Which of the following is true about ducks and geese in relation to VND?

In the context of viral Newcastle disease (VND), it is important to understand the hosting characteristics of different avian species. Ducks and geese, particularly certain breeds, are known to exhibit a degree of resistance to the effects of VND. This resistance means that these birds can harbor the virus without succumbing to severe illness, making them less vulnerable compared to other species like chickens.

This characteristic is significant because while they may carry the virus, their ability to withstand the disease does not mean that they are free from infection or that they do not participate in the transmission dynamics of the disease. Instead, their resistance allows them to serve as carriers in a poultry farming environment, which could pose risks for the spread of VND to more susceptible species. Therefore, the assertion that ducks and geese are resistant highlights an important aspect of disease ecology and poultry management in relation to VND.
