Kolkata’s New Directive Clean Water in Flower Stalls

In a proactive move to curb the spread of dengue fever, the Kolkata Municipal Corporation (KMC) has issued a directive urging flower vendors to ensure the cleanliness of water containers used for storing tuberose sticks. This initiative is part of a broader strategy to combat mosquito breeding grounds, specifically targeting areas where stagnant water could potentially foster the Aedes Aegypti mosquito, a primary vector for dengue fever.

The Ex-Officio Chief Vector Control Officer at KMC highlighted this precaution in a recent social media video, stressing the need for heightened vigilance during the monsoon months of September and October. The advisory underscores the importance of regular cleaning and maintenance of water storage areas, as these can inadvertently become breeding sites for disease-carrying mosquitoes if left unchecked. In light of these measures, KMC has noted a significant reduction in dengue cases this year. As of September 1, 2024, reported dengue cases in West Bengal have decreased by 83 per cent compared to the same period in 2023, with 333 cases this year versus 1136 last year. Similarly, malaria cases have dropped by 33 per cent, from 4546 in 2023 to 2169 in 2024.

The Chief Vector Control Officer also emphasised the effectiveness of using hand mikes for public awareness campaigns. He advised that announcements should be tailored to specific locations—different messages are needed for high-rise buildings compared to market areas. For high-rises, the focus should be on preventing stagnant water on rooftops and ensuring rainwater pipes are regularly cleaned. Flower vases, in particular, should have their water changed weekly to avoid becoming mosquito breeding sites. KMC is actively monitoring dengue reports from private hospitals and laboratories, prioritising interventions in areas identified as breeding grounds for Aedes mosquitoes. The corporation’s approach highlights the critical need for collaborative efforts between municipal authorities and the public to manage and mitigate vector-borne diseases effectively.
