Mosquitoes infected with West Nile virus detected in Yakima County

Mosquitoes carrying West Nile virus have been detected in Yakima County.

Samples were collected south of the Yakima River near Grandview, Benton County Mosquito Control said Thursday.

Officials said they have treated the area and will continue monitoring for the virus.

West Nile virus primarily affects mosquitoes and birds. It can, however, occur with humans and other animals.

Symptoms usually occur in three to 14 days after an infected mosquito bites a person.

Severe cases of the virus can cause inflammation of brain tissue and interfere with the central nervous system.

These symptoms are relatively rare. Only one in every 150 people who are infected will develop severe symptoms, according to the Benton County Mosquito Control website.

Milder symptoms include fever, headache, body aches, nausea and vomiting.

About 80 percent of people who do get infected won’t show any symptoms.
