Virus-Carrying Mosquitoes Overwhelm Mumbai

Mumbai, the capital city of the Indian state of Maharashtra, with a population of over 12 million residents, recently reported a significant increase in vector-borne diseases in 2025.

As of September 2025, the Brihanmumbai Municipal Corporation's (BMC) health report reveals a surge in cases of chikungunya, dengue, and malaria, which are impacting Mumbai's residents, formerly known as Bombay.

Daijiworld Media reported BMC data shows Mumbai has confirmed 5,706 malaria cases, a 42% rise compared to 2024.

Chikungunya cases increased from 210 in 2024 to 485 this year.

Dengue cases increased from approximately 1,979 to 2,319 in 2025.

To contain the spread, the BMC has restarted its 'Zero Mosquito Breeding' initiative to reduce the number of virus-carrying vectors.

BMC officials said cases are expected to decline once monsoon activity eases.

To alert international visitors, both the U.S. CDC and the UK government have issued travel vaccine advice for those planning trips to Maharashtra in 2025. Mumbai attracts almost 6 million tourists annually.

The CDC recommends that chikungunya vaccination may be considered for individuals traveling to or residing in this location for an extended period (e.g., 6 months or more).
