BOARDMAN – The North Morrow Vector Control District reports it has detected West Nile virus in seven mosquito pools. A mosquito pool is between 10 to 50 mosquitoes. The pools were collected on Aug. 3 from a rural area near Boardman.

Since that collection the area has been treated twice with fogging units. After that, mosquito pools were trapped on Tuesday and Wednesday. Those samples have been sent for testing to Oregon State University.

No humans in Oregon have tested positive for West Nile virus. In addition to Morrow County, mosquitoes carrying the virus have been found in Baker, Malheur, and Jackson counties.

The first mosquitoes carrying West Nile in Washington state were detected last month in the Burbank area. Since then, at least one woman has contracted the virus. She lives in Franklin County, works in Benton County, and visits Walla Walla County. She also didn’t feel sick. She was donating blood when a test showed she was carrying the virus it was announced earlier this month.
