A recent internal survey by the Kolkata Municipal Corporation (KMC), on Tuesday, found that nearly 44 per cent of the total number of wards in areas under the corporation's jurisdiction, which included Kolkata and added areas, are dengue-prone, officials said.
The total number of the wards under KMC stands at 144.
As per the internal survey, 68 wards of them are dengue-prone, an insider from the corporation claimed.
"The corporation mapped all the 144 wards under its jurisdiction to identify the dengue-prone pockets based on past figures on this count. The benchmark in the matter is that if 10 or more persons in a particular ward have been tested positive for dengue last year, that particular ward is identified as the hotspot," a KMC official said.
As per records, the number of people tested positive for dengue in the KMC area witnessed an impressive decline in 2024 to just 1,316 from the figure of 13,926 in 2023.
