FOR IMMEDIATE RELEASE
Jackson County, Ore.—West Nile virus (WNv) has been detected in mosquitoes collected July 21st, 2026, near the Expo in Central Point marking the second time in two weeks that WNv-positive mosquitoes have been found in the county. July, August and September are considered peak months for WNv activity in our region. The mosquitoes were collected by the Jackson County Vector Control District (JCVCD) as part of a routine surveillance program and tested using reverse transcriptase polymerase chain reaction (RT-PCR).
Residents are advised to take basic precautions against mosquitoes since WNv is spread to humans through the bites of infected mosquitoes. People should consult their health care providers if they experience any flu-like symptoms, especially in people over 50 years of age with underlying conditions such as high blood pressure and diabetes. Health care providers can contact the Jackson County Health Department for information on WNv testing.
The virus also affects wildlife and domesticated and farm animals. Horse owners should get their horses vaccinated for WNv. Horses with neurologic disease should be examined by a veterinarian. WNv testing is available at Oregon State University.
JCVCD suggests these steps to protect against mosquitoes:
- Eliminate or treat sources of standing water around your home
- Avoid outdoor activities at dusk and dawn when mosquitoes are most active
- Use repellants containing DEET, oil of lemon/eucalyptus, or Picardin (always follow label directions)
- Wear long-sleeved shirts and pants when outdoors
- Ensure that screen doors and windows are in good condition and fit tightly
