/ West Nile Virus InfoWest Nile Virus in Marion County
The first animal case of West Nile virus has been identified in a Blue Jay in Marion County. This is the first case of West Nile virus to come from Marion County since the virus was first introduced into the United States in 1999. There have been no human cases of West Nile Virus identified in Marion County.
West Nile virus is transmitted through the bite of a mosquito. The best defense against West Nile virus is to prevent mosquito bites. People can take the following steps to reduce their chance of being bitten:
- Eliminate all sources of standing water that can support mosquito breeding such as leaf-clogged gutters, birdbaths, and old tires;
- If possible avoid being outside at dusk and dawn when mosquitoes are most active;
- Wear long pants, long sleeve shirts, and other protective clothing while outdoors;
- Wear insect repellent, preferably one that contains DEET or Picaridin. Follow label instructions when using any repellent; further information can be found at http://oregon.gov/DHS/ph/acd/diseases/wnile/wnvprevent.shtml
- Make sure that doors and windows have tight-fitting screens. Repair or replace screens that have tears or holes.
West Nile virus is an infection that lives in birds. It is spread when a mosquito feeds on an infected bird and then bites a human. Birds cannot transmit the illness directly to humans, nor is it transmitted from other animals to humans or from person-to-person. Most people who are infected with West Nile virus will have no symptoms, or those that do have symptoms are usually mild, with fever and flu-like illness. Severe infections may cause encephalitis (inflammation of the brain), and rarely, death. The risk of severe illness is greater in persons over 50 years of age. A vaccine against West Nile virus has been developed for horses but there is no vaccine for humans.
People who find a bird that is known to have died due to illness within the past 24 hours should call 503-588-5401 to ask about testing. Only crows, jays, ravens and magpies will be tested for West Nile virus.
