Leptospirosis During the Rains: What You Should Know

The monsoon season brings much-needed relief from summer heat — but it also increases the risk of certain infections, one of the most concerning being leptospirosis. Often called “rat fever,” leptospirosis is a bacterial infection that becomes more common during heavy rains and floods.

What is Leptospirosis?

Leptospirosis is caused by Leptospira bacteria, typically found in the urine of infected animals, especially rodents. During rains, this contaminated urine mixes with floodwater or stagnant water in streets, fields, and open drains. Humans can become infected through cuts or abrasions on the skin or by contact with mucous membranes (eyes, nose, mouth) when exposed to contaminated water.

Common Symptoms

Symptoms of leptospirosis often mimic other illnesses and can range from mild to severe:

•High fever with chills

•Muscle pain, especially in the calves and lower back

•Headache

•Redness in eyes

•Nausea, vomiting

•Jaundice (yellowing of skin or eyes)

•In severe cases: kidney damage, liver failure, or meningitis

Who Is At Risk?

•People wading through floodwaters

•Sanitation workers and sewage cleaners

•Farmers and outdoor laborers

•Pet owners and individuals handling animals

•Children playing in puddles or contaminated water

Prevention Tips

•Avoid walking through floodwater when possible. Use waterproof boots if necessary.

•Cover any wounds or cuts with waterproof dressings.

•Maintain personal hygiene – wash feet and hands with soap after exposure to water.

•Keep rodents away – ensure your home and surroundings are clean and garbage is disposed of properly.

•If advised by your doctor, doxycycline prophylaxis may be considered for high-risk individuals.

When to See a Doctor

If you experience fever, body ache, or other flu-like symptoms after exposure to flood or dirty water, consult a doctor immediately. Leptospirosis is treatable with antibiotics if diagnosed early. Delayed treatment can lead to serious complications affecting the kidneys, liver, or brain.

Final Word

Leptospirosis is preventable — awareness and caution are your best shields. This monsoon, stay safe, stay dry, and prioritize hygiene to protect yourself and your family from this seasonal threat.
