11 More Mosquitoes Test Positive in Morrow County for West Nile Virus


Public Health officials are concerned about widespread West Nile Virus activity throughout the area and are urging residents of all ages to take the necessary steps to reduce their exposure to mosquitoes.

The North Morrow Vector Control District is reporting that West Nile Virus has been detected in 58 mosquito samples this year. The Oregon State Veterinary Diagnostic Laboratory reported on Sunday that 11 additional samples from mosquitoes collected last week have tested positive. The samples were from areas in and around Irrigon and Boardman. The West Umatilla Mosquito Control District has also reported four positive mosquito samples this year. The virus was initially detected on July 8 in both districts and has become more widespread since that time.

People are encouraged to take appropriate precautions to protect themselves against mosquito bites. Most people who become infected with West Nile Virus do not become ill. Some may develop mild flu-like symptoms such as fever, headache, body aches, and occasionally swollen lymph glands or a rash. In rare cases West Nile may cause encephalitis, or inflammation of the brain. Individuals with severe or unusual headaches should seek medical care as soon as possible. Residents of the district should remain vigilant in protecting themselves from mosquitoes and the diseases that they can carry, such as West Nile Virus.
