Avian Influenza

Avian Influenza in New York State

A type of highly pathogenic avian influenza (HPAI) called H5N1 has been found in poultry and wild birds in the United States, including New York State. There have been no reported cases of HPAI H5N1 in birds in NYC. For current reports of HPAI, visit the USDA APHIS 2022 Detections of HPAI and the NYS Department of Agriculture and Markets.

To report sick or dead chickens, turkeys and other poultry at any time, call the NYS Department of Agriculture and Markets at 518-457-3502.


Avian influenza, or bird flu, is a disease that is spread among birds and is caused by flu viruses. Water birds (such as ducks, geese, gulls, and swans) can carry bird flu without looking sick, but bird flu can cause sickness and death in poultry birds (such as chickens and turkeys). Infected birds carry the virus in their saliva, nasal fluid, and feces.

There are many types of bird flu viruses. The viruses that can cause severe disease and death in poultry are called highly pathogenic avian influenza (HPAI). Low pathogenic avian influenza viruses cause no signs of illness or mild disease in poultry.

Some bird viruses can infect humans and other animals, but the risk is low. How sick a person becomes depends on the type of bird flu. Symptoms can range from no or mild illness to severe disease and death.

Highly Pathogenic Avian Influenza

Transmission

Wild water birds (ducks, geese, gulls and swans) can carry HPAI virus without looking sick and spread HPAI virus to poultry birds. The virus can cause sickness and death in poultry birds (chickens and turkeys). The virus can spread quickly through groups of poultry and can be difficult to control. It can spread from an infected bird’s saliva, nasal fluid and feces.

The risk to the general population is low. It is rare for a person to be infected with HPAI . There have been no human cases reported in the U.S.

Though rare, a person can become infected after breathing in HPAI virus from the air, or from touching something that has the virus on it and then touching their mouth, eyes or nose. Most infections occur after extended and unprotected contact with infected birds. Poultry workers, backyard bird owners and wild bird handlers are at higher risk for HPAI.

Signs in Birds

Some wild water birds that have been infected may show no signs of illness. Signs of HPAI in poultry include:

  • Sudden death without signs of illness
  • Lack of energy or appetite
  • Decreased number of eggs or misshapen eggs
  • Swollen head, eyelids, wattles and hocks
  • Purple colored wattles, comb and legs
  • Respiratory issues, such as sneezing, coughing, runny nose, and difficulty breathing
  • Falling
  • Diarrhea

If you own or care for chickens or other types of poultry, learn more about how to protect them from bird flu by visiting the USDA and Cornell Cooperative Extension.

How to Protect Yourself

To protect yourself from infection:

  • Report groups of sick or dead birds immediately by calling 311.
    • For poultry, call the NYS Department of Agriculture and Markets at 518-457-3502.
    • For wild birds, call the NYS Department of Environmental Conservation at (718) 482-4922 or (518) 478-2203.
  • Avoid contact with birds that appear sick or have died.
  • Avoid contact with surfaces that have bird feces.
  • If you must touch sick or dead birds:
    • Wear gloves and a facemask.
    • Place dead birds in a double-bagged garbage bag.
    • Throw away your gloves and facemask after use.
    • Wash your hands well with soap and warm water.

Bird flu is not a risk to food safety. Poultry and eggs that are safely handled and cooked to an internal temperature of 165 degrees F are safe to eat.

If you feel sick after having contact with sick or dead birds, contact your health care provider.

Bird Flu in Cats

In 2016, over 100 cats and one person in NYC tested positive for a low pathogenic avian influenza known as H7N2. There is no current outbreak of H7N2 in NYC.
