Avian Influenza (H5 Bird Flu)

What to Know:

• H5 bird flu is widespread in wild birds worldwide and is causing outbreaks in poultry and U.S. dairy cows with several recent human cases in U.S. dairy and poultry workers.
• While the current public health risk is low, Cass County Health Department is monitoring the situation carefully and working with local and state partners to assess and respond to exposure risks between people and affected animals.

• IDNR, IDPH, and IDOA monitoring avian influenza mortality events in waterfowl throughout Illinois (Press Release 12/20/2024)

The public is reminded not to handle or attempt to capture waterfowl or other wild birds displaying signs of illness.

IDNR will continue to monitor for HPAI mortality events throughout the state during the seasonal bird migration. Members of the public are encouraged to report concentrations of five or more deceased birds found at one location to IDNR district wildlife biologists by going online.

Due to risk of infection to other animals, dogs and other pets should be kept away from the carcasses of birds that may have died from HPAI. If carcasses need to be disposed of, IDNR recommends following guidance from the Illinois Department of Public Health (IDPH). IDNR is unable to assist with carcass removal from non-IDNR properties in most situations.
