Health officials in Eastern Oregon's Malheur County say they have discovered mosquitoes carrying the West Nile Virus. The Ontario Argus Observer reports that the mosquitoes were caught in traps in the Harper/Little Valley Area and were the first to test positive for West Nile in Oregon this year.
10 Idaho counties found evidence of the West Nile Virus in 2012, with human cases reported in Elmore, Gem, Payette, Twin Falls and Washington counties. Additionally, horses in Canyon, Gooding, Owyhee and Washington counties tested positive for West Nile in 2012.
Symptoms include fever, headache, nausea, vomiting and swollen lymph nodes.
The Department of Health and Welfare urge residents to reduce the chances of infection by applying mosquito repellant containing DEET, Picaridin or Lemon Eucalyptus, and cover up exposed skin when outdoors.
