Fourth Dubois County Farm Records Avian Influenza
Dubois Co. - A fourth Dubois County farm has registered Avian Influenza.
DUBOIS4: Laboratory testing of a commercial flock of turkeys in Dubois County has identified H5 avian influenza virus. This is considered a presumptive-positive case, and samples are being verified at the USDA National Veterinary Services Laboratory (NVSL) in Iowa. This is the sixth farm (known as Dubois4) in Indiana to be diagnosed with avian influenza. Pending verification test results should indicate if the virus is the same as the index farm diagnosed on Feb. 9 and if the virus is highly pathogenic.
Depopulation efforts are underway on the premises, which houses 16,500 birds.
The location of Dubois4 is approximately 6/10 of a mile south from the Dubois3 site; therefore, a sixth 10-km circle control area has been established. All commercial poultry within this control area will be quarantined and tested regularly for the duration of this event (i.e., until the control area is lifted).
BOAH staff continue to reach out to known hobby/backyard poultry owners in the control areas to schedule testing of birds to ensure the virus is not present. To date, 74 hobby flocks have been sampled; laboratory testing determined them as negative. Hobby poultry owners in Southern Dubois County or Greene County should contact BOAH at 317-544-2387 to schedule testing at no charge.
BACKGROUND
On Feb. 9, 2022, a confirmed case of H5N1 highly pathogenic avian influenza (HPAI) was identified in a single commercial turkey flock in Dubois County. This is the first report of HPAI in commercial poultry in the United States since 2020 and the first in Indiana since 2016.
Samples were collected from the birds on Feb. 7 and submitted to the Indiana Animal Disease Diagnostic Laboratory (ADDL) at Purdue University after approximately one hundred birds died, flock appeared lethargic and decreased consumption of water. Tests indicated a likely infection of an H5 avian influenza virus. Under standard protocols, the results were reported to the Indiana State Board of Animal Health (BOAH), which authorized prompt transport of the samples to US Department of Agriculture’s National Veterinary Services Laboratory (NVSL) in Ames, IA for confirmatory testing.
NVSL confirmed that the virus present was a highly pathogenic strain of H5N1 (with a Eurasian H5 goose/Guangdong lineage). Upon confirmation of HPAI, the 29,000 turkeys in the flock (known as Dubois 1) were depopulated to prevent the spread of the disease in the area.
On Feb. 15 laboratory testing of a second commercial flock of turkeys in Dubois County has identified the H5 avian influenza virus (known as Dubois2). Upon confirmation of HPAI, the 26,473 turkeys in the flock were depopulated to prevent the spread of the disease in the area.
On Feb. 17, laboratory testing of a commercial flock of turkeys in Greene County has identified the H5 avian influenza virus (known as Greene1). A total of 48,000 turkeys in the flock were depopulated.
On Feb. 18, laboratory testing identified H5 avian influenza (AI) in a commercial turkey flock in Greene County (known as Greene2). A total of 15,400 turkeys were depopulated.
On Feb. 22, laboratory testing identified H5 AI in commercial turkeys in Dubois County (Dubois3) about 2.5 miles west of Dubois1. H5N1 was subsequently confirmed by NVSL on Feb. 24. A total of 35,908 turkeys were depopulated.
A 10-km control area (CA) is established around each HPAI-affected flock. All commercial flocks in the control areas must be tested for avian influenza at least weekly. Small, hobby flocks are also subject to testing. A surveillance zone is also established in the 10-km circle beyond the control area. Flocks in the surveillance zone must be tested every other week.
RESPONSE As part of existing avian influenza response plans, federal and state partners are working jointly on additional surveillance and testing in areas around the affected flocks. The United States has the strongest AI surveillance program in the world, and USDA is working with its partners to actively look for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.
BOAH is working with multiple state and federal partners to respond to this event, including Indiana Department of Health, Indiana Department of Homeland Security, Indiana Department of Natural Resources, Indiana Department of Environmental Management, and USDA Veterinary Services, Wildlife Services and Farm Service Agency. PUBLIC ADVISORIES Food Safety
Avian influenza does not present a food safety risk; poultry and eggs are safe to eat. Officials are not aware of any public health significance with this virus. No cases of human infection have been reported. Human health agencies will be monitoring workers and others in contact with birds to monitor for influenza-like illness.
Animal Health
Hobby poultry owners are encouraged to be aware of the signs of avian influenza and report illness and/or death to the USDA Healthy Birds Hotline: 866-536-7593. Callers will be routed to a state or federal veterinarian in Indiana for a case assessment. Dead birds should be double-bagged and refrigerated for possible testing. Signs include: sudden death without clinical signs; lack of energy or appetite; decreased egg production; soft-shelled or misshapen eggs; swelling or purple discoloration of head, eyelids, comb, hocks; nasal discharge; coughing; sneezing; lack of coordination; and diarrhea.

Human Health
Recent detections of highly pathogenic avian influenza A H5N1 viruses (H5N1 bird flu) in wild birds and poultry pose a low risk to the health of the general public; however, rare human infections are possible. Human infections are most likely to be rare and happen in people with recreational or occupational exposures involving prolonged, unprotected close contact with infected birds or contaminated environments. CDC is taking routine preparedness measures to be ready in case human infections with these viruses happen. IDOH offers the following guidance documents for poultry growers and emergency responders to protect their health:
