State and local public health officials are reporting the season’s first West Nile virus (WNV) detections in positive mosquito samples in Dawson and Lewis and Clark counties.  

The first horse infected with WNV this season was also confirmed earlier this week in Lewis and Clark County. The great news is, to date, no human cases of WNV have been identified this season.

Increased risk of WNV infection in humans and horses is expected to continue through at least October.

The detection of WNV in mosquitoes and horses is an early warning that Montanans are at an increased risk of infection.
