INDIANA— The highly pathogenic avian influenza (bird flu) has been confirmed in wild birds across Indiana, including Greene County, adding a new dimension to the outbreak that recently affected commercial farms in the state.
The Indiana Department of Natural Resources (DNR) announced the findings in a news release on Friday, confirming cases in multiple wild bird species and counties.
The detection in wild birds follows an earlier outbreak this month, during which avian influenza was confirmed at five commercial duck farms in northern Indiana.
The new cases recorded by the U.S. Department of Agriculture Wildlife Services and the DNR include:
- A blue-winged teal duck was found in Greene County in southwest central Indiana.
- Dead black vultures were found in Jefferson County in southern Indiana.
- Similar cases involving dead black vultures are also suspected in Franklin County in southeast central Indiana.
The DNR advises the public that signs of bird flu in waterfowl and raptors include sudden death, neurological impairment (such as tremors or lack of coordination), lack of energy and appetite, and swelling of the head, neck, and eyes.
Public Risk Remains Low, but Caution Advised
Despite the spread to wild populations, the U.S. Centers for Disease Control and Prevention (CDC) believes the public health risk from bird flu is low. However, health officials stress that humans can contract the virus.
The public is strongly advised to avoid contact with sick waterfowl and other wildlife.
The DNR has issued safety guidelines for individuals who must handle a carcass:
- Use disposable gloves and a mask.
- Double-bag the carcass.
- Wash your hands thoroughly afterward.
Additionally, to protect other domestic and agricultural animals—including poultry, cattle, and cats—which are also susceptible to the virus, harvested waterfowl should be processed and disposed of away from these animals, and good biosecurity measures should be practiced.
The Indiana Department of Health advises individuals to contact them if they develop symptoms such as eye irritation, fever, cough, or other flu-like symptoms after contact with waterfowl. They can be reached at 317-233-7125 during business hours or 317-233-1325 after hours.
