Mammals capable of transmitting avian influenza to poultry

Researchers have known for some time that a wide range of wild mammals, including raccoons and foxes - common visitors to farms and waterways across Delmarva - can be carriers of avian influenza.

More recently, however, researchers confirmed that some mammals are not only carriers, but that they also can transmit the virus to birds, raising new questions about how the disease may move in the environment and between farms.
