Avian influenza found in red-tailed hawk, 2 bald eagles in Indiana
INDIANAPOLIS (WISH) — Added information about wild birds with avian influenza found in Indiana was provided this week by Indiana Department of Natural Resources.
The Indiana State Board of Animal Health on April 18 said federal authorities had confirmed avian influenza in a bald eagle, a hawk and a redhead duck.
On Tuesday, the Department of Natural Resources clarified that bird flu was found in two bald eagles — one in Starke County and another in Miami County — plus a red-tailed hawk in Johnson County. Purdue University’s Animal Disease Diagnostic Laboratory tested the raptors.
Natural Resources issued the clarification as the spring turkey hunting began. Michelle Benavidez Westrich, a wildlife health biologist with the state’s division of fish and wildlife, said that the current H5N1 strain has not been detected in wild turkeys, and she does not expect that to happen. She says wild turkeys have never been found with the bird flu.
The Indiana Department of Natural Resources says it’s partnered with the U.S. Department of Agriculture’s Wildlife Services to increase surveillance of wild birds. People who see waterfowl or raptors that are dead or appear sick are asked to report them using the Natural Resources’ online reporting tool.
Indiana isn’t the only state seeing flocks and wild birds contracting bird flu. The U.S. Department of Agriculture is keeping a database of outbreaks. Some zoos have changed how their birds are displayed to protect against the virus.
The state has found nine commercial flocks and one hobby flock with avian influenza. In Indiana, 171,224 turkeys and 17,279 ducks have been euthanized to prevent the spread of the bird flu.
Rising prices for eggs has been one effect of the outbreak, the worst in the United States since 2015.
The U.S. Centers for Disease Control and Prevention on Thursday night reported the first case of a person with avian influenza. The case was reported in Colorado. The person had “direct exposure to poultry” and was involved in the euthanasia of birds with H5N1. The patient reported fatigue for a few days as their only symptom and has since recovered. The person was being isolated and treated with the antiviral drug oseltamivir. The single case is not considered a high risk, but the CDC says it will continue to monitor for a possible outbreak.
Officials emphasize that bird flu doesn’t jeopardize the safety of meat or eggs or represent a significant risk to human health. No infected birds are allowed into the food supply, and properly cooking poultry and eggs kills bacteria and viruses.

Avian Flu Fast Facts from CNN
Avian influenza, also called avian flu or bird flu, is an illness that usually affects only birds. There are many different strains of avian flu: 16 H subtypes and 9 N subtypes. Only those labeled H5, H7 and H10 have caused deaths in humans. The most commonly seen and most deadly form of the virus is called “Influenza A (H5N1),” or the “H5N1 virus.”
Diagnosis/Treatment
Most cases of human bird flu infections are due to contact with infected poultry or surfaces that are contaminated with infected bird excretions: saliva, nasal secretions or feces.
Symptoms of avian flu include fever, cough, sore throat and sometimes severe respiratory diseases and pneumonia.
The CDC recommends oral oseltamivir (brand name: Tamiflu), inhaled zanamivir (brand name: Relenza) and intravenous permavir (brand name: Rapivab) for the treatment of human illness associated with avian flu.
The mortality rate is close to 60% for infected humans.
