West Nile Virus Found in Eagle Point Mosquito Trap During Routine Testing

JACKSON COUNTY, Ore. — A mosquito pool at Eagles Point in Jackson County has tested positive for West Nile virus for the first time in 2026

West Nile Virus Identified In Eagle Point Trap

After the West Nile virus (WNv) was been detected in a mosquito pool from a sample collected as part of a routine surveillance program and DNA testingJuly 15 in Eagle Point, the Oregon Health Authority (OHA) warmed the public to protect themselves against mosquitoes. The insects can spread West Nile to people.

Mosquito pools are traps that hold up to 50 insects that county vector control districts use to collect mosquitoes so they can be tested for mosquito-borne diseases that affect humans and animals, such as birds and horses.

West Nile virus appears annually in Oregon, and the virus was found in:

• 2023: in 70 mosquito pools, four horses and 17 people.
• 2024: 21 West Nile-positive mosquito pools, but no human or animal infections.
• 2025: 11 mosquito pools, two horses and two people- both of the human infections were acquired outside Oregon.

OHA warned Oregonians to use insect repellents, eliminate standing water where mosquitoes can breed, and wear long-sleeved shirts and pants when outdoors. Horse owners should get their horses vaccinated for WNv, but horses with neurologic disease should be examined by a veterinarian. WNv testing is available at Oregon State University.

More information about West Nile virus is available from the OHA website and the U.S. Centers for Disease Control and Prevention.
