While quenching your thirst with a glass of tap water, enjoying your morning shower or swimming in a pool, you most likely are, at one time or another, aware of the chlorine used to disinfect your municipal water. Although its distinctive aroma may be unpleasant to some, it is an indication that your water supply is being adequately treated to stave off harmful or deadly microorganisms. Chlorine is widely credited with virtually eliminating outbreaks of waterborne disease in the United States and other developed countries.
Frequently Asked Questions What is Naegleria? Naegleria is an ameba single-celled living organism commonly found in warm freshwater for example, lakes, rivers, and hot springs and soil. Only one species type of Naegleria infects people: How Waterborne diseases and bacteria in tap infection with Naegleria fowleri occur?
You cannot get infected from drinking water contaminated with Naegleria. You can only be infected when contaminated water goes up into your nose. Naegleria fowleri infects people when water containing the ameba enters the body through the nose. This typically occurs when people go swimming or diving in warm freshwater places, like lakes and rivers.
The Naegleria fowleri ameba then travels up the nose to the brain where it destroys the brain tissue. You cannot be infected with Naegleria fowleri by drinking contaminated water. In very rare instances, Naegleria infections may also occur when contaminated water from other sources such as inadequately chlorinated swimming pool water or contaminated tap water enters the nose, for example when people submerge their heads or cleanse their noses during religious practices, and when people irrigate their sinuses nose using contaminated tap water.
Naegleria fowleri has not been shown to spread via water vapor or aerosol droplets such as shower mist or vapor from a humidifier.
Where is Naegleria fowleri found? Naegleria fowleri is found around the world. In the United States, the majority of infections have been caused by Naegleria fowleri from freshwater located in southern-tier states.
The ameba can be found in: Soil Naegleria fowleri is not found in salt water, like the ocean. In what water temperature does Naegleria fowleri cause infection? Naegleria fowleri is a heat-loving thermophilic organism. It is less likely to be found in the water as temperatures decline.
The ameba can be found in lake or river sediment at temperatures well below where one would find the ameba in the water. What is the source of food for Naegleria fowleri? Naegleria fowleri eats other organisms like bacteria found in the sediment in lakes and rivers. Can I get a Naegleria fowleri infection from a disinfected swimming pool?
You cannot get a Naegleria fowleri infection from a properly cleaned, maintained, and disinfected swimming pool. How common are Naegleria fowleri infections in the United States?
In the 10 years from to34 infections were reported in the U. Of those cases, 30 people were infected by recreational water, 3 people were infected after performing nasal irrigation using contaminated tap water, and 1 person was infected by contaminated tap water used on a backyard slip-n-slide.
Rare Disease Act of defined a rare disease as affecting less thanpeople in the U. When do Naegleria fowleri infections most commonly occur?
While infections with Naegleria fowleri are rare, they occur mainly during the summer months of July, August, and September. Infections are more likely to occur in southern-tier states, but can also occur in other more northern states.
Infections usually occur when it is hot for prolonged periods of time, which results in higher water temperatures and lower water levels.
Can infection be spread from one person to another? Naegleria fowleri infection cannot be spread from one person to another. What are the symptoms of Naegleria fowleri infection? Naegleria fowleri causes the disease primary amebic meningoencephalitis PAMa brain infection that leads to the destruction of brain tissue.
In its early stages, symptoms of PAM may be similar to symptoms of bacterial meningitis. Initial symptoms of PAM start about 5 days range 1 to 9 days after infection. The initial symptoms may 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.
After the start of symptoms, the disease progresses rapidly and usually causes death within about 5 days range 1 to 12 days.
What is the actual mechanism of death from Naegleria fowleri infection?Some people are drinking untreated water on purpose, The New York Times reported Friday.

Although parasitic infections are common throughout the world, most clinicians are inexperienced in the diagnosis and treatment of these diseases. Legionella is a genus of pathogenic Gram-negative bacteria responsible for a serious disease known as legionellosis, which is transmitted via inhalation of this pathogen in aerosol form.
There are two forms of legionellosis: Legionnaires' disease, which causes pneumonia-like symptoms, and Pontiac fever, which causes influenza-like symptoms.
