Which species are reservoirs for Avian Influenza Virus (VND)?

Birds are considered the primary reservoirs for Avian Influenza Virus (VND). This virus is commonly found in wild birds, particularly waterfowl such as ducks, geese, and swans, which can carry the virus without displaying symptoms. This asymptomatic nature allows them to spread the virus widely, infecting domestic birds and potentially leading to outbreaks in poultry.

The role of birds as reservoirs is critical in the ecology of avian influenza because they can introduce the virus to new populations and environments. Wild birds shed the virus in their saliva, feces, and nasal secretions, facilitating transmission in various ecosystems. Domestic birds often come into contact with these wild species, increasing the risk of infection.

Other species listed, such as cattle, swine, and rabbits, do not serve as natural reservoirs for the Avian Influenza Virus. While they can become infected under certain circumstances, they are not the primary vectors or reservoirs for the virus in nature. Understanding the significance of birds in the transmission and ecology of avian influenza is vital for effective monitoring and control measures in public health and animal husbandry.
