Karnataka Issues Advisory On Naegleria Fowleri Risk For Pilgrims

Karnataka has released a health advisory for Sabarimala pilgrims following confirmed cases of Amoebic meningoencephalitis in Kerala. The advisory urges travellers to adopt safety measures against “Naegleria fowleri”, the rare but dangerous “brain-eating amoeba” found in warm freshwater sources.

Health Alert Triggered By Cases In Kerala

The advisory was issued after recent infections were reported in Kerala, prompting Karnataka’s Health and Family Welfare Services to act. Officials emphasised the importance of awareness among pilgrims due to frequent exposure to natural water bodies during the pilgrimage season. The communication highlights the seriousness of the infection, which remains rare but often fatal.

Nature Of The Brain-Eating Amoeba

Naegleria fowleri thrives in warm freshwater, including ponds, stagnant water, lakes, and inadequately maintained swimming pools. While it does not spread from person to person or through drinking water, the amoeba can enter the body through the nose. Once inhaled, it may travel to the brain and cause Amoebic meningoencephalitis, a rapidly progressing and life-threatening condition.

Precautionary Measures For Pilgrims

The advisory urges pilgrims to avoid allowing water into the nose while bathing in freshwater bodies. Use of nose clips or covering the nose tightly is recommended during ritual bathing or while entering stagnant water areas. Travellers are asked to remain cautious throughout the Yatra, particularly in warm or untreated water sources.

Exam Oriented Facts

• Naegleria fowleri infection occurs only when contaminated water enters the nose.
• The disease Amoebic meningoencephalitis progresses rapidly and is often fatal.
• The amoeba is commonly found in warm freshwater, not seawater.
• There is no human-to-human transmission of this infection.

Symptoms And Immediate Medical Attention

Pilgrims have been advised to seek emergency care if symptoms appear within seven days of freshwater exposure. Warning signs include fever, severe headache, nausea, vomiting, stiff neck, confusion, or behavioural changes. Health authorities stress that early detection and prompt hospital consultation are vital for improving survival chances.
