Avian Influenza – Etiology, Pathogenesis and Interventions is available to download free in pdf / epub format.
Avian influenza, sometimes avian flu, and commonly called bird flu, refers to “influenza caused by viruses adapted to birds.” Of greatest concern is highly pathogenic avian influenza (HPAI). These influenza viruses occur naturally among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not get sick from them. However, avian influenza is very contagious among birds and can make some domesticated birds, including chickens, ducks, and turkeys, very ill. Infected birds shed influenza virus in their saliva, nasal secretions, and feces. Susceptible birds become infected when they have contact with contaminated secretions or excretions or with surfaces that are contaminated with secretions or excretions from infected birds.
