Karnataka Issues Advisory on Naegleria Fowleri Risk for Pilgrims

Karnataka’s Health and Family Welfare Services Department has issued a formal advisory for Sabarimala pilgrims after Kerala reported multiple cases of Amoebic meningoencephalitis , a rare but severe infection caused by the Naegleria fowleri amoeba. With lakhs of devotees travelling through freshwater areas during the pilgrimage season, the advisory aims to enhance public awareness and minimise exposure risks.

Trigger Behind the Alert

The advisory follows confirmed infections in Kerala, prompting precautionary action from Karnataka amid increased cross-border pilgrim movement. Officials emphasise that although Naegleria infections are extremely rare, the condition is often fatal, making preventive measures essential. The government highlighted the importance of staying cautious around natural water sources commonly visited during rituals.

Understanding the ‘Brain-Eating Amoeba’

Naegleria fowleri naturally occurs in warm freshwater such as ponds, untreated lakes, hot springs and poorly maintained swimming pools. The amoeba does not spread through drinking water and cannot transmit between humans . Infection occurs only when contaminated water enters the nose , allowing the organism to reach the brain and trigger fast-progressing Amoebic meningoencephalitis.

Safety Measures for Pilgrims

Authorities urge pilgrims to avoid submerging their heads in warm freshwater bodies and to use nose clips or cover their noses tightly during holy dips or ritual baths. Particular caution is advised in stagnant or untreated water. Devotees are encouraged to remain vigilant throughout the Yatra, especially during early morning or daytime bathing when water temperatures are higher.

Symptoms and Need for Urgent Care

Pilgrims should seek immediate medical attention if symptoms such as severe headache, fever, vomiting, stiff neck, confusion or behavioural changes occur within a week of exposure. Early diagnosis offers the best chance of survival.

Exam-Oriented Facts

• Naegleria fowleri infects only via water entering the nose , not by drinking.

• Causes Amoebic meningoencephalitis , a rare but often fatal condition.

• Thrives in warm freshwater , not seawater.

• No human-to-human transmission occurs.
