# Drones Used to Fight Mosquitoes as Dengue Fever Surges in Sri Lanka

> **Open Intelligence Dossier** · First detected: 2026-06-28 10:07 UTC · Category: Health

## Executive Summary
Sri Lanka implements drone technology for mosquito control as dengue fever cases surpass 53,000 this year.

## Intelligence Brief
Sri Lanka is deploying drones to combat mosquito populations amid a surge in dengue fever cases. The National Dengue Control Unit has identified prolonged rainfall and the DENV-2 virus as factors driving the current outbreak. Reported cases for 2026 have exceeded 53,000, though public health inspectors have indicated that actual figures may be significantly higher.


Coverage from The New York Times, Newsfirst, and the Daily Mirror highlights a divide between government measures and expert recommendations. While authorities are utilizing drones and preparing new circulars to strengthen control, entomologists and health experts are questioning the effectiveness of fogging. Reports note that fogging may harm beneficial insects like bees and dragonflies, and health experts have explicitly challenged recent claims by the Prime Minister regarding the emergence of a new virus strain.


Future developments will involve a military-led monitoring unit tasked with oversight as the country continues to identify risk zones, including the Kandy District and Matara. It remains to be seen how the government will reconcile the push for intensified control measures with expert warnings regarding long-term, sustainable solutions to the outbreak.
