Sri Lanka’s dengue death toll has risen to 53 this year, with more than 75,000 cases reported so far, as health authorities warn that school premises are turning up as the single most common mosquito breeding site during inspections.

The National Dengue Control Unit (NDCU) says dengue larvae have been detected most frequently on school grounds this year, with breeding also identified at factories, government institutions and other public places, according to NewsFirst. Acting Director Dr. Kapila Kannangara said the Western Province accounts for 52.7% of all cases nationwide.

The unit highlighted a striking pattern in fatalities: about 70% of dengue deaths — 37 of the total — have been among women. Officials urged women in particular to seek medical attention as soon as symptoms appear, noting that many deaths occurred because patients sought treatment too late. Most fatalities have been among those aged 25 to 49 and those over 65, while five children are also among the dead.

Sri Lanka Police have separately urged the public to act immediately to eliminate breeding sites, warning that strict legal action will be taken against those who maintain premises that allow mosquitoes to breed, Ada Derana reported.

Dengue, spread by the Aedes mosquito, typically surges during and after rainfall when discarded containers, blocked drains and construction sites collect stagnant water. Authorities have repeatedly called on households, schools and workplaces to inspect and clear potential breeding grounds each week.
