Dengue cases on the rise: Dengue Control Unit

Colombo, May 6 (Daily Mirror) - Sri Lanka is witnessing 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 increase. This follows 5,662 cases in April and 6,013 in March, indicating a steady upward trend.

He noted that the highest concentration of cases has been reported in four provinces, with the Western Province accounting for approximately 51.78% of the total. Parts of the Southern and Sabaragamuwa provinces have also been identified as high-risk areas.

Recent intermittent rains have significantly contributed 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, coconut shells and other debris. High-risk locations include schools, places of religious worship and government institutions, followed by private premises.

He warned that the Aedes aegypti mosquito, which transmits both 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. Dr. Kannangara urged the public to seek immediate medical attention if fever persists beyond three days or if additional symptoms develop, emphasising that early diagnosis and timely treatment can prevent severe complications.

He also highlighted the broader economic impact of dengue, noting that patients often require hospitalisation for five to six days or longer. This results in loss of income for families while increasing the financial burden on the public healthcare system, as treatment costs are borne 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.
