Inadequate Water Sanitation System To Blame

FDOH: Case of rare brain-eating amoeba found in Hillsborough County

Cope noted that an inadequate water sanitation system at the park is the likely reason for the presence of the deadly amoeba.

The park relies on ultraviolet radiation and chlorine to clean the water. Under normal conditions, this would kill Naegleria, but because the parks man-made bodies of water are designed to look natural, they tend collect dirt and debris from the river which can interfere with the sanitation process, according to Cope.

The chlorine reacts with all that debris and is automatically consumed so that it is no longer present to deactivate a pathogen like Naegleria and the same is true about UV light, she said.

Only three other park systems in the U.S. are exempt from being regularly tested for pathogens because they are seen more as a river or natural systems rather than man-made bodies of water, Cope said.

Mecklenburg County Medical Director Dr. Stephen Keener said at the press conference that while the infection is extremely rare, changes to the filtering system may be forthcoming.

He added that there is no concrete evidence that an increased level of the amoeba creates a heightened risk of humans contracting it.

What Is The Prognosis Of A Naegleria Fowleri Infection

The prognosis for infected patients is very poor, as 99% of infections are fatal despite intensive treatment. The rare survivor may have residual neurological problems, such as seizure disorders.

  • There is the reason for hope, however, if treatment is started immediately with a regimen that includes miltefosine. At least two cases in recent years were cured with rapid diagnosis and prompt, intensive therapy that included miltefosine. Both have had few residual problems.
  • This is the best reason for providers and the public to be aware of the risk factors and make the diagnosis quickly.
  • Otherwise, the easiest and cheapest treatment is prevention.

How Is Primary Amebic Meningoencephalitis Diagnosed

PAM can be difficult to diagnose. The disease progresses quickly, but it can take weeks to identify the ameba in the laboratory. Current diagnostic tools include evaluating cerebrospinal fluid, brain imaging, and culture in the laboratory. New detection tests are under development.

When taking part in water-related activities, you can take actions to reduce the risk of water going up the nose and lowering the chances that;Naegleria fowleri;may be in the water. These actions could include:

  • Hold your nose shut, use nose clips, or keep your head above water when taking part in water-related activities in bodies of warm freshwater.
  • Avoid water-related activities in warm freshwater during periods of high water temperature and low water levels.
  • Avoid digging or stirring up sediment while taking part in water-related activities in shallow, warm freshwater areas.

Child Dies From Brain

RALEIGH, N.C. A child who died last week had developed an illness caused by a rare brain-eating amoeba they contracted while swimming in a pond in central North Carolina, the state health department said.

The Centers for Disease Control and Prevention confirmed the childs illness was caused by Naegleria fowleri, an amoeba found in freshwater. It can be fatal if forced up the nose, as can occur during jumping into water, diving, water-skiing or other water activities.

The North Carolina Department of Health and Human Services did not specify where the pond was located just that it was on the childs familys property in the central part of the state.

Our heart-felt condolences and sympathies are with the family and friends of this child, said State Epidemiologist Zack Moore, M.D. Although these infections are very rare, this is an important reminder that this amoeba is present in North Carolina and that there are actions people can take to reduce their risk of infection when swimming in the summer.

NCDHHS said symptoms of naegleria fowleri infection start with severe headache, fever, nausea and vomiting and progress to stiff neck, seizures and coma and can lead to death.

These rare infections usually occur when it is hot for prolonged periods of time, which results in higher water temperatures and lower water levels. Naegleria fowleri grows best at higher temperatures up to 115°F.

How Does Infection With Naegleria Fowleri Occur

Naegleria fowleri;enters the body through the nose and travels to the brain, where it destroys brain tissue and causes swelling and death.;Naegleria fowleri;typically enters the nose when people go swimming or diving in bodies of warm freshwater, such as ponds, lakes and rivers. Very rarely, people can become infected by submerging their heads during religious practices or irrigating their sinuses using contaminated tap water.

No one has reported a;Naegleria fowleri;infection due to drinking contaminated water, or swimming in a properly cleaned, disinfected and maintained pool.

Where Is Naegleria Fowleri Found

Naegleria fowleri;has been identified in freshwater specimens worldwide.;Naegleria fowleri;is not found in salt water. In the United States, the majority of;Naegleria fowleri;infections have occurred after swimming in freshwater located in southern states. In 2012, infection with;Naegleria fowleri;occurred in a child after swimming in a Minnesota lake. The Illinois Department of Public Health has not received any reports of;Naegleria fowleri;infection.

How Is It Treated

Because the infection is so rare, there are limited studies and clinical trials regarding effective treatments for Naegleria infection. Most treatment information comes from of studies within a laboratory or through case studies.

One promising treatment is the antifungal medication amphotericin B. It can be given or injected into the area around your spinal cord.

Another new drug called miltefosine appears to be useful for treating Naegleria infections.

Additional medications that may be given to treat Naegleria infection include:

  • , an antifungal medication

Infection with Naegleria is very rare, but its always a good idea to take a few precautions when youre spending time in water.

Heres a look at some tips to reduce your risk:

  • Avoid swimming in or jumping into freshwater lakes, rivers, or streams, especially during warm weather.
  • If you do plan to swim in freshwater, try to keep your head above water. Consider using nose clips or holding your nose shut with your fingers.
  • Try not to disturb or kick up the sediment when swimming or playing in freshwater.
  • Make sure to only swim in pools that have been properly disinfected.

By now, many of us have experienced this sentiment can 2020 get any worse? But recent reports of a childs death from Naegleria fowleri , commonly called the brain-eating amoeba, from contaminated water in a southeast Texas community proves that it can and just did. The Water Quality & Health Council has written about this amoeba before, including to highlight the role of chlorine-based water disinfection to help prevent infections, which while incredibly rare, are almost always fatal.

Naegleria fowleri Basics

Naegleria is a genus of free-living, single-celled amoeba found around the world. They feed on bacteria and other microbes in the environment. Although there are almost 50 separate species of Naegleria, only Nfinfects humans.

Did You Say Brain-Eating Amoeba?

Most cases of PAM are in children and young adults as a result of vigorous recreational water contact such as diving, splashing, and kayaking. Even if water containing the amoeba does go up the nose, the chance of a person contracting PAM is still extremely small. You cannot get infected from swallowing water containing Nf amoeba and PAM cannot be spread from person to person.

Cdc: High Levels Of Brain

  • Unusually high levels of brain-eating amoeba have been found at a North Carolina park.

An unusually high level;of a brain-eating amoeba was detected at a North Carolina water park where an Ohio teen became infected and later died, according to the Center for Disease Control and Prevention.

Eleven samples were taken from the U.S. National Whitewater Center in Charlotte and all tested positive for Naegleria fowleri, officials with the CDC announced this week at a press conference.

Four of the samples collected from the nearby Catawba River tested negative for the pathogen while a sample taken from the riverbed also tested positive.

Our findings here are significant, Dr. Jennifer Cope, an infectious disease physician at the CDC, told CNN. We saw multiple positive samples at levels weve not previously seen in environmental samples.

Brain Eating Amoeba Symptoms: Stage 2

The symptoms in this stage begin after 1 to 12 days following the symptoms in stage 1 are felt. These symptoms include stiff neck, seizures, hallucinations, coma and changed mental status.

The progression of the condition is too quick that the cause is not identified until after the person dies. The condition only indicates that waters sports are not only dangerous, but also deadly. It is not because of what may happen during the water activity, but of brain eating amoeba that may possible be lurking underwater. However, even with this possible danger, people still love performing water sports. It cannot really be helped since these are thrilling activities. But, it would help to take extra caution. If there have been past reports that involve death linked to the waters of the place, it will be better to avoid going there.

The presence of these organisms in the bodies of water does not come as a threat to people. That is because people have no knowledge that it is infected. So, to avoid being infected by these organisms and prevent brain eating amoeba symptoms, be sure to bring nose clips when performing water sports.

Texas City Where Boy 6 Died Of Brain

A Houston-area city where a 6-year-old boy died of a brain-eating amoeba will purge its water system for 60 days to ensure it is safe for residents.

The death earlier this month of Josiah McIntyre of Lake Jackson, Texas, from the deadly microbe prompted an investigation that preliminarily identified the amoeba in three of 11 water samples taken in the city.

Now, the local water utility is trying to purge any old water so the system can be disinfected and replaced with fresh water.

Well be doing that for a 60-day period, said City Manager Modesto Mundo of the community of about 26,000 residents 55 miles south of Houston.

Lake Jackson residents were initially warned over the weekend not to use tap water for anything but flushing toilets, but are now being advised to boil tap water before using it for drinking or cooking and to avoid getting tap water up the nose.

Naegleria fowleri “usually infects people when contaminated water enters the body through the nose” and typically occurs when people go swimming in warm freshwater places, like lakes and rivers, the Centers for Disease Control and Prevention said in guidance on its website. “Once the ameba enters the nose, it travels to the brain,” where it causes a condition that is usually fatal.

“You cannot get infected from swallowing water contaminated with Naegleria,” the CDC said.

We found out that it was, most likely, this amoeba that was causing all of these symptoms, Castillo said.

Naegleria loves very warm water. It can survive in water as hot as 113 degrees Fahrenheit.

These amoebas can be found in warm places around the globe. N. fowleri is found in:

  • Warm lakes, ponds, and rock pits
  • Mud puddles
  • Warm, slow-flowing rivers, especially those with low water levels
  • Untreated swimming pools and spas
  • Untreated well water or untreated municipal water
  • Hot springs and other geothermal water sources
  • Thermally polluted water, such as runoff from power plants
  • Aquariums
  • Soil, including indoor dust

Naegleria can’t live in salt water. It can’t survive in properly treated swimming pools or in properly treated municipal water.

Most cases of N. fowleri disease occur in Southern or Southwestern states. Over half of all infections have been in Florida and Texas.

What Is A Brain

Amoebas are single-celled organisms. The so-called brain-eating amoeba is a species discovered in 1965. It’s formal name is Naegleria fowleri. Although first identified in Australia, this amoeba is believed to have evolved in the U.S.

There are several species of Naegleria but only the fowleri species causes human disease. There are several fowleri subtypes. All are believed equally dangerous.

N. fowleri is microscopic: 8 micrometers to 15 micrometers in size, depending on its life stage and environment. By comparison, a hair is 40 to 50 micrometers wide.

Like other amoebas, Naegleria reproduces by cell division. When conditions aren’t right, the amoebas become inactive cysts. When conditions are favorable, the cysts turn into trophozoites — the feeding form of the amoeba.

What Are The Symptoms Of Brain Eating Amoeba

The infection commonly occurs when people go swimming or diving in fresh, warm water places such as lakes or rivers.

In rare cases, infections can occur from swimming in poorly chlorinated pools and consuming contaminated tap water.

Symptoms of contracting Naegleria fowleri present themselves in stages.

Stage one includes severe frontal headache, fever, nausea, vomiting.

Stage two includes a stiff neck, seizures, altered mental status, hallucinations, and a possible coma.

Every few years, a parasite commonly referred to as Brain-Eating Amoeba starts to attract attention for its sudden and often fatal impact on humans.;According to the Center for Disease Control and Prevention , only three of the 138 people known to be infected survived. From 2006 to 2015, 37 infections were reported and all but two were fatal. The good news is amoeba infection, and the resulting illness, are rare and often avoidable.

What is Brain-Eating Amoeba?

The term amoeba describes;hundreds of organisms and can also be spelled ameba.

Naegleria fowleri;is the;species commonly referred to as Brain-Eating Amoeba.;Naegleria fowleri is;a single-celled organism that loves warm freshwater, such as the lakes and ponds, found in Central Florida. Brain-Eating Amoeba is;found worldwide.

The often-fatal illness caused by Brain-Eating Amoeba;is Primary Amoebic Meningoencephalitis . Fortunately, PAM is exceedingly rare in Florida and the rest of the United States.

How Do Brain-Eating Amoebas Infect People?

Brain-Eating Amoeba infects people when contaminated water travels up the nose. This usually occurs as people take part in freshwater recreational activities. After an amoeba enters the body, through the nose, it travels to the brain where it can cause Primary Amoebic Meningoencephalitis . PAM destroys brain tissue and can cause swelling and death.

A deadly brain-eating amoeba was discovered in the mains water supply of a Texas town.

Residents of Brazoria, Texas, and the surrounding area were banned from drinking or using tap water and only allowed to flush their toilets.

The amoeba, known as naegleria fowleri, prompted a health-warning from authorities on Friday which impacted 58,000 people.

Health experts say that the amoeba affects people when contaminated water enters the body through the nose.

  • FOLLOW US ON:

Texas officials on Saturday lifted the warning for eight Houston-area communtites to stop using tap water because it might be tainted with a deadly brain-eating microbe. One city remained under a boil water notice.

The Texas Commission on Environmental Quality warned the Brazosport Water Authority late Friday of the potential contamination of its water supply by naegleria fowleri.

The authority initially warned eight communities not to use tap water for any reason except to flush toilets, but on Saturday it lifted that warning for all communities. The advisory also was canceled for two state prisons and Dow Chemicals massive Freeport works.

A water advisory for the residents was issued by the Texas Commission on Environmental Quality that advised not to use any water as it contained Naegleria fowleri, a brain-eating amoeba. The microbe was found in the water supply on Friday, a CNN report said.

“The Texas Commission on Environmental Quality at the direction of the Governor’s Office is working with Brazosport Water Authority to resolve the issue as quickly as possible,” the advisory reads.

Earlier this month, 6-year-old Josh McIntyre died after contracting the microbe.

According to the Centers for Disease Control and Prevention, the brain-eating amoeba is commonly found in soil, warm lakes, rivers, and hot springs. It can also be found in poorly maintained or unchlorinated pools and in warm water discharge from industrial plants.

What Is An Amoeba

Before we get too far-gone with Naegleria fowleri and the infection it can cause, were going to break down the basic science of what an amoeba is and how it can cause such a horrific infection in humans.

All living things can be divided into two groups based on the complexity of their cell structure prokaryotes and eukaryotes. Bacteria and Archaea are prokaryotes, while other living organisms have highly organized cell structures and are eukaryotes.

Although amoebas are simple organisms, biologically speaking, they can often cause infections in humans, such as the disease primary amebic meningoencephalitis . This disease causes a brain infection that leads to the destruction of brain tissue, which is often fatal. Early symptoms include fever and vomiting, which progress to more severe symptoms such as hallucinations and coma, and can ultimately lead to death within about five days. Luckily, it is not contagious and cannot be spread from person-to-person.

Even though the infection is rare, it can still happen. So, if you happened to be vacationing somewhere and this amoeba swims up your nose and causes a rare infection, is there a way to survive?
