Sri Lanka Deploys Military Drones to Combat Record Dengue Outbreak
7/21/2026, 6:56:35 AM
Outbreak Overview and Military Response
Sri Lanka is confronting its worst dengue surge in nearly a decade, with 53 deaths and 76,044 confirmed infections recorded since the outbreak began in January 2026. The rapid rise is driven by a more virulent DENV-2 strain, which accounts for roughly 75 % of cases. In response, the government has mobilized the air force to fly drones that map stagnant rooftop pools created by recent monsoon rains, while police and military personnel inspect homes, schools and construction sites for breeding grounds. Health officials report that nearly 11,000 mosquito-breeding sites were cleared in July, and fines were imposed on more than 4,000 premises found harboring water collections. Hospitals have added beds and converted wards to accommodate an influx of over 18,000 patients in the first two weeks of July alone.
Background & Context
The outbreak follows Cyclone Ditwah, Sri Lanka’s worst natural disaster in November 2025, which damaged critical infrastructure and health facilities, with losses estimated at $1.4 billion by the World Bank. The nation’s health system, previously boasting four hospital beds per 1,000 people—higher than the global average of fewer than three—now faces severe strain. Dengue cases typically surge during the rainy season; officials expect a modest decline as monsoon rains weaken in August, but warn of a possible rise in November when the second monsoon arrives.
Official Statements & Responses
Acting director-general of the National Dengue Control Unit Kapila Kannangara said the patient load and case severity are both high. Consultant Lalindra Dias of Negombo District General Hospital noted that the surge was expected to plateau before easing in August, though the unusual virulence makes precise forecasts difficult. The health ministry indicated that a dengue vaccine is under consideration, despite expert cautions about limited efficacy against multiple circulating strains.
