Kerala Battles Brain-Eating Amoeba: 23 Deaths from 104 Cases of Amoebic Encephalitis
  • The infection is caused by Naegleria fowleri, a free-living amoeba found in warm, stagnant freshwater sources.

  • The infection is caused by free-living amoebae such as Naegleria fowleri, Acanthamoeba, and Balamuthia mandrillaris, typically present in warm freshwater sources.

  • Health authorities are actively monitoring the outbreak and implementing measures to control the spread and prevent further fatalities.

  • A collaborative initiative emphasizes the interconnectedness of human, animal, and environmental health, enhancing Kerala’s surveillance, prediction, response, and long-term planning capabilities to combat the disease.

  • Kerala has reported 104 cases of amoebic encephalitis caused by the brain-eating amoeba Naegleria fowleri, resulting in 23 deaths, with Kollam and Thiruvananthapuram being the most affected districts.

  • An action plan employing a One Health approach was implemented in 2025 to improve prevention efforts, including scientific chlorination and ongoing safety measures across the state.

  • In 2024, the Kerala Health Department issued guidelines for the diagnosis and treatment of amoebic encephalitis to enhance patient outcomes.

  • The disease begins when contaminated water enters the nose, allowing the amoeba to reach the brain and cause severe inflammation, with symptoms like headache, fever, nausea, confusion, seizures, and hallucinations.

  • It typically occurs when individuals swim or bathe in contaminated water, leading to the amoeba invading the nasal passages and causing brain inflammation.

  • Diagnosis involves analyzing cerebrospinal fluid, and early medical intervention is critical for suspected cases.

  • Naegleria fowleri, also known as the brain-eating amoeba, is responsible for this rare but often fatal brain infection.

  • Preventive measures include avoiding swimming in stagnant or unclean water, especially when rinsing the nose, and using properly chlorinated pools.

  • Early medical treatment is essential, and individuals should avoid warm, stagnant water for swimming or nasal cleansing with sterile or boiled water.

  • Amoebic meningoencephalitis is a rare, often fatal brain infection caused by Naegleria fowleri.

  • Symptoms usually develop within 1 to 9 days of exposure and include severe headache, fever, nausea, vomiting, neck stiffness, and in severe cases, seizures and memory loss.

  • Naegleria fowleri is found in warm freshwater bodies and is not transmitted person-to-person, but through contact with contaminated water.
