Bird Flu in Birds, Cats and Dogs

Bird flu is a disease caused by an avian influenza virus that can be spread to humans from direct contact with birds and possibly other animals such as cats and dogs.
Bird Flu Need to Know
What you need to know about bird flu addresses some of the most important questions people have about avian flu. This is a good a place to start reading before delving deeper into the topic of avian bird flu.
Center for Disease Control Avian Influenza Fact Sheet
The Center for Disease Control (CDC) in Atlanta has published this fact sheet on avian influenza. Information includes: the disease in birds and humans, human health risks during outbreaks and treatment and vaccination.
World Health Organization Avian Flu Fact Sheet
The World Health Organization (WHO) fact sheet on avian influenza summarizes the most important bird flu information. It includes: what the disease is, it's history, the role of birds, clinical features in humans, and countries where the disease has been found in animals and humans.
What is H5N1?
H5N1 is an Influenza A avian influenza virus of the H5N1 subtype. H5N1 is also known as bird flu in the media. H5N1 infection in humans has caused the death of more than 58 per cent of those infected.
United States Department of Agriculture Bird Flu Fact Sheet
The USDA bird flu fact sheet focuses on the disease in birds. Issues addressed include: control and prevention in commercial and backyard flocks of poultry as well as the surveillance of wild birds.
The Center for Infectious Disease Research and Policy Avian Flu Info
The Center for Infectious Disease Research and Policy (CIDRAP) of the University of Minnesota has published this information on avian influenza infection in humans. The information is technical and ranges from what kind of virus is the avian flu virus, laboratory testing of the virus to using seasonal flu vaccines and food safety issues.
How do Experts Predict How Many People a Pandemic Would Kill?
No one really knows how many people a pandemic would kill, but experts make their best guess based on previous pandemics.
Bird Flu Endemic Countries
Countries where bird flu is considered to be endemic in birds.
WHO map of human cases of H5N1 avian influenza
Latest world map from the World Health Organization of confirmed cases of H5N1 avian influenza in humans since 2003.
WHO map of cases of H5N1 avian influenza in poultry and wild birds
Latest world map from the World Health Organization of confirmed cases of H5N1 avian influenza in poultry and wild birds since 2003.
Where CDC is Present in the World
The US Centers for Disease Control has 200 staff members working in 44 countries, but the CDC does not work in all of the countries where bird flu is endemic.
Updated H5N1 Bird Flu Deaths and Survival in Humans Since 2003
Human cases of bird flu H5N1 avian influenza since 2003 are shown in this table of mortality and survival listed by country.
WHO Current Pandemic Phase
The World Health Organization (WHO) determines the pandemic phase based on surveillance data, laboratory tests, clinical findings and case studies.
Definition of LPAI and HPAI Bird Flu
The difference between HPAI and LPAI bird flu is the pathogenicity of the viruses. Highly Pathogenic Avian Influenza, HPAI, kills nearly all of the birds it infects and Low Pathogenic Avian Influenza, LPAI, kills less than 75 per cent of the birds it infects. The World Organization for Animal Health (OIE) determines pathogenicity by laboratory tests on chicks.
Antigens and Avian Influenza
The definition of antigen is described here focussing on the types of antigens on Influenza A viruses such as hemagglutinin and neuraminidase, present in bird flu, avian influenza, viruses. H5N1 is an Influenza A virus.
Hemagglutinin and Bird Flu Vaccine
The definition of hemagglutinin and its role in bird flu is important to know when exploring all of the issues surrounding vaccines and avian influenza, also known as bird flu.
Neuraminidase and Bird Flu
The definition of neuraminidase and its role in bird flu is important to know in order to understand avian influenza, bird flu, better and some of the issues surrounding vaccine production for bird flu.
Definition of Endemic Bird Flu
Endemic bird flu is a relative term that indicates that bird flu regularly occurs, in birds, in a specified area, country or region.
Definition of Virulence of Bird Flu
The definition of virulence in bird flu, or avian flu, means how effective the bird flu virus is at infecting and killing the target organism, whether human or animal.
Can Dogs Get Bird Flu?
Dogs are not likely to get bird flu, but a dog was reported to have died from H5N1 avian flu in Azerbaijan in May 2006.
H5N1 Bird Flu and H5N1 Avian Flu
H5N1 bird flu or H5N1 avian flu is an avian influenza virus of the H5N1 subtype. H5N1 infection in humans has caused the death of more than 59 per cent of those infected with the disease.
What are Cytokines?
Cytokines are small proteins involved in cell signalling. Large numbers of cytokines are found in bird flu victims as a result of an exaggerated immune response called a cytokine storm.
What is a Cytokine Storm?
Cytokine storm is a term used to describe an exaggerated immune response by the human body releasing a flood of cytokines in response to an elevated number of disease-causing virus present.
Reassortment
Reassortment of viruses means that viruses of different types exchange genetic material resulting in a genetically different virus. In the case of bird flu, the fear is that a virulent bird flu virus could infect humans and reassort with a common human flu virus. The exchange of genetic material could result in a deadly virus that is as easily transmissible from one person to another as the common seasonal flu viruses.

WHO Frequently Asked Questions
The World Health Organization (WHO) has put together a list of Frequently Asked Questions (FAQs).
Pandemic Phase
The pandemic phase is based on a scale of 1-6 defined by the World Health Organization. 1 is low risk of human cases, meaning little risk of pandemic flu while a ranking of 6 means a new flu virus is very contagious and spreading.
CDC Frequently Asked Questions
The Center for Disease Control (CDC) in Atlanta, GA, answers some of your questions in this informative page.
USDA Frequently Asked Questions
The United States Department of Agriculture (USDA) goes deep to answer questions from farmers and the general public.
Cats and Bird Flu
Cats have been killed by H5N1 bird flu known as avian bird flu or avian influenza but cats are not the natural hosts of bird flu.
Why Your Backyard Chickens Won't Give You or Anyone Else Avian Flu
Backyard chickens and other poultry are not likely to be a major cause in transmitting avian flu to other birds or in spreading avian flu around the world.
Are Backyard Chickens Causing Bird Flu?
Raising chickens and other poultry in backyards has often been blamed for spreading bird flu but commercial poultry operations are likely a greater cause for avian flu concern.
Dogs and Bird Flu
Dogs can get at least two types of avian influenza, H5N1 bird flu and H3N8 horse flu, another avian flu strain.
Cleaning Your Bird Bath and Bird Flu Prevention
Bird baths may be reservoirs for bird flu if birds infected with a highly pathogenic avian influenza use them. Learn how to clean your bird bath safely and prevent bird flu.
Prevent Bird Flu in Dogs and Cats
Prevent bird flu in dogs and cats by keeping your pet away from sources of avian flu.
Dogs and Bird Flu
Bird flu in dogs is not common, but there is one confirmed case of a dog dying from H5N1 bird flu. In addition, dogs have been infected with H3N8 bird flu, also known as horse flu.
Guidance for Non-Confinement Poultry Farmers
Non-confinement poultry farmers (such as free range poultry operations) should take a look at these recommendations made by the USDA.
Report Sick or Dead Farm Birds
Call 1-866-536-7593 at the United States Department of Agriculture to report dead or sick farm birds. The USDA's Veterinary Service Biosecurity for the Birds is a campaign to promote avian health. The campaigns motto is: Look for signs. Report sick birds. Practice backyard biosecurity.
Report Sick or Dead Wild Birds
If you find a sick or dead wild bird, you should report it to the proper authority in your state. If you live in the US, click on your state to find the address and telephone number of the authority you should contact. Reported cases of sick and dead birds allow health authorities track diseases and prevent outbreaks.
What Hunters Should Know About Bird Flu
What Hunters Should Know About Bird Flu is a publication by the Alaska Department of Fish and Game. It shows hunters how to safely handle carcasses, cook game and also answers some basic questions about bird flu.
