Bengaluru has witnessed an extraordinary 90% decline in dengue cases this July — a period typically marked by a spike in infections. According to data from the Bruhat Bengaluru Mahanagara Palike (BBMP), the city reported just 518 cases in July 2025, compared to over 5,000 during the same month last year.
Throughout 2025 so far, only 1,761 cases have been recorded — a sharp contrast to the 15,282 infections logged in the first seven months of 2024. Experts credit this drop to proactive public health strategies and climatic conditions less favourable to mosquito breeding.
BBMP officials launched early mosquito-control drives, anticipating a possible resurgence due to the previous year’s surge. Additionally, sporadic rains and slightly higher temperatures disrupted optimal conditions for mosquito reproduction. These timely interventions significantly limited disease spread.
The Karnataka health department also stepped up by launching door-to-door awareness and inspection campaigns ahead of the monsoon. Around 700 volunteers and 240 inspectors canvassed the city, identifying and eliminating breeding grounds. Over 1,300 schools also joined the effort, training 21,000 students and 15,000 teachers in mosquito prevention techniques.
Despite overall improvements, certain zones like Mahadevapura (209 cases), Bengaluru East (109), and Bengaluru South (82) remain hotspots. These areas, with ongoing construction and water stagnation, pose elevated risk.
To tighten control, BBMP has imposed fines: ₹4,000 on construction sites, ₹2,000 on commercial establishments, and ₹800 on households that allow breeding.
