# Mumbai Doctors Warn of Leptospirosis After Monsoon Rain Exposure

Mumbai doctors are increasingly concerned about leptospirosis, a bacterial infection linked to dirty rainwater. Symptoms can appear days after exposure, mimicking common viral illnesses, making early diagnosis critical.

## Key takeaways

- Leptospirosis, a bacterial infection from contaminated water, poses a growing risk in Mumbai during monsoon season.
- Symptoms may not appear for up to two weeks after exposure, often mistaken for common viral fevers.
- Untreated leptospirosis can cause severe organ damage and can be fatal.
- Civic authorities are increasing inspections and public health advisories to combat monsoon illnesses.

Mumbai physicians are alerting parents to the risk of leptospirosis, a bacterial illness that can be contracted through contact with water contaminated by infected animal urine, particularly during the monsoon season. A 10-year-old's experience of developing a fever and body aches weeks after wading through waterlogged streets highlights the delayed onset of symptoms, which can resemble common viral infections.

## What Happened

Children are particularly susceptible to leptospirosis due to their tendency to play in puddles or walk barefoot in rainwater. The illness is caused by bacteria entering the body through minor cuts, scratches, or mucous membranes like the eyes, nose, and mouth. Symptoms typically emerge two to 14 days after exposure, potentially up to 30 days later, making the connection to recent rainwater contact difficult to recall.

## Why It Matters

Leptospirosis can lead to severe complications if left untreated, affecting vital organs such as the kidneys and liver, and potentially causing meningitis or breathing difficulties. In severe cases, it can be life-threatening. The Brihanmumbai Municipal Corporation (BMC) reported that among suspected monsoon-related deaths reviewed in 2025, leptospirosis had the highest confirmation rate at 59.4%, exceeding that of malaria and dengue. Data from January to July 2026 indicates a rise in leptospirosis cases in Mumbai, alongside increases in malaria and dengue.

## Background

Dr. Amol Jaybhaye, a Consultant in Infectious Diseases at Narayana Health SRCC Children's Hospital, noted that Mumbai has already observed an increase in leptospirosis cases this year compared to previous periods. The city's civic authorities have intensified their focus on monsoon illnesses, with measures including increased inspections at construction sites and expanded fogging operations.

## Key Facts

- Leptospirosis is a bacterial infection contracted from water contaminated with infected animal urine.

- Symptoms typically appear 2 to 14 days after exposure, sometimes up to 30 days later.

- Common symptoms include fever, body ache, and headache, which can mimic viral infections.

- The infection can enter the body through small cuts, scratches, eyes, nose, or mouth.

- Untreated leptospirosis can damage kidneys, cause meningitis, affect the liver, and lead to breathing problems.

- In 2025, 59.4% of suspected leptospirosis deaths in Mumbai were confirmed after clinical review.

- Mumbai has seen more leptospirosis cases this year than in the same period previously.

- BMC advises individuals who have walked through stagnant rainwater or mud with cuts/scratches to consult a doctor.

- Preventive antibiotics may be recommended within 24 to 72 hours of contact.

## What Happens Next

Parents are advised to seek prompt medical attention if a child exposed to dirty rainwater develops persistent high fever, breathing difficulties, yellowing of the eyes or skin, or a significant decrease in urine output, as these may indicate organ involvement. The BMC's preventive measures aim to mitigate the spread of monsoon-related illnesses.
