HERMISTON, Ore. (AP) - Health officials say West Nile virus has been found in Umatilla County for the first time this year.
The West Umatilla Mosquito Control District on Thursday said mosquitoes trapped in Hermiston tested positive for the virus.
The district said confirmation testing will take place later this week at the Oregon State University Veterinary Diagnostic Laboratory.
Applications of insecticides from truck mounted sprayers will be used to reduce mosquito populations. These applications will typically happen after sunset, when mosquitoes are most active.
The West Nile virus is transmitted to humans and animals by the bite of an infected mosquito. Some people who become infected may develop mild flu-like symptoms. In rare cases, the virus may cause severe neurological issues. Older people have a higher chance of getting sick.
