Key Facts About Amoebic Meningoencephalitis
- Amoebic Meningoencephalitis is a rare brain infection caused by free-living amoebae.
- There are two main types: Primary Amoebic Meningoencephalitis (PAM) and Granulomatous Amoebic Encephalitis (GAE).
- PAM is caused by Naegleria fowleri, known as the brain-eating amoeba.
- GAE is caused by Acanthamoeba, found in water bodies, soil, and dust.
- Since 1971, India reported only around two dozen cases until 2023.
- Kerala developed a special treatment protocol in 2024 to manage the disease.
- Symptoms include fever, headache, nausea, seizures, hallucinations, coma, and death if untreated.
Ecological and Social Impact in Kerala
The surge in Amoebic Meningoencephalitis cases in Kerala highlights the ecological and social challenges faced by the state. The warm tropical climate and poor water quality contribute to the proliferation of amoebae. This situation underscores the need for improved water management and public health strategies to align with India’s health and safety goals.
