There have been no human cases of West Nile Virus identified in Marion County, but avoiding mosquitos is a good idea
(SALEM) - The first animal case of West Nile virus in Marion County has been identified in a Blue Jay. 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.
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.
The virus is transmitted through a mosquito bite. Humans, horses, and other mammals are at risk of contracting the virus. Although the West Nile Virus can be transmitted year-round in southern regions, cases are most commonly detected during late summer and early fall.
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 tiresIf 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. Follow label instructions when using any repellent.Make sure that doors and windows have tight-fitting screens. Repair or replace screens that have tears or holes.
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.
Anyone is at risk for contracting the virus. However, individuals over 50 years of age or with a compromised immune system, are at increased risk. A vaccine against West Nile virus has been developed for horses but there is no vaccine for humans as of yet.
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.
