The recent detection of a new strain of bird flu, D1.1, in dairy cattle in Nevada marks a significant concern for agriculture officials and health experts. This strain, distinct from others spreading in U.S. herds, stems from wild bird interactions and heightens questions around virus control in animals and their handlers. With prior strains like B3.13 affecting nearly 950 herds across the country, experts stress the critical need for continuous testing and monitoring to manage potential human exposures and outbreaks effectively, as seen with past severe illnesses linked to bird flu.
