Hantavirus risk in Kolkata

Hantavirus Prevention Guide for Kolkata

Risk Score: 57/100

What is Hantavirus?

Hantavirus is a viral infection spread through contact with infected rodents, their droppings, urine, or saliva. It can cause Hantavirus Pulmonary Syndrome, a severe respiratory illness. While rare in India, the risk exists, especially in urban areas with rodent infestations.

Local Risk Factors in Kolkata

Kolkata's old infrastructure, narrow lanes, and waste accumulation create ideal conditions for rodent breeding. The monsoon season worsens flooding and dampness, increasing rodent movement into homes and commercial areas. Poor waste management in some neighborhoods raises exposure risk.

Prevention Steps

1. Seal entry points: Inspect walls, doors, and windows for gaps and holes. Use steel wool or cement to block entry points where rodents might enter your home or workplace. Pay special attention to ground-level openings in older buildings.

2. Manage waste properly: Dispose of food waste in sealed bins. Avoid leaving garbage bags on streets overnight. Encourage your neighborhood association to coordinate regular waste collection, especially before and during monsoon season.

3. Clean safely: Never sweep or vacuum rodent droppings directly. Wet the area with a bleach solution (1 part bleach to 10 parts water), let it sit for 5 minutes, then wipe with paper towels. Wear gloves and a mask during cleanup.

4. Store food securely: Keep grains, rice, and other staples in metal or thick plastic containers with tight lids. Avoid storing food on floors or in open sacks, especially in ground-floor shops and warehouses.

5. Report infestations: Contact your local municipal corporation ward office if you notice persistent rodent activity in public drains or buildings. Collective action with neighbors is more effective than individual effort alone.

If you develop sudden fever, muscle aches, or breathing difficulties after possible rodent exposure, seek medical care immediately and mention your concerns to your doctor.
