Mumbai has witnessed a rise in malaria, chikungunya, and hepatitis cases between January and September 15 this year compared to the same period in 2024, according to the Brihanmumbai Municipal Corporation’s (BMC) Monsoon-Diseases report released on Tuesday.
The city reported 6,277 malaria cases so far in 2025, up from 5,182 last year. Hepatitis cases rose to 913 from 791, while chikungunya cases climbed to 542 from 366 in the same period. In contrast, dengue cases dropped to 2,724 from 3,435, leptospirosis cases declined to 558 from 628, and gastro cases fell to 5,989 from 6,599.
The civic body noted that while malaria and chikungunya cases rose overall this year, the numbers have shown a downward trend since August, mirroring patterns seen in 2024. No increase was observed in other waterborne diseases.
During the Ganesh Chaturthi festival, BMC’s health department conducted multiple public health awareness initiatives across city wards, including cleanliness drives in hospitals and maternity homes to curb mosquito breeding. Between August 1 and September 15, officials inspected 4,74,450 houses and collected 83,228 blood samples. Extensive advisories were also issued for the prevention of vector-borne diseases such as malaria, dengue, and chikungunya.
The BMC has urged citizens to avoid stagnant water in and around their homes, ensure proper disposal of items like old tires and water tanks that can collect water, and refrain from consuming uncovered street food. Residents have also been advised to wash hands frequently, avoid self-medication, and seek medical help promptly in case of fever.
