Sri Lanka is experiencing a surge in dengue infections, with 2,671 active cases reported as of May 4, according to Dr. Kapila Kannangara, Acting Chairman of the National Dengue Control Unit (NDCU).
Speaking at a media briefing, Dr. Kannangara said 809 cases were recorded within the first four days of May alone, signalling a sharp rise. This follows 5,662 cases in April and 6,013 in March, indicating a steady upward trend in infections.
He noted that the highest number of cases has been reported from four provinces, with the Western Province accounting for around 51.78% of the total. Parts of the Southern Province and Sabaragamuwa Province have also been identified as high-risk areas.
Recent intermittent rains have contributed significantly to the spread of dengue by creating favourable breeding conditions for mosquitoes. Dr. Kannangara stressed that most breeding sites are man-made, caused by improperly discarded waste such as plastic containers, bottles, and coconut shells. High-risk locations include schools, places of religious worship, government institutions, and private premises.
He warned that the Aedes aegypti mosquito, which transmits dengue and chikungunya, can travel distances of 200 to 300 metres, placing even well-maintained households at risk due to nearby breeding sites.
So far this year, 13 dengue-related deaths have been reported, although the fatality rate remains relatively low at around 0.5%. However, delays in seeking medical treatment have contributed to some deaths. He urged the public to seek immediate medical attention if a fever persists beyond three days or if additional symptoms develop, noting that early diagnosis and timely treatment can prevent severe complications.
Dr. Kannangara also highlighted the economic impact of dengue, explaining that patients often require hospitalisation for five to six days or longer. This leads to loss of income for families while increasing the burden on the public healthcare system, as treatment costs are covered by the state.
Calling for urgent collective action, he stressed the need for local authorities, schools, and communities to strengthen waste management and public awareness. Sustained cooperation, he said, is essential to control the spread of dengue, particularly as rainy conditions are expected to continue across the country.
