Dengue and Chikungunya Outbreak in Sri Lanka: A Growing Public Health Concern

Strategic Insights -

Sri Lanka is facing a severe public health emergency due to the widespread outbreak of dengue and the resurgence of the chikungunya virus. The country's tropical climate and rapid urbanisation have created an ideal environment for mosquito-borne diseases to thrive. According to Dr. Preshila Samaraweera, a consultant community physician at the National Dengue Control Unit (NDCU), the Western Province has reported the highest number of dengue cases, with 36,628 reported since the beginning of 2023. The disease has claimed 13 lives so far this year, with many more at risk of developing life-threatening complications.
