A third Idaho county is reporting the discovery of West Nile virus in a mosquito, found west of downtown Payette.
Payette County joins Ada and Canyon counties, which have already reported the virus this year. Health officials say no human cases of West Nile have been confirmed yet, but urge the public to use mosquito repellent containing DEET, Picaridin or Lemon Eucalyptus, drain all sources of standing water, and avoid outdoor activity in dawn and dusk hours where mosquitoes are prevalent.
Locally acquired mosquito-borne human infections were first recorded in Idaho in 2004. In 2006, Idaho led the nation in reports of human illness associated with WNV, with 996 cases being reported to the state health department.
The virus can cause serious illness in people of any age, but especially in people over the age of 50 or those with underlying medical conditions.
