moving, and changes in vision.
Keep in mind that Naegleria fowleri infections are extremely rare. What may seem like PAM symptoms are more likely from an illness that's more common, such as bacterial meningitis.
Pneumococcal meningitis is the most common form of meningitis and is the most serious form of bacterial meningitis. The disease is caused by the bacterium Streptococcus pneumoniae, which also causes pneumonia, blood poisoning (septicemia), and ear and sinus infections.
For instance, an extreme immune response can cause a brain-swelling condition called encephalitis, which can lead to headaches, mental confusion and even seizures. “Another consequence of this over-activated immune response is the development of blood clots,” Bernard said.
When people first become sick from the virus, they may develop encephalitis — inflammation of the brain — causing confusion, difficulty concentrating, and memory problems. COVID also can trigger the onset of new psychological disorders such as severe depression or anxiety.
Since May 2022, there has been a global increase in mpox infections in multiple countries where the illness is not usually seen. Mpox was first reported in Australia May 2022. On 28 July 2022, Australia's Chief Medical Officer declared monkeypox to be a Communicable Disease Incident of National Significance.
So far, N. fowleri has been found in drinking water distribution systems in Australia, the United States and Pakistan. The good news is that you cannot become infected by drinking a glass of water containing the amoeba.
Wear nose clips when swimming in warm freshwater.
"Because brain-eating amoebas enter the body through the nose, blocking that entry point can protect you against this threat," says Dr. Sebti.
Answer and Explanation: The 'brain-eating amoeba,' which is the species Naegleria fowleri, must be introduced to the human body through the nose. So, unless you have contaminated bottle water that you sniff up your nose, it is extremely unlikely that you will be exposed to the brain-eating amoeba through bottled water.
PHYSICAL INACTIVATION: Heating water to 50ºC for 5 minutes will kill all forms of the amoebae 17. Both amoeba and cysts can tolerate temperature of 65ºC for 1-3 minutes and temperatures below 20ºC inhibit reproduction 15. Degradation occurs when temperatures reach below 10ºC. Dehydration is lethal to N.
It is commonly called the “brain-eating ameba” because it can cause a brain infection when water containing the ameba goes up the nose. Only about three people in the United States get infected each year, but these infections are usually fatal. Initial symptoms can include headache, fever, nausea, or vomiting.
Naegleria does not occur in sea water. You cannot get Naegleria from a properly cleaned, maintained and chlorinated swimming pool. The organism was first identified in South Australia during the 1960s.

"This headache was different. It felt more like — the description that I kept saying at the hospital was that it felt like there was a smooth rock on top of my head, and someone was pushing it down," Deleon later told Click Orlando.
In very rare instances, Naegleria fowleri has been found in inadequately chlorinated water, including in pools, splash pads, and a surf park. Naegleria fowleri is not found in salt water, such as the ocean.
PAM can be diagnosed in the laboratory by detecting Naegleria fowleri organisms, nucleic acid, or antigens in a patient's cerebrospinal fluid (CSF) or brain tissue.
