With mosquito control agencies and local county health departments around the state, Oregon Health Authority is testing adult mosquitoes and birds for mosquito-borne encephalitis.
Oregon Health Authority has stepped up its surveillance of mosquito-borne encephalitis. We are encouraging physicians, veterinarians, diagnostic laboratories and other health care providers to assist in this effort.
I found a single dead or ill bird. What do I do?
Birds are a natural host for West Nile virus; in Oregon particularly crows, ravens, jays, magpies, and sage grouse. A large or continuous die-off of birds may be a local indicator of WNV activity.
Contact one of the following Oregon agencies for collection and testing for West Nile virus surveillance:

- County health department resources
- Oregon Fish and Wildlife: (503) 947-6322, FAX: (503) 947-6330
I suspect I have a horse with WNV infection. What do I do?
Veterinarians are required to report horses with the appropriate clinical signs. Refer to West Nile Virus testing for further information and contact the Oregon Dept. of Agriculture at (503) 986-4760 before submitting horse samples.
Are other animals tested for WNV?
Any other animal suspected of having West Nile virus or other viruses carried by mosquitoes will be tested at a laboratory. If you have any questions, please call the state public health epidemiologist on call at Oregon Health Authority, Public Health Department, (971) 673-1111.
