Rise in Rare Brain-Eating Amoeba Cases: Causes and Prevention

Overview of the Brain-Eating Amoeba Cases

Kerala's health department has issued an alert in the Kjuko district following three consecutive cases of primary amebic meningoencephalitis (PAM), a rare but deadly brain infection caused by the amoeba Naegleria fowleri. The first recorded case of PAM in India was in 1971, with Kerala reporting its first case in 2016.

What is Primary Amebic Meningoencephalitis (PAM)?

• Cause: Naegleria fowleri, commonly known as the brain-eating amoeba.
• Habitat: This free-living amoeba thrives in warm freshwater bodies and soil.
• Transmission: It enters the human body through the nose, typically during swimming or diving in contaminated warm freshwater. For more information on how pathogens affect human health, check out Understanding Pollution, Pathogens, and Human Health.
• Pathology: Once inside, it travels to the brain, destroying brain tissue and causing severe inflammation and swelling.
• Contagion: The infection does not spread from person to person.

Symptoms and Treatment

• PAM progresses rapidly and is often fatal.
• Treatment involves a combination of drugs, such as miltefosine. For a deeper understanding of treatment challenges for rare diseases, see Understanding Tay-Sachs Disease: Causes, Symptoms, and Management.
• Despite treatment, the survival rate is extremely low, with a death rate of approximately 97%.

Important Facts

• The infection is rare but highly lethal.
• Early diagnosis and treatment are critical but challenging. For insights into neurological conditions and their management, refer to Understanding CTE: The Hidden Danger in Sports.

Practice Question

Consider the following statements about Naegleria fowleri:

1. It enters the human body through the nose, usually during swimming in warm freshwater.
2. The infection can spread from one person to another through direct contact.

Which of the statements is correct?

• A) Only statement 1
• B) Only statement 2
• C) Both statements 1 and 2
• D) Neither statement 1 nor 2

Answer: Statement 1 is correct; statement 2 is false.

Conclusion

Stay informed about water safety, especially when swimming in warm freshwater bodies. Awareness and preventive measures can reduce the risk of this rare but deadly infection.
