Health officials are reminding residents about the risk of hantavirus this spring in areas potentially infested by rodents. People are most often exposed when cleaning up enclosed buildings (such as grain bins, sheds, barns, garages, trailers, cottages and homes) or farm equipment and vehicles after winter.
“You can get hantavirus by breathing in contaminated airborne particles from the droppings, urine and saliva of infected deer mice,” Saskatchewan’s Deputy Chief Medical Health Officer Dr. Denise Werker said. “Hantavirus can cause a rare, but often fatal lung illness known as hantavirus pulmonary syndrome.”
Symptoms usually start within one to six weeks of exposure and include fever, muscle aches, cough, headaches, nausea and vomiting. Some people develop severe symptoms that can be life threatening. Seek medical attention immediately if you have a cough, fever and shortness of breath.
To avoid exposure to hantavirus, be aware of mouse droppings and nesting materials and take the following precautions when cleaning infested areas:
Also, take steps to reduce rodent infestations:
- Ventilate the building by opening doors and windows for at least 30 minutes before cleaning;
- Use wet mopping methods and wear rubber or plastic gloves;
- Wear goggles and a well-fitting N-95 type filter mask when cleaning areas contaminated by droppings in a confined space;
- Dampen areas contaminated with rodent droppings with bleach disinfectant and remove droppings with a damp mop or cloth;
- Avoid using dry cleaning methods such as dusting, sweeping, vacuuming or air-hosing;
- Steam clean, shampoo or spray upholstered furniture with a detergent, disinfectant or a mixture of bleach and water; andWash clothes and bedding with detergent in hot water.
There have been 31 people with hantavirus pulmonary syndrome reported in Saskatchewan since 1994, 10 of whom died.
- Block openings that might allow rodents to enter a building;
- Store human and animal food, water and garbage in containers with tightly fitted lids; and
- Move woodpiles or other potential hiding places for mice away from your home.
