DENV-2 Responsible for 88% of Dengue Cases in Sri Lanka, Health Officials Warn

The National Dengue Control Unit (NDCU) says that approximately 88% of all dengue infections reported in Sri Lanka so far this year have been caused by the Dengue Virus Type 2 (DENV-2) strain.

Director of the National Dengue Control Unit, Dr. Kapila Kannangara, said the DENV-2 strain poses a greater public health risk because many people have lower immunity against it, increasing the likelihood of infection and severe illness.

According to the latest figures released by the NDCU, the total number of dengue cases in Sri Lanka has risen to 75,321.

Health officials also revealed that 19,943 cases have been reported during the first 18 days of July, highlighting the rapid spread of the mosquito-borne disease across the country.

The dengue-related death toll has increased to 53, raising concerns among health authorities as the outbreak continues.

162 MOH Divisions Identified as High-Risk Zones

The National Dengue Control Unit said 162 Medical Officer of Health (MOH) divisions across Sri Lanka continue to be classified as high-risk dengue areas, with intensified surveillance and mosquito control measures being carried out.

Health authorities have urged the public to eliminate mosquito breeding sites by removing stagnant water, keeping surroundings clean, and seeking immediate medical attention if symptoms such as high fever, severe headache, body aches, or persistent vomiting develop.

The Ministry of Health continues to conduct nationwide dengue prevention programmes, inspections, and public awareness campaigns to reduce the spread of the disease.
