The Municipal Corporation of Delhi’s (MCD’s) anti-mosquito operations data show intensified preventive efforts this season. Between January 1 and August 23 this year, officials carried out over 2.67 crore household inspections for mosquito breeding — the highest in three years.
Of these, 1.37 lakh houses were found positive for breeding. Nearly 98,976 legal notices were issued and 18,795 prosecutions launched for violations.
During the same period, 8.79 lakh houses were sprayed, while the MCD also carried out 4,588 general body drives, collecting penalties amounting to Rs 13.89 lakh. For biological control, fish were introduced in 304 water bodies, up from 209 last year.
Officials noted that while dengue cases remain comparatively low, the rising trend in malaria and chikungunya infections calls for continued vigilance. With September approaching — the peak season for vector-borne diseases in Delhi — residents have been urged to maintain dry surroundings and cooperate with civic mosquito-control measures.
