Sri Lanka has recorded over 80,000 dengue cases and 59 deaths in 2026, a 30% jump over last year. Western Province accounts for half the cases; drones are being used to spot breeding sites.
Sri Lanka Dengue Crisis: 80,000 Cases, 59 Deaths
Sri Lanka's hospitals are stretched thin. Over 80,000 dengue cases and 59 deaths this year, up 30% on last year — and July alone has been the worst month of the outbreak.
Sri Lanka is in the grip of its worst dengue outbreak in a decade. The country has recorded more than 80,000 infections and 59 deaths so far in 2026, with hospitals pushed to their limits.
The Numbers
As of late July, cases stood above 80,000 — roughly 30% higher than the same period last year. July alone accounted for nearly 24,739 cases, making it the worst month of the outbreak, with an average of about 2,391 new cases reported daily.
Where It Is Worst
Western Province accounts for roughly half of all reported cases. Gampaha has reported around 16,950 infections and Colombo about 16,091, with Kalutara also heavily affected. Health authorities have flagged 175 high-risk MOH areas.
What's Driving It
Heavy rainfall and flooding from the southwest monsoon have created ideal mosquito breeding conditions — standing water in construction sites, roof gutters, discarded containers and blocked drains.
