Dengue Fever in Sri Lanka: A Growing Concern for Schools and Public Health
Recent data reveals a worrying trend in Sri Lanka: a significant rise in dengue mosquito larvae detected in schools. As of February 14, 2026, health officials report larvae present in 40 percent of inspected schools nationwide. This increase underscores the ongoing battle against dengue fever, a major public health challenge for the country.
The Rising Threat in Educational Institutions
The presence of dengue larvae in schools is particularly concerning, as it puts students and staff at increased risk during crucial periods like examinations. Currently, fumigation activities are underway at centers hosting the General Certificate of Education (Ordinary Level) exams to mitigate this risk. This proactive measure highlights the government’s commitment to protecting vulnerable populations.
The National Dengue Control Unit (NDCU) is leading inspection and prevention campaigns, focusing on eliminating breeding sites. Acting Director Kapila Kannangara emphasized the importance of these efforts, noting the continued need to limit the spread of the disease.
Sri Lanka’s Dengue Landscape: 2025 and Beyond
In 2025, Sri Lanka recorded over 51,000 dengue cases, demonstrating the scale of the problem. The situation prompted the launch of a groundbreaking early dengue response program in December 2025, aiming for a shift from reactive disaster response to proactive public health interventions. This initiative, a collaboration between the Sri Lanka Red Cross Society (SLRCS), the International Federation of Red Cross and Red Crescent Societies (IFRC) and the Ministry of Health (MoH), focuses on five high-risk districts: Colombo, Gampaha, Kalutara, Jaffna, and Kandy.
The program, running from July 2025 to June 2027, introduces a Simplified Early Action Protocol (sEAP) – the world’s first dengue-specific sEAP. The SLRCS, with its extensive volunteer network, is playing a key role in implementing timely preparedness and response measures.
Community Involvement: A Critical Component
Health officials consistently urge communities to take responsibility for eliminating stagnant water and maintaining clean surroundings. What we have is not solely the responsibility of authorities; individual and collective action are vital in curbing dengue transmission. Dr. Kapila Kannangara, Director of the NDCU, has stressed that environmental cleanliness is a shared responsibility.
Pro Tip: Regularly check your surroundings for potential mosquito breeding sites – flower pots, discarded tires, and even clogged gutters can develop into havens for larvae.
Future Trends and Proactive Measures
The launch of the sEAP signals a move towards anticipatory public health interventions. This approach, focusing on preparedness and early action, is likely to become increasingly significant as climate change and urbanization contribute to the spread of vector-borne diseases like dengue. Continued investment in surveillance, early warning systems, and community engagement will be crucial.
