The early onset of the monsoon has triggered a sharp spike in vector-borne diseases across Maharashtra, with the Pune-Mumbai belt witnessing a notable rise in malaria, dengue, and chikungunya cases. According to the state public health department, this year, over 7400 cases of these diseases have been reported by mid-June, although no deaths have been recorded so far.

Mumbai continues to top the urban chart, recording 2314 malaria cases, up from 1774 during the same period last year. It also reported 395 dengue cases and a dramatic surge in chikungunya infections from just 21 cases in 2024 to 119 cases this year till June 14.

In Pune, dengue cases in the district nearly doubled from 65 to 128, while chikungunya cases rose from 73 to 104. Malaria, which had been largely under control in Pune city last year, has made a return, with 13 cases already recorded in the Pune Municipal Corporation (PMC) limits, up from zero in 2024. Pimpri-Chinchwad also saw a slight uptick in malaria, from eight to 12 cases, and continues to report chikungunya activity.
