USDA Works to Combat Bird Flu in Iowa

The National Animal Disease Center in Iowa is at the forefront of research aimed at combating the ongoing bird flu outbreak affecting U.S. livestock. With a dedicated team of 43 scientists, the facility focuses on understanding the virus's spread among animals, particularly in light of recent infections detected in dairy cows. Richard Webby, a flu researcher, emphasized the center's unique capabilities, which include working with dangerous pathogens like H5N1, and its collaboration with other research institutions to develop effective vaccines. Historically, the center has played a crucial role in addressing animal health crises, notably during the H1N1 flu pandemic in 2009, which reassured the public about the safety of pork consumption. This experience has positioned the Ames facility as a key player in the current bird flu situation, especially as researchers investigate the unexpected presence of the virus in the udders and milk of dairy cows. Kaitlyn Sarlo Davila, a researcher at the center, noted the surprising nature of these infections, as influenza is typically associated with respiratory illnesses. While efforts are underway to create a bird flu vaccine for poultry, challenges remain, and no approved vaccine is currently available for U.S. farms. Amy Baker, an award-winning researcher, is leading vaccine trials for cows, while also studying the virus's transmission among cattle. The research has revealed a rare genetic combination in the bird flu virus, prompting further investigation into its potential spread to humans.
