The West Valley Mosquito and Vector Control District detected the presence of West Nile Virus in a collection of five mosquitoes trapped near Mountain Avenue and Satterfield Way in Chino on Aug. 18.

It is the first detection of West Nile Virus in the boundaries of the District this year, said community outreach coordinator Brian Reisinger

The District includes Chino, Chino Hills, Montclair, Ontario, Rancho Cucamonga, and Upland.

The virus was found in the native Southern House mosquito, not the aggressively biting Aedes aegypti and Aedes albopictus mosquitoes that are bothering residents.

West Nile Virus can be transmitted to people through the bite of an infected mosquito, he said.

Up to 20 percent of people who become infected will have symptoms that could include body aches, fever, headaches, nausea, and vomiting, according to the California West Nile Virus website.

Eighty percent of infected people develop no symptoms.
