If you're diving into spring cleaning over the long weekend, be aware of ! Transmitted by some rodents (deer mice in particular in the IH region, pictured), it's a potentially serious infection. There are different hantaviruses around the world, but in B.C. and North America, we see the Sin Nombre Virus. The Sin Nombre Virus cannot be transmitted from one person to another.
Risks can be highest when cleaning a shed, attic or cabin that has not been used in a while, or when working in areas where mice live, such as barns. 🧹
You can get infected with hantavirus when hantaviruses from old rodent droppings and urine are stirred up into the air and then inhaled.
How can hantavirus be prevented?
🔹 Ventilate: having good ventilation is key to reducing the number of airborne hantaviruses in small spaces.
🔹 Gear up: Wearing a mask—N100, P100, R100 or N95—will help filter out airborne particles including hantavirus. Rubber gloves will protect your hands, and goggles will protect your eyes. Make sure to wash your hands with soap and water after removing your gloves.
🔹Clean safely: avoid stirring up dust as much as possible by using a damp cloth or mop to clean dusty corners, rather than vacuuming or sweeping (which can put particles into the air).
🔹If you come across rodent droppings or nests, wet the area with a general-purpose disinfectant, household detergent, or a mixture of bleach and water (one part bleach to 10 parts water). Let the area soak for five minutes prior to cleaning with a damp cloth or paper towel.
🔹Make sure to throw out the paper towel in a sealed plastic garbage bag. Double bag the contents and place in the garbage, as appropriate to local bylaws.
🔹Stay up-to-date on any advisories or guidelines issued by IH or your local health authority.
