How do you prevent hantavirus?

Hantavirus prevention is straightforward but has to be done correctly: dry sweeping aerosolizes virus particles and is a recognized exposure route. The CDC and ECDC guidance converges on the same playbook. Seal cracks and gaps in homes, sheds, and outbuildings — pencil-sized openings are enough for a deer mouse. Eliminate food sources by storing food and pet food in rodent-proof containers and removing trash and brush near structures. When cleaning droppings or nests, ventilate the space for 30 minutes, wear rubber or latex gloves, wear an N95 or higher respirator, wet down the area with disinfectant (1:10 household bleach is standard) and let it sit for 5 minutes before wiping. Bag and discard waste in sealed plastic. After cleaning, wash hands thoroughly. Camping and cabin owners should pay special attention to spaces opened after winter dormancy, when rodent activity is high. No licensed vaccine is available outside of Korea and China.
