Sri Lanka reports spike in dengue in first days of 2026
Nearly 2200 cases reported
According to media reports, Sri Lanka has recorded 2,170 dengue cases (averaging 240 cases per day) across 41 Medical Officer of Health (MOH) divisions during the first nine days of 2026.
Health officials with the National Dengue Control Unit say the 41 divisions are in a "dengue high-risk situation".
Officials say this is the result of floodwaters left by Cyclone Ditwah in late November and early December 2025.
Community medical specialist of the National Dengue Control Unit, Dr. Prashila Samaraweera said health teams have intensified surveillance and mosquito-control operations in these 41 affected areas.
Health officials have identified mosquito breeding grounds mainly in schools, government institutions, places of worship, and abandoned buildings and lands.
Sri Lanka recorded 51,479 dengue cases in 2025.
