Which species can act as reservoir hosts for Fowl Pox/Avian Influenza?

• A. Waterfowl
• B. Pigeons
• C. Chickens
• D. Turkeys

Answer: (B)

A reservoir host is a species that harbors a pathogen and can shed it, keeping transmission going even when outbreak levels are low. In the context of Fowl Pox and Avian Influenza, pigeons can carry and shed these viruses, often with little or no obvious illness, which allows the viruses to persist in mixed bird populations and spread to susceptible poultry through droppings, secretions, or contaminated environments. Their frequent contact with both wild and domestic birds and their mobility make them effective bridge hosts, sustaining transmission cycles between species and locations. Waterfowl are well known as natural reservoirs for avian influenza, so they fit the reservoir concept for that disease, but the combination here highlights pigeons as a species capable of maintaining and dispersing both infections in ways that can influence domestic poultry outbreaks. Chickens and turkeys are highly susceptible and suffer outbreaks when infected, but they are less typically maintained as long-term reservoirs in the population.
