Wild Bird Testing Q & A
Q: Why did the Oklahoma State Department of Health (OSDH) test dead birds?
A: Very early in the course of this national epidemic, it was recognized that dead bird sightings, especially of dead crows, blue jays, or birds of prey provided an early warning signal that West Nile virus was spreading bird-to-mosquito in a geographic area. As a part of Oklahoma’s comprehensive West Nile virus monitoring program, the Oklahoma State Department of Health set up a hotline for persons to report dead birds and provided free West Nile virus testing of some of these birds. Because West Nile virus tends to cause noticeable mortality in wild birds before human cases of disease begin to occur, the testing of dead birds has helped define the period of public health risk and guide mosquito control activities in some communities.
Q: Is the State Health Department still testing dead birds for West Nile Virus?
A: No. After conducting wild bird surveillance in Oklahoma for the past four years (2001-2004), the OSDH has made the decision to stop routine testing of dead birds for West Nile virus. Oklahomans were extremely helpful in reporting and delivering dead birds to our local health departments for testing and we learned much about the pattern and spread of this disease through this program. Now that West Nile virus is an established seasonal health threat in Oklahoma, we are focusing our resources on prevention and control of this disease.
Q: What should I do if I find a dead bird in my yard?
A: Touching dead birds does not spread West Nile virus, but it is recommended to avoid bare-hand contact when handling dead birds to avoid exposure to potentially harmful bacteria such as Salmonella. Gloves or an inverted plastic bag to cover your hand can be used to pick up the dead bird. Then place the dead bird in a small garbage bag and dispose in an outdoor trash receptacle.
If several birds are found dead during a short time period (1-2 days) in the same vicinity, the cause of death is likely to be poisoning or electrocution. These types of dead bird reports should be forwarded to the Oklahoma Department of Wildlife Conservation for possible investigation.
Q: What should I do if I see a dying bird or a bird exhibiting unusual behavior?
A: If a wild bird is suffering (or you have some other special concern about the situation), you should contact your local animal control officer, game warden or a licensed wildlife rehabilitator. Concerns about an ill pet bird or domestic fowl should be directed to your personal veterinarian.
Q: What was learned from testing dead birds?
A: Since its introduction into Oklahoma in 2002, West Nile virus is now considered a potential health threat in all areas of the state. Three years of intense surveillance activities have consistently shown that West Nile virus season in our state is May to November. The greatest period of risk for human infections is July through October. West Nile virus poses a potential risk to people across Oklahoma, especially those in the northeastern and northwestern parts of the state. The best way to prevent West Nile infection is to apply insect repellents that contain active ingredients such as DEET or Picaridin when engaging in outdoor activities from July through October. We also encourage you to eliminate or treat standing water around the home to reduce mosquito breeding sites and to take extra care to use repellent and protective clothing during the evening and early morning hours when mosquitoes that transmit West Nile virus are most active.
