Sri Lanka has recorded 61,060 dengue fever cases so far this year, with 2,604 new infections confirmed within a single 24-hour window, according to data from the National Dengue Control Unit (NDCU). The Western Province remains the center of the outbreak, housing 52.5 percent of the national case load and placing significant strain on regional healthcare capacity.
Where are dengue infection rates highest?
The Western Province remains the primary hotspot for the virus, accounting for 32,054 of the 61,060 total cases reported nationwide. Following the Western Province, the Southern Province has identified 9,674 cases. Other regions reporting significant infection numbers include Sabaragamuwa with 5,237, the Central Province with 4,823, the Eastern Province with 2,979, and the North Western Province with 2,778.
The NDCU has officially designated 142 Medical Officer of Health (MOH) divisions across Sri Lanka as high-risk zones.
How is the current outbreak impacting hospitals?
Several hospitals located within the Western Province have reached maximum capacity due to the surge in patients. Acting Director of the NDCU, Dr. Kapila Kannangara, stated that the rise in infections has placed severe pressure on hospitals and made patient care increasingly difficult.

The scale of the outbreak is visible in the monthly data. June recorded the highest monthly case total so far this year, with 21,546 infections. This trend has forced health authorities to pivot their operational focus toward emergency interventions to prevent a potential rise in fatalities.
What is the official response strategy?
To manage the ongoing public health crisis, the NDCU has implemented a three-phase strategy. Dr. Kannangara noted that this plan encompasses short-term, medium-term, and long-term measures. Currently, authorities are prioritizing the short-term interventions to alleviate the immediate strain on hospital resources and stabilize patient intake.
Pro Tips for Dengue Prevention
