Health Minister Veena George has urged the public to remain vigilant as the risk of amoebic meningoencephalitis may increase during the summer season. Warm temperatures and stagnant water conditions can create a favourable environment for disease-causing microorganisms.
Precautionary Measures to Reduce Risk
To minimise exposure, the minister advised people to avoid bathing or washing their face in contaminated water. In addition, individuals should maintain clean water sources, regularly chlorinate wells and storage tanks as per health guidelines, and ensure proper sanitation of swimming pools, spas, and water parks.
Furthermore, she recommended avoiding swimming or diving in stagnant water bodies. Using a nose clip while swimming and avoiding unboiled or untreated water for nasal rinsing are also essential preventive steps. Equally important, the public should refrain from dumping waste into water bodies and ensure that water storage tanks are cleaned every three months.
Strengthening Public Health Surveillance
Meanwhile, the health department has intensified monitoring efforts across the state. The minister emphasised that authorities must regularly assess water quality in public spaces and take necessary corrective actions. At the same time, individuals experiencing symptoms should seek immediate medical attention.
Recognising Early Symptoms
Early detection remains critical. Key symptoms of amoebic meningoencephalitis include sudden high fever, severe headache, vomiting, neck pain, sensitivity to light, loss of consciousness, and visual disturbances. Prompt medical intervention can significantly improve outcomes.
Diagnostic Facilities and Medical Preparedness
As reported by TOI, the minister highlighted that all medical colleges in Kerala are equipped to detect amoebas through their microbiology departments. Additionally, advanced diagnostic facilities for species identification and molecular testing are available at the public health laboratory in Thiruvananthapuram, the institute in Thonnakkal, and the Kozhikode medical college microbiology department.
Understanding the Disease and Risk Factors
Amoebic meningoencephalitis is caused by organisms such as Naegleria fowleri and Acanthamoeba, which are commonly found in warm lakes, ponds, and polluted water bodies. These organisms enter the body through the nose and can attack the brain.
Moreover, individuals with weakened immune systems face a higher risk, particularly from Acanthamoeba infections that may enter through open wounds and affect the brain and nervous system. Therefore, they should clean wounds only with clean and treated water.
Kerala’s Proactive Response and Improved Outcomes
Importantly, the state has implemented strong measures to improve early detection and treatment. According to the minister, while global mortality rates remain extremely high—around 99% for Naegleria fowleri and 70–90% for Acanthamoeba—Kerala has successfully reduced mortality to 24%.
She further noted that the state conducted expert workshops, introduced a dedicated treatment protocol, and collaborated with the Indian Council of Medical Research on research initiatives. These efforts have enabled earlier diagnosis and more effective management of cases.
A Call for Awareness and Preventive Action
Overall, the advisory underscores the importance of public awareness, hygiene, and timely medical care. By adopting preventive measures and recognising early symptoms, individuals can significantly reduce the risk of this rare but serious infection.
