A review of civic measures undertaken ahead of the monsoon season to control mosquito-borne diseases such as dengue, malaria, and chikungunya has revealed that work on 6,160 water tanks belonging to 21 government institutions is still pending. Mosquito-borne diseases have become a perennial issue during Mumbai's rainy season, with the city's malaria problem worsening year after year.
Rising Malaria Cases
In 2025, Mumbai recorded 10,163 malaria cases, compared to 7,939 in the previous year, marking an increase of nearly 30%. This sharp rise highlights the urgent need for effective preventive measures. Meanwhile, dengue cases showed a decline, with 2,724 cases reported in the first nine months of 2025, down from 3,435 cases during the same period in 2024.
Civic Commissioner's Directives
During a review meeting held on Thursday, Municipal Commissioner Ashwini Bhide directed the civic insecticide department and related agencies to conduct a joint inspection campaign. She instructed that all necessary actions at vulnerable sites must be completed by May 31. Bhide emphasized that obstacles to the pest control department's access to dilapidated buildings, weed-covered areas, closed mill complexes, and restricted areas should be removed immediately.
The commissioner's directives come as part of a broader effort to mitigate the spread of mosquito-borne diseases, which have historically spiked during the monsoon season. The uncovered water tanks pose a significant risk as they can become breeding grounds for mosquitoes if not properly sealed or treated.
Call for Coordinated Action
The review meeting underscored the need for coordinated action among various civic departments and government institutions. The joint inspection campaign aims to identify and address all potential mosquito breeding sites across the city. Authorities have been urged to prioritize high-risk areas, including slums, construction sites, and neglected properties.
Residents are also being encouraged to take preventive measures, such as keeping water containers covered, clearing stagnant water, and using mosquito repellents. The civic body plans to intensify awareness campaigns and fogging operations in the coming weeks.
With the monsoon expected to arrive in Mumbai by early June, the civic administration is racing against time to ensure all preventive measures are in place. The completion of work on the remaining water tanks will be a critical step in reducing the burden of mosquito-borne diseases this season.
