Can hunters get West Nile Virus from eating infected game birds?
Some game birds have tested positive for West Nile Virus (WNV). However, there is no evidence of human infection by consumption of properly cooked infected game. Hunters are likely at higher risk of infection by mosquito exposure, particularly in wetland environments. Protective measures should be taken to prevent mosquito exposure while hunting. There are extremely rare cases of laboratory workers contracting WNV through accidental exposure to infected tissues and blood. Hunters should wear gloves when dressing (cleaning) the birds to protect against accidental injury and exposure to blood. Consult with a physician immediately if an injury occurs to discuss the risk of WNV exposure. To prevent exposure to any infectious organisms carried by game species, hunters should wash hands with soap and water after handling carcasses and should thoroughly cook the meat.
Under normal conditions, humans are unlikely to be infected with West Nile Virus by handling a sick or dead animal. However, there are a number of other infections that could potentially result from handling an animal. To protect yourself from exposure to any illness, you should wear gloves or put a plastic bag over your...Read Full Answer
This is an issue of great concern, as these populations are already struggling to survive in the current environment. If some of these species are more vulnerable to fatal WNV infection, WNV may ultimately lead to their extinction or significantly set back the progress of the recovery programs.Read Full Answer
Experimentally, it was found that this might be possible. However, there has been no evidence to indicate that West Nile Virus can be naturally transmitted to cats or dogs that carry or consume infected animals. Dogs and cats can be infected with West Nile Virus through the bite of a mosquito, so minimizing their...Read Full Answer
At this time, there is not a West Nile Virus vaccine approved for use in birds. The Centers for Disease Control and Prevention, in collaboration with several organizations and laboratories, is developing and testing vaccines for use in birds. Many zoos and wildlife centers have been using the Fort Dodge horse vaccine (West...Read Full Answer
White-nose syndrome is an emergent disease of hibernating bats that has spread from the northeastern to the central United States at an alarming rate. Since the winter of 2007-2008, millions of insect-eating bats in at least 29 states and five Canadian provinces have died from this devastating disease. The disease is named...Read Full Answer

Curlews are very attentive parents and fly close to intruders and alarm call to distract them from their young broods. USGS scientists take advantage of this behavior by using a mist net to sweep birds out of the air when they approach. In June 2007, USGS scientists used this approach to tag 13 curlews with satellite transmitters at their southern breeding area in Alaska. They use satellite telemetry to track these birds, in order to map their migration routes and find the location of their nonbreeding areas.
