The disease, known as bird flu, has been circulating in wild birds along the U.S. East Coast this year. An outbreak was reported on Wednesday in an Indiana turkey flock, the nation's first case in a commercial poultry operation since 2020.

According to the USDA, as of Feb 15, 2022, in 2022 the Highly Pathogenic Avian Influenza has been found in the following:

Dubois County, Indiana on 2/8/2022 in Commercial Turkeys
Fauquier County, Virginia on 2/12/2022 in Backyard Mixed Species Birds (non-poultry)
Fulton County, Kentucky 2/12/2022 in Commercial Broiler Chicken

According to the USDA, no human case of these avian flu viruses has yet to be detected in the U.S.

Given these additional findings, anyone involved with poultry - commercial or backyard flocks alike - should review their biosecurity plan and enhance their biosecurity practices to assure the health of their birds. APHIS has materials about biosecurity, including videos, checklists, and a toolkit available for producers on our website.

In addition to practicing good biosecurity, all bird owners should prevent contact between their birds and wild birds and report sick birds or unusual bird deaths to State/Federal officials, either through their state veterinarian or through USDA's toll-free number at 1-866-536-7593. Additional information on biosecurity for backyard flocks can be found at http://healthybirds.aphis.usda.gov.

Mexico says will restrict poultry products from Indiana after bird flu outbreak

Mexico's agriculture ministry said on Thursday it will ban the entry of poultry products originating or coming from the U.S. state of Indiana after an outbreak of highly pathogenic avian flu. 

Additional background

Avian influenza (AI) is caused by an influenza type A virus which can infect poultry (such as chickens, turkeys, pheasants, quail, domestic ducks, geese, and guinea fowl) and is carried by free flying waterfowl such as ducks, geese and shorebirds. AI viruses are classified by a combination of two groups of proteins: hemagglutinin or "H" proteins, of which there are 16 (H1-H16), and neuraminidase or "N" proteins, of which there are 9 (N1-N9). Many different combinations of "H" and "N" proteins are possible. Each combination is considered a different subtype and can be further broken down into different strains which circulate within flyways/geographic regions. AI viruses are further classified by their pathogenicity (low or high)--the ability of a particular virus strain to produce disease in domestic chickens.

Signs and Symptoms of Avian Influenza A Virus Infections in Humans

The reported signs and symptoms of avian influenza A virus infections in humans have ranged from mild to severe and included  conjunctivitis, influenza-like illness (e.g., fever, cough, sore throat, muscle aches) sometimes accompanied by nausea, abdominal pain, diarrhea, and vomiting, severe respiratory illness (e.g., shortness of breath, difficulty breathing, pneumonia, acute respiratory distress, viral pneumonia, respiratory failure), neurologic changes (altered mental status, seizures), and the involvement of other organ systems. Asian lineage H7N9 and HPAI Asian lineage H5N1 viruses have been responsible for most human illness worldwide to date, including most serious illnesses and highest mortality.
