Avian Influenza

Several months have passed since Kansas had a confirmed case of HPAI. Does that mean the outbreak is over? Previous HPAI outbreaks in the U.S. have subsided in summer, perhaps because during warmer months migratory birds that carry the virus settle down in their nesting grounds; also, the virus in the environment is rapidly inactivated by heat and sunlight. We hope this outbreak continues the historical trend of waning in the summer, but that isn't certain. We also need to be alert to the virus potentially reappearing in the fall, so poultry producers should remain vigilant, especially when fall approaches, reviewing their biosecurity activities to protect the health of their birds. 

We encourage poultry owners to continue monitoring their flocks. If you have birds showing symptoms of HPAI (see list of symptoms below), contact your veterinarian or call KDA toll-free at 833-765-2006. Or email us at KDA.HPAI@ks.gov and we will call you back.

Definitions (these official designations are defined by the World Organisation for Animal Health (OIE) and used by  KDA in cooperation with the USDA and OIE):

  • Non-poultry: Birds that are kept in a single household, the products of which are used within the same household exclusively, are not considered poultry, if they have no direct or indirect contact with poultry or poultry facilities.
  • Poultry: All birds reared or kept in captivity to produce any commercial animal products or for breeding for this purpose, fighting cocks used for any purpose, and all birds used for restocking supplies of game or for breeding for this purpose, until they are released from captivity.


What is Avian Influenza?

Highly pathogenic avian influenza (HPAI) is a rapidly spreading viral disease that can infect many types of birds.

Avian influenza is contagious. It exists naturally in many wild birds and can be transmitted by contact with infected birds or ingestion of infected food or water. Although extremely rare, humans and other mammals can be vulnerable to the disease.  

Symptoms to watch for: coughing, sneezing, nasal discharge, and other signs of respiratory distress; lack of energy and appetite; decreased water consumption; decreased egg production and/or soft-shelled, misshapen eggs; incoordination; and diarrhea. Avian influenza can also cause sudden death in birds even if they aren’t showing other symptoms.

If you suspect your flock contracted the disease, quarantine the affected birds and area immediately. Notify your veterinarian of any suspected cases or call the KDA Division of Animal Health at 833-765-2006 or email us at KDA.HPAI@ks.gov. No effective treatment for the disease has been found.  Infected animals must be humanely destroyed and disposed of properly to prevent the disease from spreading. 

Preventing HPAI

  • Prevent contact with wild birds, especially wild waterfowl. Remove any potential nesting areas for wild birds.
  • Cover and enclose outdoor feeding areas, and cover stored feed.
  • Take all possible steps to separate wild birds from having any access to your flock or their living area.
  • Clean and disinfect any vehicle tires or equipment that has been on other farms or other locations where there is poultry or wild birds.
  • Wear clean clothing, boots and shoes when in contact with your flock.
  • Restrict unauthorized people and vehicles.
  • Isolate new birds.
  • Stay informed about the health of birds in your area.
