Highly pathogenic avian influenza continues to devastate poultry flocks throughout the United States, as well as cause significant illness in cattle, said David Diemert, MD, professor of medicine and professor of microbiology, immunology, and tropical medicine at George Washington University in Washinton, DC, in an interview.

With egg prices soaring, the US is considering vaccinating laying chickens, which have been hit particularly hard by the avian influenza outbreak.
