🚨 Road Drains Driving 70% of Dengue Risk, Study Reveals

A new research study by Priyantha Wickramarathna and Prof. S.P. Samarakoon reveals a major gap in Sri Lanka's dengue prevention, showing that national infrastructure, rather than household negligence, is the primary driver of the current crisis. • The Core Finding: Open and exposed roadside drainage systems account for 70% of the overall dengue transmission risk. In contrast, households, schools, and workplaces account for only about 30%. • The Policy Mismatch: While national authorities heavily focus inspection and enforcement efforts on domestic and institutional environments, the study urges an immediate shift toward maintaining, covering, and managing public roadside drains. • 2026 Outbreak Data: Sri Lanka is facing a severe outbreak with 63,835 reported cases and 42 deaths (provisional data as of early July 2026). This includes a sharp spike of 21,543 cases in June alone. • Regional Epicentre: The Western Province remains the hardest hit, with Colombo (12,968 cases) and Gampaha (12,929 cases) together accounting for over 40% of the national total. • Critical Health Warning: Medical experts highlight that the most dangerous phase of dengue is the "Danger Window" (Days 4–6) when the fever begins to drop. This is when severe complications like bleeding and shock are most likely to occur, requiring vigilant clinical monitoring.
