WhatsApp groups are being operated in every ward to address complaints regarding mosquito breeding.
Coordination and Resources
The Public Health Department is organising inter-departmental coordination meetings to prevent mosquito-borne diseases such as Dengue, Malaria, and Chikungunya. A meeting of Malaria Supervisors was held on February 20 to discuss malaria eradication efforts, followed by a technical meeting of entomologists on February 26.
The release stated that the Public Health Department of the Municipal Corporation of Delhi possesses an ample stock of anti-mosquito and anti-larval agents such as MLO, Temephos granules, Bifenthrin, Diflubenzuron, etc., to combat mosquito breeding.
High Rainfall Impact and Citizen Advisory
The Public Health Department has appealed to citizens not to allow water to stagnate in their surroundings.
Mosquito-borne diseases spread primarily due to mosquito breeding in waterlogged areas.
According to the Public Health Department, 30 millimetres of rainfall was recorded in April this year, the highest amount of rainfall witnessed in the month of April over the last 18 years. In contrast, only 0.7 millimetres of rainfall was recorded in April 2025. The above-average rainfall in April 2026 occurred in short, intermittent spells and has created conditions highly conducive to mosquito breeding.
Municipal Corporation of Delhi appeals to citizens to contribute towards the campaign against mosquito-borne diseases and advises citizens to keep open water containers covered and ensure that water tanks are securely closed and drain & clean water coolers at least once a week. (ANI)
