Dengue Fever in Sri Lanka: A Growing Concern for Schools and Public Health
Recent surveys conducted by Sri Lanka’s Ministry of Health reveal a worrying trend: dengue larvae have been detected in 40 percent of inspected schools. This finding, reported on February 14, 2026, underscores the escalating risk of dengue fever across the nation and highlights the urgent need for preventative measures, particularly within educational institutions.
The Rising Threat: 2025 Dengue Cases and Beyond
Sri Lanka recorded over 51,000 dengue cases in 2025, demonstrating the significant public health challenge the country faces. The presence of mosquito breeding sites in schools is particularly concerning, as it exposes a large and vulnerable population – students and staff – to the disease. Acting Director of the National Dengue Control Unit, Kapila Kannangara, emphasized the ongoing inspection and prevention campaigns aimed at reducing these breeding grounds.
Protecting Students During Examinations
Recognizing the immediate risk, health authorities are proactively fumigating examination centers hosting the General Certificate of Education (Ordinary Level) examinations. This targeted approach aims to safeguard students and staff during a critical period, minimizing disruption to their studies and well-being. This demonstrates a commitment to protecting vulnerable populations during peak transmission periods.
A Proactive Approach to Dengue Control
The National Dengue Control Unit (NDCU), established in 2005 following a major outbreak in 2004, serves as the central coordinating body for dengue prevention and control efforts in Sri Lanka. The NDCU works in collaboration with organizations like the Sri Lanka Red Cross Society (SLRCS) and the International Federation of Red Cross and Red Crescent Societies (IFRC) to implement comprehensive strategies.
The Simplified Early Action Protocol (sEAP)
A groundbreaking initiative launched in December 2025, the Simplified Early Action Protocol (sEAP) for Dengue Prevention, represents a shift towards proactive public health interventions. This two-year program, running from July 2025 to June 2027, focuses on five high-risk districts: Colombo, Gampaha, Kalutara, Jaffna, and Kandy. The sEAP aims to empower communities to take simple, everyday actions to control dengue.
Pro Tip: Regularly inspect your surroundings for stagnant water – even small amounts can grow breeding grounds for mosquitoes. Empty and clean flower vases, pet bowls, and any containers that collect rainwater.
Community Involvement: A Shared Responsibility
Health officials consistently urge communities to eliminate stagnant water and maintain clean surroundings. This underscores the fact that dengue control is not solely the responsibility of health authorities; it requires collective effort and sustained community participation. Dr. Kapila Kannangara has stressed that environmental cleanliness is a shared responsibility.
Future Trends and Challenges
The increasing detection of dengue larvae in schools suggests a potential for larger outbreaks if preventative measures are not intensified. Climate change and urbanization are likely to exacerbate the problem, creating more favorable conditions for mosquito breeding. Continued investment in surveillance, vector control, and public awareness campaigns will be crucial to mitigating the risk.
Did you know? The Aedes aegypti mosquito, the primary vector for dengue fever, can breed in very small amounts of water, such as a discarded bottle cap.
