Hantavirus Awareness

April 2019

Hantavirus is a virus that is found in the urine, saliva, or droppings of infected deer mice and some other wild rodents. It causes a rare but serious lung disease called Hantavirus Pulmonary Syndrome (HPS).

People can become infected with a hantavirus when they:

  • inhale virus particles from rodent urine, droppings or saliva that have been released into the air, this can happen when rodent waste is stirred up from vacuuming, dusting or sweeping.
  • touch objects or eat food contaminated with the urine, droppings or saliva of infected rodents
  • are bitten by a rodent infected with a hantavirus (this is rare)


There are a number of ways you can help to prevent a hantavirus infection:

     1. prevent rodent infestations

    • block openings that might let rodents in
    • store food, water and garbage in containers with tightly fitted lids
    • place mousetraps throughout buildings
    • keep your yard clean
    • stack woodpiles away from buildings

     2. Properly clean and disinfect areas contaminated by rodent droppings.

    • Wear rubber or plastic gloves. If you are cleaning in a confined space, wear a high-efficiency particulate air (HEPA) filtered respirator.
    • Do not sweep or vacuum rodent droppings. This will release particles into the air, which you could then breathe in.
    • Spray droppings with a household disinfectant or a mixture of 1 part bleach to 9 parts water. Let the area soak for 10 minutes to make sure any virus within the droppings will be killed.
    • Wipe up wet droppings with paper towels or a wet mop if dealing with a large area.
    • Wash gloves in disinfectant and hot soapy water before taking them off. Afterwards, wash your hands thoroughly.
    • If a wet mop was used to clean the area, use disinfectant and hot soapy water to clean the mop.
