Avian Influenza is also known as bird flu, is a type A influenza virus. It is lethal to poultry and is potentially fatal in humans. Avian Influenza is defined as emerging infectious disease (Bird flu (avian influenza), 2012). Water birds such as wild ducks are believed to be the carriers of all avian influenza type A viruses.The Avian Influenza Virus had its first outbreak in 1997 (Beigel et al. 2005), re-emerged in 2003 (Gao et al. 2013b) and evolved in 2013 (Gao et al. 2013a), its impact on the human population, especially in Asian and European continents has been detrimental to the human population.Avian influenza, known informally as avian flu or bird flu, is a variety of influenza caused by viruses adapted to birds. The type with the greatest risk is highly pathogenic avian influenza (HPAI).


Bird flu, also called avian influenza, is a viral infection that can infect not only birds, but also humans and other animals. Most forms of the virus are restricted to birds. H5N1 is the most.Avian influenza virus, such as H5N1 and H7N9, can even reach the blood circulation to infect cells in distant tissues (Taubenberger and Morens 2008; Tse et al. 2011). Attachment to cells via virus-binding receptors enables endocytic uptake resulting in recognition of the virus through innate receptors, which trigger intricate signaling networks to produce antiviral effector molecules that are.

Influenza viruses cause acute respiratory inflammation in humans and symptoms such as high fever, body aches, and fatigue. Usually these symptoms improve after several days; however, the 2009 pandemic H1N1 influenza virus (influenza A(H1N1)2009) is more pathogenic than seasonal influenza viruses and the pathogenicity of highly pathogenic H5N1 viruses is still higher.

Avian influenza virus classification. Influenza viruses are grouped into three types; A, B, and C. Only type A is known to infect animals and is zoonotic, meaning it can infect animals and also humans. Type B and C mostly infect humans and typically cause mild disease. Avian influenza viruses are extremely variable and are widespread among birds.

Avian influenza (AI) --the bird flu--is a virus that infects wild birds (such as ducks, gulls, and shorebirds) and domestic poultry (such as chickens, turkeys, ducks, and geese). There is flu for birds just as there is for humans and, as with people, some forms of the flu in birds are worse than others.

At the end of 2005, only 17 countries had H5N1 outbreaks in chickens, ducks, or humans (1). As of September 2007, the virus has circulated in 60.

The Spanish influenza pandemic, which stands as the single most fatal event in human history, killed an estimated 50 million people or more globally. 14 As noted, the causative agent was an avian-descended H1N1 virus and a direct progenitor of all of the influenza A viruses circulating in humans today. 2, 3 The high mortality associated with the 1918 virus appears to have been largely a result.

Abstract. This dissertation examines issues related to avian influenza (AI) disease. This is done via three essays that individually examine: (1) the impacts of climate change on the probability and expected numbers of AI outbreaks and associated economic loss; (2) the effects that media coverage of AI outbreaks has on meat demand in the United States, and (3) the potential effectiveness of AI.
