Mumbai has reported a significant rise in malaria and chikungunya cases this year. According to the Brihanmumbai Municipal Corporation (BMC), 4,825 cases of malaria were recorded between January and August 2025. The number was 4,021 during the same period in 2024.
This means there was a 20% increase in malaria this year. Health officials have linked the rise to the early arrival of the monsoon in May. The rains created breeding grounds for mosquitoes, leading to more vector-borne diseases.The latest report from the BMC Health Department shows the following trend:
Disease | Cases in 2024 | Cases in 2025 | Change (%) |
Malaria | 4,021 | 4,825 | 20% |
Chikungunya | 210 | 328 | 56% |
Dengue | 1,979 | 1,564 | -21% |
Gastroenteritis | 6,133 | 5,510 | -10% |
Leptospirosis | 553 | 316 | -43% |
Hepatitis | 662 | 703 | 16% |

Campaigns were carried out at 18 hospitals for anti-vector measures. Around 1,321 private doctors were sensitised to improve diagnosis, reporting, and treatment of vector-borne illnesses.
