Introduction
With rising summer temperatures, rare but dangerous infections like the brain-eating amoeba (Naegleria fowleri) are making headlines across India. Though extremely rare, this infection is often fatal and needs urgent awareness. At Supreme Hospitals, our neurologists and emergency care teams want to help you understand the risks, symptoms and most importantly, how to stay safe.
What Is a Brain-Eating Amoeba?
Naegleria fowleri is a microscopic, single-celled organism that thrives in warm freshwater environments such as lakes, rivers, hot springs and even poorly maintained swimming pools. It is not harmful if swallowed, but it can become deadly when contaminated water enters the body through the nose typically during activities like swimming, diving, or other water sports. Once it gains access through the nasal passages, the amoeba can quickly migrate to the brain, making it one of the most aggressive and dangerous free-living microorganisms known to medical science.
How Does It Affect the Human Body
els along the olfactory nerve to the brain, where it causes a rare and devastating brain infection known as Primary Amoebic Meningoencephalitis (PAM). This infection leads to inflammation and destruction of brain tissue, resulting in severe neurological damage. The disease progresses rapidly, often within days and is almost always fatal if not diagnosed and treated in the very early stages. Most patients succumb to the infection within one to two weeks of symptom onset, underscoring the critical need for immediate medical attention at the first sign of symptoms.
Common Symptoms to Watch For (2-15 days after exposure):
- Severe headache
- Fever
- Nausea or vomiting
- Stiff neck
- Sensitivity to light
- Confusion or hallucinations
- Loss of balance or seizures
These symptoms progress rapidly. Immediate medical attention is crucial.
Who Is at Risk?
- People swimming in warm freshwater during summer
- Children and teenagers who play in lakes or rivers
- Individuals using untreated water for nasal rinsing or religious rituals
Is It Common in India?
Cases are very rare, but a few have been reported in recent years. Due to increased temperatures and water exposure, experts advise extra caution, especially in southern states like Tamil Nadu.
How to Prevent Infection
- Avoid swimming in warm freshwater bodies during hot weather
- Use nose clips when diving into lakes or rivers
- Ensure pools are properly chlorinated and maintained
- Never use untreated tap water for nasal rinsing; always use boiled or sterile water
