Residents across B.C.’s Interior are being urged by Interior Health (IH) to take precautions while tackling spring cleaning in dusty areas where rodents may be present. The Health Authority wants to spread awareness of the rare but serious hantavirus, an infection spread through contact with infected rodent droppings, urine or saliva.
In the region, the virus is most commonly carried by deer mice and can become airborne when contaminated dust is stirred up during activities like sweeping or dusting.
Health officials say cases are rare but can lead to hantavirus pulmonary syndrome, a severe illness that can affect otherwise healthy individuals. In the B.C. Interior, about one severe case is typically identified each year, though milder cases may go undiagnosed. Early symptoms can include fever, fatigue and muscle aches, with additional signs such as headaches, dizziness and nausea also possible.
IH is advising people to take steps to reduce exposure when cleaning enclosed or long-unused spaces. Recommendations include ventilating areas by opening windows and doors for at least 30 minutes, wearing proper protective gear such as N95 or higher-rated masks, gloves, eye protection and avoiding dry sweeping or vacuuming that can stir contaminants into the air. Instead, people are encouraged to use damp cloths or mops and to disinfect areas contaminated by rodent droppings using a bleach solution before cleaning. Proper disposal of contaminated materials and thorough handwashing are also recommended.
Interior Health says staying informed about public health guidance can help residents reduce their risk while completing seasonal cleaning tasks.
