Increase in ‘brain-eating’ amoeba cases raises alarm in Kerala, India.

Health authorities in Kerala, India, are currently on heightened alert following a significant rise in infections and fatalities associated with Naegleria fowleri, frequently referred to as the “brain-eating amoeba.” This year, Kerala has reported 69 cases of primary amoebic meningoencephalitis, which includes 19 deaths—a notable increase compared to the previous year when there were only 36 reported cases and nine fatalities.

The uptick in cases has drawn the attention of health officials, especially given that three deaths occurred in the past month, one of which was a three-month-old infant. The Naegleria fowleri amoeba is primarily found in warm waterways and typically infects individuals when contaminated water enters the nasal passages. Health Minister Veena George emphasized that, unlike the previous year, the current cases appear to be isolated incidents rather than linked to a specific water source, which has complicated ongoing investigations into the outbreak.

In response to the alarming trend, the Kerala government has initiated urgent measures to safeguard public health. These measures include chlorinating wells, water tanks, and bathing areas where the risk of infection is higher. The proactive approach demonstrates the state’s commitment to ensuring community safety and managing public health risks effectively.

While the overall number of cases remains relatively low, health officials have ramped up testing across Kerala in a bid to detect and treat infections promptly. Dr. Altaf Ali, part of the government’s task force addressing this health challenge, remarked that the emergence of new cases from different areas in the state, rather than concentrated pockets as seen in the past, adds complexity to their epidemiological efforts.

The U.S. Centers for Disease Control and Prevention has classified infections from Naegleria fowleri as “very rare but nearly always fatal.” The organism can lead to severe neurological symptoms, including headaches, fever, and vomiting, which can progress rapidly to seizures and altered mental states. As a point of awareness, it is important to note that since 1962, nearly 500 cases have been documented globally, predominantly in countries such as the United States, India, Pakistan, and Australia.

Kerala first documented cases of this rare infection in 2016, and this current health crisis underscores the importance of monitoring and addressing emerging health threats within communities. The state’s rigorous response to the Naegleria fowleri outbreak highlights its commitment to public health and safety, serving as a reminder of the collective responsibility to ensure hygiene and safety in natural water bodies.
