A Public Health Agency of Canada (PHAC) expert is urging Canadians to take precautions against hantavirus when opening cottages, sheds, and other buildings that have been closed for the winter. The advice comes amid a hantavirus outbreak linked to a cruise ship that has resulted in two deaths and several infections.
Understanding the Risk
Hantavirus is a rare but serious disease transmitted through contact with infected rodents, particularly deer mice. The virus can cause hantavirus pulmonary syndrome (HPS), which can be fatal. According to PHAC, the risk of infection increases when entering spaces that have been undisturbed for long periods, as rodents may have nested there.
Precautions to Take
Dr. Theresa Tam, Canada's Chief Public Health Officer, recommends the following steps when reopening seasonal properties:
- Air out the building for at least 30 minutes before entering. Open doors and windows to allow fresh air to circulate.
- Wear protective gear, including gloves, goggles, and a mask (N95 or higher) to avoid inhaling dust particles.
- Avoid sweeping or vacuuming initially, as this can stir up dust. Instead, wet down surfaces with a disinfectant solution (1 part bleach to 9 parts water) before cleaning.
- Seal any holes where rodents could enter, using steel wool or caulking.
Context of the Outbreak
The warnings come after a hantavirus outbreak on the cruise ship Saint Helena, where 29 passengers disembarked and two later died. Health officials are monitoring dozens of individuals who may have been exposed. The World Health Organization has deemed the public health risk as low, but the situation has caused concern among travelers and the public.
What to Do If You Suspect Exposure
If you experience symptoms such as fever, muscle aches, fatigue, or difficulty breathing within 1 to 8 weeks of potential exposure, seek medical attention immediately. Early detection is critical for managing the disease. PHAC advises informing your healthcare provider about any possible contact with rodents or their droppings.
While the overall risk remains low, taking these simple precautions can significantly reduce the chance of infection. As Canadians prepare to open their seasonal properties this spring, following these guidelines is essential for safety.
