Dengue outbreak overwhelms Sri Lanka as cases surpass 44,000 amid post-cyclone conditions

Sri Lanka is experiencing a severe resurgence of dengue fever, with health authorities reporting more than 44,000 infections and at least 28 deaths since the beginning of the year. The rapid spread of the mosquito-borne disease is placing significant pressure on hospitals already strained by seasonal demands.

Officials attribute the surge to a combination of seasonal monsoon rains and environmental disruption caused by Cyclone Ditwah, which struck the island in late November. The storm left behind widespread debris and stagnant water, creating ideal breeding conditions for mosquitoes across urban and suburban areas.

Health data shows a sharp acceleration in infections in recent months, with reported cases nearly doubling between April and mid-June. Public health specialists warn that transmission levels remain high and could continue rising for several weeks before beginning to decline.

Medical authorities also highlight the role of rapid urban expansion and inadequate waste management in worsening the outbreak. Standing water in densely populated areas has increased mosquito density, further intensifying the spread of the virus.

With more cases recorded this year than at the same point in previous outbreaks, officials are urging communities to eliminate potential breeding sites and strengthen preventive measures as the country works to contain one of its most serious dengue waves in recent years.
