Colombo, May 13 Sri Lanka has recorded 27,754 dengue cases and 14 deaths so far this year, with infections reported from all 25 districts, health officials said.
The National Dengue Control Unit said the number of confirmed cases has increased compared with 2025. The highest number of infections has been reported from the Western Province, while Matara, Galle, Ratnapura, Kalutara and Kandy have also recorded significant case numbers during the first four months of 2026.
Community Medical Specialist Priscilla Samaraweera of the National Dengue Control Unit said at a media briefing held at the health ministry that the start of monsoon rains could further increase transmission.
Officials said breeding has increased more in schools, workplaces, religious institutions and government and private institutions than in households. Improper waste disposal was identified as a key factor contributing to the spread of dengue, emphasizing the need for strict public cooperation in prevention, Xinhua news agency reported.
The public has also been advised to seek medical attention without delay if fever is accompanied by at least two symptoms such as muscle pain, headache, vomiting, nausea or skin rashes.
Dengue (break-bone fever) is a viral infection that is spread from mosquitoes to people. It is more common in tropical and subtropical than in temperate climates.
Most people who get dengue do not have symptoms. For those who do, the most common symptoms are high fever, headache, body aches, nausea and rash. Most get better in 1–2 weeks. Some develop severe dengue and need care in a hospital.
In severe cases, dengue can be fatal.
You can lower your risk of dengue by avoiding mosquito bites, especially during the day.
Dengue is treated through pain management as there is no specific treatment currently.
Individuals who are infected for the second time are at greater risk of severe dengue. The symptoms of severe dengue often come after the fever has gone away and may include: severe abdominal pain, persistent vomiting, rapid breathing, bleeding gums or nose, and fatigue.
The incidence of dengue has grown dramatically worldwide in recent decades, with the number of cases reported to WHO increasing from 505 430 cases in 2000 to 14.6 million in 2024. The vast majority of cases are asymptomatic or mild and self-managed, and hence the actual numbers of dengue cases are under-reported. The disease is now endemic in more than 100 countries.
In 2024, more cases of dengue were recorded than ever before in a 12-month period, affecting over 100 countries on all continents. During 2024, ongoing transmission, combined with an unexpected spike in dengue cases, resulted in a historic high of over 14.6 million cases and more than 12 000 dengue-related deaths reported. The Region of the Americas contributed a significant proportion of the global burden, with over 13 million cases reported to WHO.
