The highest number of cases (22,186) was reported from the Colombo District while the second highest (17,228) from the Gampaha District. Of the rest of the districts the number of dengue cases was as follows: Kalutara (5,616), Kandy (6,017), Batticlaoa (4,155), Trincomalee (4,428), Kurunegala (6,014), Ratnapura (6,081) and Kegalle (4,949).

Dr. Samaraweera said environmental management was a prerequisite for controlling dengue. The management included environmental modification, environmental manipulation, and strategies that reduced contacts between vectors and humans.
In the case of mosquitoes, the larvae were easier to control than adults because they were confined to water, she said. Therefore, the “source reduction” should be a primary consideration in mosquito control.
