Steps taken by the KMC:

• Identifying the high risk area: Based on the data for last 3 years, 52 wards were identified as high risk areas

• Joint drive for source reduction: KMC with other government departments like water supply, building, drainage and solid waste management took weekly joint drives for the period of peak malaria transmission. It was effective in destroying the mosquito breeding sites

• Use of larvivorous fish: Efforts to destroy mosquito by using guppy fish were taken. To ensure availability, in house production of guppy fish was made in hatcheries

• Mosquito research laboratory: Trinamool after coming to power in 2010, did set up the first-of-its kind laboratory in eastern India. Facilities were made for entomologists to undertake research and multiple research papers from the Institute  were published in journals of international repute
