Avian Influenza
Avian Influenza is an infection caused by avian
(Bird) influenza (flu) viruses. 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 sick and kill them.
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 contaminated with
secretions or excretions from infected birds. Domesticated birds may become
infected with avian influenza virus through direct contact with infected
waterfowl or other infected poultry, or through contact with surfaces (such as
dirt or cages), or materials (such as water or feed) that have been
contaminated with the virus.
Infection with avian influenza
viruses in domestic poultry causes two main forms of disease that are
distinguished by low and high extremes virulence. The low pathogenic form may
go undetected and usually causes only mild symptoms (such as ruffled feathers
and a drop in egg production). however, the highly pathogenic form spreads more
rapidly through flocks of poultry. This form may cause disease that affects
multiple internal organs and has a mortality rate that can reach 90-100% often
within 48 hours.
