The Brihanmumbai Municipal Corporation (BMC) released its monsoon health report on Tuesday, September 2. According to the report, there has been a sharp increase in insect-borne diseases in the city this year, with malaria and chikungunya patients seeing the highest increase.
The number of malaria patients has increased to 5,706 from January to August 2025. While it was 4,021 during the same period in 2024. The number of dengue patients has also increased from 1,979 to 2,319. While the number of chikungunya patients has doubled from 210 to 485.
Meanwhile, city doctors said that the incidence of insect-borne diseases will remain the same for the rest of the month due to the spread of unhygienic conditions after the heavy rains during the festive season.
In contrast, the number of leptospirosis cases has declined slightly, from 553 last year to 471 this year. The number of gastroenteritis cases has also declined from 6,133 to 5,774.
Similarly, the number of COVID-19 cases has also declined from 1,775 to 1,111. However, the number of hepatitis cases has increased from 662 to 810.
The civic body has urged citizens to clean stagnant water, use mosquito nets, maintain cleanliness and not ignore persistent fever.
To curb the spread, the BMC has intensified its 'Zero Mosquito Eradication Campaign'. This includes 3,284 housing societies, 264 schools and 545 buildings. As part of this campaign, the municipal corporation actively searches for and destroys potential breeding grounds for mosquito-borne diseases.
The monsoon report reads, "Due to the intermittent rains, citizens are advised to ensure that water does not stagnate in or around their homes and nearby buildings, as such conditions provide breeding grounds for mosquitoes."
"People are urged to avoid walking barefoot during heavy rains to reduce the risk of infection," the monsoon report further says.
