Health officials in Morrow County say they've detected West Nile Virus in mosquitoes trapped at two county test sites. That makes Morrow the third Oregon county this year to detect the presence of the virus.

West Nile carrying mosquitoes have also been found in Malheur and Jackson counties. But so far, Oregon hasn't had any reported cases of human infections.

Around the country, however, this year is shaping up to be one of the worst on record.

According to the latest federal count, West Nile has killed 26 people this summer, mostly in Texas.

Still, only about 1 in 5 people who get the virus, actually get sick. Typical symptoms include a fever, accompanied by headaches and nausea. Most people get better in 3 to 6 days.

In rare cases, however, West Nile can infect a patient's central nervous system. And that's when the disease becomes potentially life threatening.

Morrow County Vector Control District Manager Greg Barron says his team is stepping up it's spraying regimen there. In the meantime, he says people should take precautions to protect themselves against mosquito bites.
