HERMISTON — Umatilla County officials detected West Nile virus in three samples collected along the south bank of the Cold Springs Reservoir, according to a press release from the West Umatilla Mosquito Control District.
Residents living in the area can expect an ultra low volume of insecticide spraying from trucks running after sunset when mosquitoes are most active.
People infected with West Nile experience mild flu-like symptoms such as fever, headache, body aches, and occasionally swollen lymph glands or a rash. More extreme cases can cause inflammation of the brain.
Horses are also susceptible to West Nile, although a vaccine is available.
