*MOSQUITO SAMPLES reflect results from counties that are part of a sampling effort. In these areas, single samples of up to 50 mosquitoes were tested for WNV.
CAUTION - Counties not identified with WNV may still have the virus present despite the lack of positive test results . It should be presumed that the virus can be found anyplace in Montana and all residents should follow the recommended precautions.
