A Washington State University (WSU) study revealed that the Sin Nombre virus, a type of hantavirus, may be more widespread among rodent populations in parts of the Pacific Northwest. The study found that nearly 30% of rodents in the Palouse region of Idaho and Washington showed signs of past infection, with 10% actively infected. Deer mice, voles, and chipmunks are vectors, and activities disturbing rodent nests increase exposure risk.
