Colombo, Jan 8: Sri Lanka’s health authorities have stepped up surveillance and preventive measures amid growing concerns of a dengue outbreak following widespread flooding caused by Cyclone Ditwah.
Officials say dengue infections have shown a noticeable upward trend compared to the same period last year, raising fears that stagnant floodwaters could accelerate mosquito breeding and trigger fresh outbreaks. Early January data indicate a worrying pace of new infections, with health officials reporting hundreds of cases within the first week alone.
The Western Province continues to record the highest number of dengue patients, while several other districts across the island have also reported elevated case numbers, according to the National Dengue Control Unit (NDCU).
In response, authorities have intensified mosquito control programmes, including fogging operations in temporary shelters and high-risk zones, stricter waste disposal measures, and closer monitoring of fever patients in flood-affected areas. Special attention is being paid to locations identified as major breeding grounds, such as schools, government offices, places of worship, and abandoned buildings and lands.
Medical experts have urged the public to remain vigilant and seek prompt medical advice if symptoms such as fever occur. Health officials warn that self-medication or delaying professional treatment could lead to serious complications, particularly if dengue is not detected early.
The Health Ministry has called on communities to cooperate with control measures and eliminate potential mosquito breeding sites around homes and public spaces as the country braces for the heightened risk in the weeks ahead.
