Sri Lanka continues to grapple with a significant dengue outbreak, with over 95,000 cases reported this year and 72 deaths recorded, according to the National Dengue Control Unit.
The National Dengue Control Unit has identified 50 Medical Officer of Health areas across Sri Lanka as remaining in the high-risk category for dengue transmission. This designation reflects ongoing concerns about the spread of the virus in multiple regions of the country.
Yearly case figures have climbed considerably, with 95,174 dengue infections reported throughout 2026. The disease's intensity is evident in August alone, which saw 9,838 cases—representing a significant monthly burden. The Western Province has emerged as the primary affected region, accounting for 50,358 cases, nearly half the national total. Other provinces face substantial burdens as well: the Southern Province has recorded 13,854 cases, the Central Province 8,659, and Sabaragamuwa Province 7,825 cases.
At the district level, Gampaha has been the hardest hit, documenting 20,276 dengue cases—the highest among all districts. The human toll of the outbreak has also been significant, with 72 dengue-related deaths reported nationally so far this year.
These figures highlight the persistent challenge posed by dengue in Sri Lanka, with the concentration of high-risk areas and continued case increases suggesting the outbreak remains a major public health concern requiring sustained attention and intervention.
