Living in warm, shallow, freshwater environments like lakes, rivers, and hot springs Naegleria fowleri is a type of amoeba species found worldwide. In soil, it also thrives. Because it does not require a host to survive, it is regarded as a free-living organism.
A fourteen-year-old boy from Kerala, India, was killed by a rare brain-eating amoeba in the Kozhikode district. State health officials claim that the boys free-living amoeba infection was discovered in the tainted waters.
In the previous three months, the deadly infection has been the cause of three deaths. The boy was swimming in a small pond when he contracted the virus, according to the health department. Immediate preventive action has been taken in response to the incident.
Previously, on May 21 in Malappuramon, a five-year-old girl died from the virus, and on June 25 in Kannur, another thirteen-year-old girl perished.
The disease known as primary amoebic meningoencephalitis (PAM) affects those who are infected by this amoeba. The central nervous system is severely infected with PAM, which is nearly always lethal.
The most typical way to contract this kind of amoeba is through the ingestion of contaminated water in the nasal cavity. The amoeba then travels to your brain. This typically occurs when engaging in aquatic sports like water skiing, diving, or swimming in contaminated water. In very rare instances, poorly chlorinated swimming pool water or heated tap water may contain bacteria.
Water contaminated by an infection cannot infect you.
However, in more recent years, a few cases have occurred in northern states during extremely hot weather. The shifting geographic distribution of infections may be a result of climate change.
Research is being conducted to challenge the actual rarity of the Naegleria fowleri infection. Antibodies against the amoeba are present in certain individuals, suggesting that they have been infected and managed to survive. Certain cases of deaths previously linked to meningitis have now been reclassified as amoeba-caused brain deaths (Naegleria fowleri).
The following are some of the abrupt and severe initial signs and symptoms of primary amoebic meningoencephalitis (PAM).
The fatality rate is higher than 97%, even with treatment.
The Naegleria fowleri amoeba enters your brain through your nasal cavity, which is how the infection happens. If you breathe in any contaminated water, it could enter your body. A warm freshwater environment, such as hot springs or geothermal water, is typically home to amoeba life.
Inhaling contaminated dust can also spread the infection.
Other reported cases of brain-eating amoeba (Naegleria fowleri) infections have been linked to people using tap water to rinse their noses with neti pots or other devices instead of distilled or sterilized water.
Following amoeba exposure, symptoms take two to fifteen days to manifest.
Can I get infected with brain-eating amoeba (Naegleria fowleri) from being around someone who has it?
No. No cases of the infection spreading from person to person have been discovered. Studies are being conducted to determine whether organ or tissue donation can spread the infection.
A doctor may advise a spinal tap, also called a lumbar puncture, if they believe you may have been infected with a brain-eating amoeba (Naegleria fowleri). This procedure allows the doctor to check your cerebrospinal fluid (CSF) for the organism.
A brain biopsy may also be suggested by your physician. In order to detect the amoeba during this process, a tissue sample will be taken and examined under a microscope.
The antifungal amphotericin B is the preferred treatment for primary amoebic meningoencephalitis (PAM), which is caused by an infection with brain-eating amoeba (Naegleria fowleri). Fluconazole, rifampin, amphotericin B, and a medication known as miltefosine were among the medications used to treat some survivors in North America. Sandflies carry the parasitic disease leishmaniasis, which can be treated with the drug miltefosine.
When brain swelling is treated by cooling the body to below-normal temperature and receiving early diagnosis and treatment with the prescribed drugs, the best outcomes (in two children who recovered completely) are achieved.
Despite the extreme rarity of the condition, prevention can be crucial due to its extremely poor prognosis. Points to keep in mind are as follows:
Tell your healthcare provider where you have been if you experience fever or headaches after entering warm freshwater.
A person with a Naegleria fowleri infection has a very bad prognosis. The majority of those with this illness pass away even with treatment. Usually, a week or ten days after the onset of symptoms and signs, a coma is followed by death.
Consult a physician or head straight to the emergency room if you develop a fever or headache after irrigating your nasal passages with tap water or after engaging in physical activity in a warm body of freshwater. The brain-eating amoeba (Naegleria fowleri) infection must be identified and treated as soon as possible.
