# Sri Lanka turns to drones to fight mosquitoes as dengue surges

With dengue cases nearing 50,000 this year and hospitals filling up, Sri Lanka has deployed drones and military personnel to hunt down the hidden pools of water where disease-carrying mosquitoes breed — part of a growing global turn to aerial technology against a disease that now threatens half the world's population.

Sri Lanka is using drones to help fight mosquitoes as a dengue outbreak strains its hospitals, with cases approaching 50,000 in the first half of 2026.

## A surge testing the system

The island has recorded tens of thousands of dengue cases this year — around 47,500 by late June, with 29 deaths, according to figures tracked from the country's Epidemiology Unit — and hospitals were admitting more than 1,000 dengue patients a day, [Arab News reported via AFP](https://www.arabnews.com/node/2648225/world). Officials fear a repeat of 2017, when a dengue epidemic infected some 186,000 people and killed 440. The Western Province around Colombo accounts for roughly half of infections. "We don't want to have a situation like the one we faced in 2017," the head of the government's dengue unit, Kapila Kannangara, said.

## Eyes in the sky

The challenge is finding where the *Aedes* mosquito breeds. It needs only a tiny amount of standing water, and much of it collects out of sight — in clogged roof gutters, rooftop water tanks, discarded tires and concrete slabs that hold rainwater — places a ground inspector cannot easily see. Drones can. Surveying neighborhoods from above, they flag likely breeding sites for health teams to investigate and drain or treat. The approach builds on research in Sri Lanka itself: a project by Sweden's [KTH Royal Institute of Technology and the University of Colombo](https://www.digitalfutures.kth.se/project/fighting-dengue-fever-with-aerial-drones/) developed a two-stage protocol in which drones survey from height, then drop lower to confirm standing water and larvae before alerting authorities.

The drones are part of a wider mobilization ordered by President Anura Kumara Dissanayake, whose office said army, navy and air-force personnel would join health inspectors, councils and volunteers, and that laws would be enforced against those allowing mosquitoes to breed on their property, [AFP reported](https://www.manilatimes.net/2026/06/24/world/asia-oceania/sri-lanka-troops-to-battle-deadly-dengue-mosquitoes-as-cases-rise/2371211).

## Why dengue is rising

The drivers are clear enough. Sri Lanka's southwest monsoon brings heavy rains that pool in containers and poorly drained urban spaces, a changing climate is intensifying those rains, and rapid urbanization multiplies the surfaces where mosquitoes can breed. Dengue spreads when an infected *Aedes* mosquito bites a person — it does not pass directly between people — and ranges from fever, headache and joint pain to, in severe cases, internal bleeding that can be fatal. There is no specific cure; care is supportive.

## A growing global threat

Sri Lanka's crisis mirrors a worldwide trend. The [World Health Organization](https://www.who.int/news-room/fact-sheets/detail/dengue-and-severe-dengue) reports that 2024 was the worst year on record, with more than 14.6 million reported cases and over 12,000 deaths across more than 100 countries, and estimates 100 to 400 million infections a year — with about half the world's population now living where dengue can spread. The disease is also pushing into new areas: parts of southern Europe have recorded locally acquired cases in recent years.

Technology is no silver bullet — controlling dengue still depends on people covering tanks, clearing gutters and removing standing water. But as outbreaks intensify and cities grow more complex, drones give overstretched health teams a way to see the hidden reservoirs that keep the cycle going.
