West Nile Virus Still Persists Among Mosquitoes in Morrow County


West Nile virus has been detected in six additional mosquito pools captured the nights of Sept. 13-14 from various testing sites in the rural areas of Boardman and Irrigon, according to Oregon State University’s Veterinary Diagnostic Laboratory.

The North Morrow Vector Control District is advising people in Morrow County to take precautions against mosquitoes to avoid the risk of infection, including preventing mosquito bites. West Nile virus is spread to humans through the bite of an infected mosquito.

People should consult their health care providers if they have these symptoms. Health care providers can contact the Morrow County Health Department for information on West Nile virus testing.

Greg Barron, manager of the vector control district, says people should take precautions to avoid mosquito bites, including:

  • Eliminate sources of standing water that are a breeding ground for mosquitoes, including watering troughs, bird baths, ornamental ponds, buckets, wading and swimming pools not in use, and old tires.
  • When engaged in outdoor activities at dusk and dawn when mosquitoes are most active, protect yourself by using mosquito repellants containing DEET, oil of lemon eucalyptus or Picardin, and follow the directions on the container.
  • Wear long-sleeved shirts and long pants in mosquito-infested areas.
  • Make sure screen doors and windows are in good repair and fit tightly.
