Leptospirosis Deaths Confirmed at Highest Rate in Mumbai 2025
In 2025, Mumbai saw a high rate of confirmed deaths from leptospirosis, with nearly 60% of suspected cases being confirmed.
Dengue and malaria also saw changes in their confirmation rates.
Health activists and BMC officials have different views on how deaths are classified.
The data shows that while the number of suspected deaths decreased, the proportion of confirmed deaths increased, highlighting the need for early diagnosis and treatment during the monsoon season.
Leptospirosis had the highest confirmation rate among suspected monsoon disease deaths in Mumbai in 2025, with 59.4% confirmed.
Dengue confirmation rate increased to 50% in 2025, up from 25% in 2024.
Malaria confirmation rate remained at 38.9% in both 2024 and 2025.
The number of suspected deaths for dengue and leptospirosis decreased in 2025, but the proportion of confirmed deaths increased.
Health activists claim that patients with underlying illnesses are often recorded as dying from those illnesses rather than the infectious disease.
