Battling a Rare Brain-Eating Disease in Kerala

On the day when families in Kerala gathered to celebrate Onam, a festival of joy and togetherness, tragedy struck one family in Malappuram district. Forty-five-year-old Sobhana, a woman who worked bottling fruit juices, fell seriously ill. At first, she complained only of dizziness and high blood pressure. Doctors gave her medicine and asked her to rest. But her condition worsened quickly. She developed fever, shivering, and confusion. On September 5, the main day of Onam, she passed away.

The cause was shocking — an infection by Naegleria fowleri, known as the “brain-eating amoeba.”

What Is This Disease?

The brain-eating amoeba is a single-celled organism that normally lives in warm freshwater, like ponds and rivers. It feeds on bacteria. But when it enters the human body through the nose — usually while swimming — it can travel to the brain. There, it destroys brain tissue and causes a condition called primary amoebic meningoencephalitis (PAM).

This disease is extremely rare, but it is also extremely deadly. According to studies, around 95% of people who get infected die. Since 1962, only about 488 cases have been recorded worldwide, most of them in the United States, Pakistan, and Australia.

The Situation in Kerala

Kerala first started recording cases in 2016, usually just one or two a year. Almost all patients died. But this year has been very different. More than 70 people have been diagnosed, and 19 have died so far. Patients include people of all ages — from a three-month-old baby to a 92-year-old man.

Doctors and families in Kerala are shocked because the disease is so unusual. Many doctors may never see even one case in their entire career. In Sobhana’s case, her family only learned about the amoeba after her death.

Why Is It So Dangerous?

The biggest challenge is that the infection moves very fast. Early symptoms — like headache, fever, or dizziness — look similar to common illnesses. By the time doctors suspect something more serious, the amoeba may already be destroying brain tissue.

There is also no clear, reliable treatment. Some drugs have been tried, but most patients do not survive. A few recent cases in other countries have been treated successfully with a combination of strong medicines, but success is rare.

How Do People Get Infected?

The amoeba spreads through water entering the nose. It does not spread by drinking water. Most infections happen when people swim in lakes, ponds, or rivers with warm, still water. In some cases, using contaminated tap water for nasal cleansing has also led to infection.

Because the disease is so rare, health officials often struggle to track and prevent it. But experts suggest that avoiding swimming in untreated warm water, using nose clips, or keeping the head above water can reduce risk.

The Human Side of the Crisis

For families like Sobhana’s, the loss is unbearable. She was the breadwinner of her home, working long hours to support her family. Relatives say she was a strong, cheerful woman who never complained about her struggles. Her cousin, Ajitha Kathiradath, a social worker, said, “We were powerless to stop it. We learnt about the disease only after her death.”

Every death leaves behind a story of pain — parents losing children, children losing parents, and communities losing loved ones.

What Authorities Must Do

The sudden rise in cases in Kerala shows that more action is needed. Health departments should:

Spread Awareness: People must know that the amoeba exists and how it spreads. Simple information can save lives.

Test Water Sources: Regular checks of ponds, lakes, and swimming areas can help identify risk.

Improve Diagnosis: Hospitals must train doctors to recognize symptoms early, even though the disease is rare.

Research Treatment: More global research is needed to find effective medicines. With such a high death rate, every possible cure must be studied.

Looking Ahead

The brain-eating amoeba is not a new threat, but it has rarely caused large outbreaks. The rise of cases in Kerala should be taken as a warning. Warm weather, polluted water, and lack of awareness may all play a role.

While the disease is still uncommon, its impact is devastating for those affected. Preventing even one infection can save a family from tragedy.
