Sri Lankan health authorities inspected more than 70,000 premises on the first day alone of the national drive, according to the Ministry of Health and Mass Media, targeting potential mosquito breeding sites across the island.
According to the Ministry of Health and Mass Media, Sri Lanka has recorded 36,168 dengue cases and 20 deaths so far in 2026, underlining the scale of the outbreak that prompted the national crackdown.
