BOISE, Idaho (AP) — A southwestern Idaho woman has become the eighth person statewide this year to be diagnosed with West Nile Virus, a mosquito-borne illness that can cause health problems. The woman is from Ada County, but the Central District Health Department says she was likely infected to the north, in Valley County, where she spends her weekends.

Concerns about the outbreak this year have escalated. Ada County Weed and Pest Control conducted aerial spraying for mosquitoes last week. Kimberly Link, Program Manager for Communicable Disease Control at the district, says southwestern Idaho appears to be a hotspot for the disease.

Still, the outbreak pales in comparison to 2006. That's when Idaho led the nation with 996 reported cases and numerous deaths. Officials urge people to cover their skin and use mosquito repellant.
