Hantavirus risk in Phnom Penh

Hantavirus Prevention Guide for Phnom Penh

Hantavirus is a serious respiratory disease spread through contact with infected rodents, their droppings, urine, or saliva. In rare cases, it can cause severe lung failure. While the risk in Phnom Penh is moderate at 53 out of 100, it’s worth taking simple precautions.

Local risk factors in Phnom Penh include:

• Markets and food stalls with stored grains or waste that attract rats.
• Homes or warehouses with poor sealing around doors, windows, and pipes.
• Flooded areas after heavy rains pushing rodents into houses.
• Informal settlements with limited waste management and close housing.

Actionable prevention steps:

1. Rodent-proof your home

   • Seal gaps larger than a pencil-width under doors, around pipes, and in walls.
   • Use metal or thick plastic covers on vents and drains.
   • Keep food in tightly closed containers, especially rice, grains, and pet food.

2. Safe cleaning of droppings and nests

   • Never sweep or vacuum dry droppings; this stirs up virus particles.
   • Wet areas with bleach solution (1 part bleach to 9 parts water), wait 5 minutes, then wipe up with paper towels.
   • Wear gloves and a mask if available.

3. Reduce rodent food sources

   • Store garbage in closed bins and remove it regularly.
   • Avoid leaving pet food outside overnight.
   • Clean up spilled food in kitchens and storage areas quickly.

4. Improve ventilation and lighting

   • Open windows when possible to reduce stale air in storage rooms.
   • Use bright lighting in storage areas; rats prefer dark spaces.

5. Seek medical help early

   • If you develop sudden fever, muscle aches, and breathing problems after possible rodent exposure, see a doctor promptly.
   • Mention any known contact with rodents or droppings.

By keeping homes clean, sealed, and rodent-free, you can significantly lower your hantavirus risk in Phnom Penh.
