Answer:Infected birds shed influenza virus in their saliva, nasal secretions, and feces. Susceptible birds become infected when they have contact with contaminated excretions or with surfaces that are contaminated with excretions or secretions. Wild bird avian influenza viruses of low pathogenicity mix with avian viruses in domesticated birds and become highly pathogenic in poultry. Domestic poultry 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 feces or feed) that have been contaminated with droppings that harbor the low-pathogenicity the virus.
