    A recent study in the Palouse region of Washington and Idaho found that nearly 30% of rodents showed evidence of past Sin Nombre virus infection, with about 10% actively infected. This suggests the virus, which causes hantavirus pulmonary syndrome, may be more widespread in Pacific Northwest rodent populations than previously recognized. Fieldwork for the study was conducted in Whitman County, Washington, and Latah and Benewah counties in Idaho. Human infections remain rare, but the study highlights the importance of awareness.
